NAME
       xterm - terminal	emulator for X

SYNOPSIS
       xterm [-toolkitoption ...] [-option ...]

DESCRIPTION
       The  xterm  program is a	terminal emulator for the X Window System.  It
       provides	DEC VT102/VT220	(VTxxx)	and Tektronix 4014  compatible	termi-
       nals  for  programs that	cannot use the window system directly.	If the
       underlying operating system  supports  terminal	resizing  capabilities
       (for  example,  the  SIGWINCH  signal  in systems derived from 4.3bsd),
       xterm will use the facilities to	notify programs	running	in the	window
       whenever	it is resized.

       The  VTxxx  and	Tektronix 4014 terminals each have their own window so
       that you	can edit text in one and look at graphics in the other at  the
       same  time.   To	maintain the correct aspect ratio (height/width), Tek-
       tronix graphics will be restricted to the largest  box  with  a	4014's
       aspect  ratio  that will	fit in the window.  This box is	located	in the
       upper left area of the window.

       Although	both windows may be displayed at the same time,	one of them is
       considered  the ``active'' window for receiving keyboard	input and ter-
       minal output.  This is the window that contains the text	 cursor.   The
       active  window  can  be	chosen	through	 escape	 sequences,  the  ``VT
       Options'' menu in the VTxxx window, and the ``Tek Options'' menu	in the
       4014 window.

EMULATIONS
       The  VT102  emulation  is fairly	complete, but does not support autore-
       peat.  Double-size characters  are  displayed  properly	if  your  font
       server  supports	 scalable  fonts.   Blinking  characters are partially
       implemented; the	emulation is functional	but does not have the  appear-
       ance of a real VT102.  The VT220	emulation does not support soft	fonts,
       it is otherwise complete.  Termcap(5)  entries  that  work  with	 xterm
       include	``xterm,''  ``vt102,'' ``vt100'' and ``ansi,'' and xterm auto-
       matically searches the termcap file in this order for these entries and
       then  sets the ``TERM'' and the ``TERMCAP'' environment variables.  You
       may also	use ``vt220,''	but must set the terminal emulation level with
       the decTerminalID resource.

       Many  of	 the special xterm features may	be modified under program con-
       trol through a set of escape  sequences	different  from	 the  standard
       VT102 escape sequences.	(See the Xterm Control Sequences document.)

       The  Tektronix  4014 emulation is also fairly good.  It supports	12-bit
       graphics	addressing, scaled to the window size.	 Four  different  font
       sizes and five different	lines types are	supported.  There is no	write-
       through or defocused mode support.  The	Tektronix  text	 and  graphics
       commands	 are recorded internally by xterm and may be written to	a file
       by sending the COPY escape sequence (or through the Tektronix menu; see
       below).	 The  name  of	the  file will be ``COPYyyyy-MM-dd.hh:mm:ss'',
       where yyyy, MM, dd, hh, mm and ss  are  the  year,  month,  day,	 hour,
       minute  and  second when	the COPY was performed (the file is created in
       the directory xterm is started in, or the home directory	 for  a	 login
       xterm).

       Not all of the features described in this manual	are necessarily	avail-
       able in this version of xterm.  Some (e.g., the	non-VT220  extensions)
       are  available only if they were	compiled in, though the	most commonly-
       used are	in the default configuration.

OTHER FEATURES
       Xterm automatically highlights the text cursor when the pointer	enters
       the  window  (selected) and unhighlights	it when	the pointer leaves the
       window (unselected).  If	the window is the focus	window,	then the  text
       cursor is highlighted no	matter where the pointer is.

       In VT102	mode, there are	escape sequences to activate and deactivate an
       alternate screen	buffer,	which is the same size as the display area  of
       the  window.   When activated, the current screen is saved and replaced
       with the	alternate screen.  Saving of lines scrolled off	the top	of the
       window is disabled until	the normal screen is restored.	The termcap(5)
       entry for xterm allows the visual editor	vi(1) to switch	to the	alter-
       nate  screen  for  editing  and to restore the screen on	exit.  A popup
       menu entry makes	it simple to switch between the	normal	and  alternate
       screens for cut and paste.

       In either VT102 or Tektronix mode, there	are escape sequences to	change
       the name	of the windows.	 Additionally, in VT102	mode, xterm implements
       the window-manipulation control sequences from dtterm, such as resizing
       the window, setting its location	on the screen.

       Xterm allows character-based applications to receive mouse events (cur-
       rently  button-press  and  release events, and button-motion events) as
       keyboard	control	sequences.  See	Xterm Control Sequences	for details.

OPTIONS
       The xterm terminal emulator accepts all of the standard X Toolkit  com-
       mand line options as well as the	following (if the option begins	with a
       `+' instead of a	`-', the option	is restored  to	 its  default  value).
       The  -version  and  -help  options are interpreted even if xterm	cannot
       open the	display, and are useful	for testing and	configuration scripts:

       -version
	       This  causes  xterm  to	print a	version	number to the standard
	       output.

       -help   This causes xterm to print out a	verbose	message	describing its
	       options.	 The message is	written	to the standard	error.

       The other options are used to control the appearance and	behavior.  Not
       all options are necessarily configured into your	copy of	xterm.

       -132    Normally, the  VT102  DECCOLM  escape  sequence	that  switches
	       between	80 and 132 column mode is ignored.  This option	causes
	       the DECCOLM escape sequence to be  recognized,  and  the	 xterm
	       window will resize appropriately.

       -ah     This  option  indicates	that xterm should always highlight the
	       text cursor.  By	default, xterm will display a hollow text cur-
	       sor  whenever  the focus	is lost	or the pointer leaves the win-
	       dow.

       +ah     This option indicates that xterm	should do  text	 cursor	 high-
	       lighting	based on focus.

       -ai     This  option  disables  active icon support if that feature was
	       compiled	into xterm.  This is equivalent	to setting  the	 vt100
	       resource	activeIcon to FALSE.

       +ai     This  option  enables  active  icon support if that feature was
	       compiled	into xterm.  This is equivalent	to setting  the	 vt100
	       resource	activeIcon to TRUE.

       -aw     This  option  indicates that auto-wraparound should be allowed.
	       This allows the cursor to automatically wrap to	the  beginning
	       of the next line	when when it is	at the rightmost position of a
	       line and	text is	output.

       +aw     This  option  indicates	that  auto-wraparound  should  not  be
	       allowed.

       -b number
	       This  option  specifies	the size of the	inner border (the dis-
	       tance between the outer edge of the characters and  the	window
	       border) in pixels.  The default is 2.

       +bc     turn  off text cursor blinking.	This overrides the cursorBlink
	       resource.

       -bc     turn on text cursor blinking.  This overrides  the  cursorBlink
	       resource.

       -bcf milliseconds
	       time text cursor	is off when blinking

       -bcn milliseconds
	       time text cursor	is on when blinking

       -bdc    Set the vt100 resource colorBDMode to FALSE, disabling the dis-
	       play of characters with bold attribute as color

       +bdc    Set the vt100 resource colorBDMode to TRUE, enabling  the  dis-
	       play  of	 characters  with  bold	attribute as color rather than
	       bold

       -cb     Set the vt100 resource cutToBeginningOfLine to FALSE.

       +cb     Set the vt100 resource cutToBeginningOfLine to TRUE.

       -cc characterclassrange:value[,...]
	       This sets classes indicated by the given	ranges	for  using  in
	       selecting  by  words.   See  the	 section  specifying character
	       classes.

       -cjk_width
	       Set the cjkWidth	resource to ``true''.  When turned on, charac-
	       ters  with  East	 Asian Ambiguous (A) category in UTR 11	have a
	       column width of 2.  Othrwise, they have a column	 width	of  1.
	       This may	be useful for some legacy CJK text terminal-based pro-
	       grams assuming box drawings and others to have a	 column	 width
	       of 2.  The default is ``false''

       +cjk_width
	       Reset the cjkWidth resource.

       -class string
	       This  option  allows  you  to  override xterm's resource	class.
	       Normally	it is ``XTerm'', but can be set	to another class  such
	       as ``UXTerm'' to	override selected resources.

       -cm     This  option  disables  recognition of ANSI color-change	escape
	       sequences.

       +cm     This option enables recognition	of  ANSI  color-change	escape
	       sequences.  This	is the same as the vt100 resource colorMode.

       -cn     This  option indicates that newlines should not be cut in line-
	       mode selections.

       +cn     This option indicates that newlines should be cut in  line-mode
	       selections.

       -cr color
	       This  option  specifies	the color to use for text cursor.  The
	       default is to use the same foreground color that	 is  used  for
	       text.

       -cu     This  option  indicates	that xterm should work around a	bug in
	       the more(1) program that	causes it to incorrectly display lines
	       that  are exactly the width of the window and are followed by a
	       line beginning with a tab (the leading tabs are not displayed).
	       This option is so named because it was originally thought to be
	       a bug in	the curses(3x) cursor motion package.

       +cu     This option indicates that xterm	should	not  work  around  the
	       more(1) bug mentioned above.

       -dc     This option disables the	escape sequence	to change dynamic col-
	       ors: the	vt100 foreground and background	colors,	the text  cur-
	       sor  color,  the	mouse cursor foreground	and background colors,
	       the Tektronix emulator foreground and  background  colors,  and
	       highlight color.

       +dc     This  option enables the	escape sequence	to change dynamic col-
	       ors.

       -e program [ arguments ... ]
	       This option specifies the program (and its command  line	 argu-
	       ments)  to be run in the	xterm window.  It also sets the	window
	       title and icon name to be the basename  of  the	program	 being
	       executed	 if  neither  -T nor -n	are given on the command line.
	       This must be the	last option on the command line.

       -en encoding
	       This options determines	the  encoding  on  which  xterm	 runs.
	       Encodings  other	 than  UTF-8 are supported by using luit.  The
	       -lc option should be used  instead  of  -en  for	 systems  with
	       locale support.	This corresponds to the	locale resource.

       -fb font
	       This  option  specifies	a font to be used when displaying bold
	       text.  This font	must be	the same height	and width as the  nor-
	       mal  font.   If	only one of the	normal or bold fonts is	speci-
	       fied, it	will be	used as	the normal font	and the	bold font will
	       be  produced  by	 overstriking this font.  The default is to do
	       overstriking of the normal font.	 See also  the	discussion  of
	       boldFont	and boldMode resources.

       -fa pattern
	       This  option  sets  the	pattern	 for  fonts  selected from the
	       FreeType	library	if support for that library was	compiled  into
	       xterm.  This corresponds	to the faceName	resource.

       -fbb    This option indicates that xterm	should compare normal and bold
	       fonts bounding boxes to ensure they are compatible.

       +fbb    This option indicates that xterm	should not compare normal  and
	       bold fonts bounding boxes to ensure they	are compatible.

       -fbx    This  option  indicates	that  xterm should not assume that the
	       normal and bold fonts have VT100	line-drawing  characters.   If
	       any are missing,	xterm will draw	the characters directly.

       +fbx    This  option indicates that xterm should	assume that the	normal
	       and bold	fonts have VT100 line-drawing characters.

       -fi font
	       This option sets	the font for active icons if that feature  was
	       compiled	 into  xterm.  See also	the discussion of the iconFont
	       resource.

       -fs size
	       This option sets	the pointsize  for  fonts  selected  from  the
	       FreeType	 library if support for	that library was compiled into
	       xterm.  This corresponds	to the faceSize	resource.

       -fw font
	       This option specifies the font to be used for  displaying  wide
	       text.   By default, it will attempt to use a font twice as wide
	       as the font that	will be	used to	draw normal text.  If no  dou-
	       blewidth	 font  is  found, it will improvise, by	stretching the
	       normal font.  This corresponds to the wideFont resource.

       -fwb font
	       This option specifies the font to be used for  displaying  bold
	       wide  text.  By default,	it will	attempt	to use a font twice as
	       wide as the font	that will be used to draw bold	text.	If  no
	       doublewidth font	is found, it will improvise, by	stretching the
	       bold font.  This	corresponds to the wideBoldFont	resource.

       -fx font
	       This option specifies the font to be used  for  displaying  the
	       preedit string in the "OverTheSpot" input method.  See also the
	       discussion of the ximFont resource.

       -hc color
	       This option specifies the color to use for  the	background  of
	       selected	 or  otherwise	highlighted  text.   If	not specified,
	       reverse video is	used.

       -hf     This option indicates that HP Function Key escape codes	should
	       be generated for	function keys.

       +hf     This  option indicates that HP Function Key escape codes	should
	       not be generated	for function keys.

       -hold   Turn on the hold	resource, i.e.,	 xterm	will  not  immediately
	       destroy	its  window when the shell command completes.  It will
	       wait until you use the window manager to	destroy/kill the  win-
	       dow,  or	 if you	use the	menu entries that send a signal, e.g.,
	       HUP or KILL.

       +hold   Turn off	 the  hold  resource,  i.e.,  xterm  will  immediately
	       destroy its window when the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the pseudo-ter-
	       minal's sense of	the stty erase value.

       +ie     Turn off	the ptyInitialErase resource, i.e., set	the stty erase
	       value  using  the  kb string from the termcap entry as a	refer-
	       ence, if	available.

       -im     Turn on the useInsertMode resource.

       +im     Turn off	the useInsertMode resource.

       -into windowId
	       Given an	X window identifier (a decimal	integer),  xterm  will
	       reparent	 its  top-level	 shell widget to that window.  This is
	       used to embed xterm within other	applications.

       -j      This option indicates that  xterm  should  do  jump  scrolling.
	       Normally,  text	is  scrolled  one  line	at a time; this	option
	       allows xterm to move multiple lines at a	time so	that  it  does
	       not  fall as far	behind.	 Its use is strongly recommended since
	       it makes	xterm much faster when scanning	through	large  amounts
	       of text.	 The VT100 escape sequences for	enabling and disabling
	       smooth scroll as	well as	the ``VT Options'' menu	can be used to
	       turn this feature on or off.

       +j      This  option indicates that xterm should	not do jump scrolling.

       -l      Turn logging on.	 Normally logging is  not  supported,  due  to
	       security	 concerns.   Some  versions  of	xterm may have logging
	       enabled.	 The logfile is	written	to the	directory  from	 which
	       xterm is	invoked.  The filename is generated, of	the form

		    XtermLog.XXXXXX

	       or

		    Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX

	       depending on how	xterm was built.

       +l      Turn logging off.

       -lc     Turn  on	 support  of  various  encodings  according  to	users'
	       LC_CTYPE	locale setting,	i.e., LC_ALL, LC_CTYPE,	or LANG	 vari-
	       ables.  This is achieved	by turning on UTF-8 mode and by	invok-
	       ing luit	for conversion between	locale	encodings  and	UTF-8.
	       (luit  is  not  invoked	in UTF-8 locales.)  All	you need is an
	       iso10646-1 font regardless of your locale and  encoding.	  This
	       corresponds to the locale resource.

	       The  actual list	of encodings which are supported is determined
	       by luit.	 Consult the luit manual page for futher details.

       +lc     Turn off	support	of automatic selection	of  locale  encodings.
	       Conventional 8bit mode or, in UTF-8 locales or with -u8 option,
	       UTF-8 mode will be used.

       -lcc path
	       File name for the encoding converter from/to  locale  encodings
	       and  UTF-8  which  is  used with	-lc option or locale resource.
	       This corresponds	to the localeFilter resource.

       -leftbar
	       Force scrollbar to the left side	of VT100 screen.  This is  the
	       default,	unless you have	set the	rightScrollBar resource.

       -lf filename
	       Specify the log-filename.  See the -l option.

       -ls     This  option  indicates	that  the shell	that is	started	in the
	       xterm window will be a login shell (i.e., the  first  character
	       of  argv[0]  will  be  a	 dash, indicating to the shell that it
	       should read the user's .login or	.profile).

	       Note that this is incompatible with -e, since the login program
	       does not	provide	a way to specify the command to	run in the new
	       shell.  If you specify both, xterm uses -ls.

       +ls     This option indicates that the shell that is started should not
	       be a login shell	(i.e. it will be a normal ``subshell'').

       -mb     This option indicates that xterm	should ring a margin bell when
	       the user	types near the right end of a line.  This  option  can
	       be turned on and	off from the ``VT Options'' menu.

       +mb     This option indicates that margin bell should not be rung.

       -mc milliseconds
	       This  option  specifies	the  maximum  time between multi-click
	       selections.

       -mesg   Turn off	the messages resource, i.e., disallow write access  to
	       the terminal.

       +mesg   Turn  on	the messages resource, i.e., allow write access	to the
	       terminal.

       -ms color
	       This option specifies the color to be used for the pointer cur-
	       sor.  The default is to use the foreground color.

       -nb number
	       This  option  specifies the number of characters	from the right
	       end of a	line at	which the margin bell, if enabled, will	 ring.
	       The default is 10.

       -nul    This option disables the	display	of underlining.

       +nul    This option enables the display of underlining.

       -pc     This  option enables the	PC-style use of	bold colors (see bold-
	       Colors resource).

       +pc     This option disables the	PC-style use of	bold colors.

       -pob    This option indicates that the window should be raised whenever
	       a Control-G is received.

       +pob    This  option  indicates	that  the  window should not be	raised
	       whenever	a Control-G is received.

       -rightbar
	       Force scrollbar to the right side of VT100 screen.

       -rvc    This option disables the	display	 of  characters	 with  reverse
	       attribute as color.

       +rvc    This  option  enables  the  display  of characters with reverse
	       attribute as color.

       -rw     This  option  indicates	that  reverse-wraparound   should   be
	       allowed.	  This	allows the cursor to back up from the leftmost
	       column of one line to the  rightmost  column  of	 the  previous
	       line.  This is very useful for editing long shell command lines
	       and is encouraged.  This	option can be turned on	and  off  from
	       the ``VT	Options'' menu.

       +rw     This  option  indicates	that  reverse-wraparound should	not be
	       allowed.

       -s      This option indicates that  xterm  may  scroll  asynchronously,
	       meaning	that the screen	does not have to be kept completely up
	       to date while scrolling.	 This allows xterm to run faster  when
	       network	latencies  are	very high and is typically useful when
	       running across a	very large internet or many gateways.

       +s      This option indicates that xterm	should scroll synchronously.

       -samename
	       Does not	send title and icon  name  change  requests  when  the
	       request	would  have  no	effect:	the name is not	changed.  This
	       has the advantage of preventing flicker and the disadvantage of
	       requiring  an  extra  round  trip to the	server to find out the
	       previous	value.	In practice this should	never be a problem.

       +samename
	       Always send title and icon name change requests.

       -sb     This option indicates  that  some  number  of  lines  that  are
	       scrolled	 off  the top of the window should be saved and	that a
	       scrollbar should	be  displayed  so  that	 those	lines  can  be
	       viewed.	 This  option  may  be turned on and off from the ``VT
	       Options'' menu.

       +sb     This option indicates that a scrollbar should not be displayed.

       -sf     This option indicates that Sun Function Key escape codes	should
	       be generated for	function keys.

       +sf     This option indicates that the standard escape codes should  be
	       generated for function keys.

       -si     This  option indicates that output to a window should not auto-
	       matically reposition the	screen to the bottom of	the  scrolling
	       region.	 This  option  can  be turned on and off from the ``VT
	       Options'' menu.

       +si     This option indicates that output to a window should  cause  it
	       to scroll to the	bottom.

       -sk     This  option  indicates	that  pressing	a  key while using the
	       scrollbar to review previous lines of  text  should  cause  the
	       window  to be repositioned automatically	in the normal position
	       at the bottom of	the scroll region.

       +sk     This option indicates that  pressing  a	key  while  using  the
	       scrollbar should	not cause the window to	be repositioned.

       -sl number
	       This  option  specifies	the  number of lines to	save that have
	       been scrolled off the top of the	screen.	 The default is	64.

       -sm     This option, corresponding to the  sessionMgt  resource,	 indi-
	       cates that xterm	should set up session manager callbacks.

       +sm     This option indicates that xterm	should not set up session man-
	       ager callbacks.

       -sp     This option indicates that Sun/PC keyboard should  be  assumed,
	       providing  mapping  for	keypad `+' to `,', and CTRL-F1 to F13,
	       CTRL-F2 to F14, etc.

       +sp     This option indicates that the standard escape codes should  be
	       generated for keypad and	function keys.

       -t      This  option  indicates	that  xterm  should start in Tektronix
	       mode, rather than in VT102 mode.	  Switching  between  the  two
	       windows is done using the ``Options'' menus.

       +t      This option indicates that xterm	should start in	VT102 mode.

       -ti term_id
	       Specify	the  name used by xterm	to select the correct response
	       to terminal ID queries.	It also	specifies the emulation	level,
	       used  to	 determine  the	 type  of  response  to	 a  DA control
	       sequence.  Valid	values include vt52, vt100, vt101, vt102,  and
	       vt220  (the  "vt"  is  optional).   The	default	is vt100.  The
	       term_id argument	specifies the terminal ID to  use.   (This  is
	       the same	as the decTerminalID resource).

       -tm string
	       This  option  specifies	a  series of terminal setting keywords
	       followed	by the characters that should be bound to those	 func-
	       tions,	similar	 to  the  stty	program.   Allowable  keywords
	       include:	intr, quit, erase, kill, eof, eol, swtch, start, stop,
	       brk,  susp,  dsusp,  rprnt,  flush,  weras, and lnext.  Control
	       characters may be specified as ^char (e.g., ^c or  ^u)  and  ^?
	       may be used to indicate delete (127).

       -tn name
	       This  option  specifies the name	of the terminal	type to	be set
	       in the TERM environment	variable.   This  terminal  type  must
	       exist  in  the  termcap(5) database and should have li# and co#
	       entries.

       -u8     This option sets	the utf8 resource.  When utf8  is  set,	 xterm
	       interprets  incoming  data  as UTF-8.  This sets	wideChars as a
	       side-effect, but	UTF-8 mode set by this option prevents it from
	       being  turned  off.   If	 you  must turn	it on and off, use the
	       wideChars resource.  Note this option and the utf8 resource are
	       overridden  by  the  -lc	 and  -en options and locale resource.
	       Instead,	please use ``-lc'' option or ``locale: true'' resource
	       in UTF-8	locales	when your operating system supports locale, or
	       ``-en UTF-8'' option or ``locale: UTF-8''  resource  when  your
	       operating system	does not support locale.

       +u8     This option resets the utf8 resource.

       -ulc    This  option  disables the display of characters	with underline
	       attribute as color rather than with underlining.

       +ulc    This option enables the display of  characters  with  underline
	       attribute as color rather than with underlining.

       -ut     This option indicates that xterm	should not write a record into
	       the the system utmp log file.

       +ut     This option indicates that xterm	should write a record into the
	       system utmp log file.

       -vb     This  option  indicates that a visual bell is preferred over an
	       audible one.  Instead of	ringing	the terminal bell  whenever  a
	       Control-G is received, the window will be flashed.

       +vb     This option indicates that a visual bell	should not be used.

       -wc     This  option  sets  the	wideChars resource.  When wideChars is
	       set, xterm maintains internal structures	for 16-bit characters.
	       If  you do not set this resource	to ``true'', xterm will	ignore
	       the escape sequence which turns UTF-8 mode  on  and  off.   The
	       default is ``false''.

       +wc     This option resets the wideChars	resource.

       -wf     This  option indicates that xterm should	wait for the window to
	       be mapped the first time	before starting	the subprocess so that
	       the  initial  terminal  size settings and environment variables
	       are correct.  It	is the application's responsibility  to	 catch
	       subsequent terminal size	changes.

       +wf     This  option indicates that xterm show not wait before starting
	       the subprocess.

       -ziconbeep percent
	       Same as zIconBeep resource.  If	percent	 is  non-zero,	xterms
	       that  produce  output while iconified will cause	an XBell sound
	       at the given volume and have  "***"  prepended  to  their  icon
	       titles.	 Most  window managers will detect this	change immedi-
	       ately, showing you which	window has  the	 output.   (A  similar
	       feature was in x10 xterm.)

       -C      This  option  indicates that this window	should receive console
	       output.	This is	not supported on all systems.  To obtain  con-
	       sole  output,  you must be the owner of the console device, and
	       you must	have read and write permission for  it.	  If  you  are
	       running	X under	xdm on the console screen you may need to have
	       the session startup and reset programs  explicitly  change  the
	       ownership  of the console device	in order to get	this option to
	       work.

       -Sccn   This option allows xterm	to be used  as	an  input  and	output
	       channel	for  an	existing program and is	sometimes used in spe-
	       cialized	applications.  The option value	specifies the last few
	       letters	of the name of a pseudo-terminal to use	in slave mode,
	       plus the	number of  the	inherited  file	 descriptor.   If  the
	       option contains a ``/'' character, that delimits	the characters
	       used for	the pseudo-terminal name  from	the  file  descriptor.
	       Otherwise,  exactly two characters are used from	the option for
	       the pseudo-terminal name, the remainder is the file descriptor.
	       Examples:
		      -S123/45
		      -Sab34

       The  following  command	line  arguments	are provided for compatibility
       with older versions.  They may not be supported in the next release  as
       the  X Toolkit provides standard	options	that accomplish	the same task.

       %geom   This option specifies the preferred size	and  position  of  the
	       Tektronix window.  It is	shorthand for specifying the ``*tekGe-
	       ometry''	resource.

	#geom  This option specifies the preferred position of the  icon  win-
	       dow.   It  is  shorthand	 for  specifying the ``*iconGeometry''
	       resource.

       -T string
	       This option specifies the title for  xterm's  windows.	It  is
	       equivalent to -title.

       -n string
	       This option specifies the icon name for xterm's windows.	 It is
	       shorthand for specifying	the ``*iconName'' resource.  Note that
	       this  is	 not the same as the toolkit option -name (see below).
	       The default icon	name is	the application	name.

       -r      This option indicates that reverse video	should be simulated by
	       swapping	 the  foreground and background	colors.	 It is equiva-
	       lent to -rv.

       -w number
	       This option specifies the width in pixels of  the  border  sur-
	       rounding	 the window.  It is equivalent to -borderwidth or -bw.

       The following standard X	Toolkit	command	line  arguments	 are  commonly
       used with xterm:

       -bd color
	       This  option  specifies	the color to use for the border	of the
	       window.	The default is ``black.''

       -bg color
	       This option specifies the color to use for  the	background  of
	       the window.  The	default	is ``white.''

       -bw number
	       This  option  specifies	the width in pixels of the border sur-
	       rounding	the window.

       -display	display
	       This option specifies the X server to contact; see X(7x).

       -fg color
	       This option specifies the color to  use	for  displaying	 text.
	       The default is ``black.''

       -fn font
	       This option specifies the font to be used for displaying	normal
	       text.  The default is fixed.

       -geometry geometry
	       This option specifies the preferred size	and  position  of  the
	       VT102 window; see X(7x).

       -iconic This  option indicates that xterm should	ask the	window manager
	       to start	it as an icon rather than as the normal	window.

       -name name
	       This  option  specifies	the  application  name	 under	 which
	       resources  are  to  be  obtained,  rather than the default exe-
	       cutable file name.  Name	should	not  contain  ``.''  or	 ``*''
	       characters.

       -rv     This option indicates that reverse video	should be simulated by
	       swapping	the foreground and background colors.

       +rv     Disable the simulation of reverse video by swapping  foreground
	       and background colors.

       -title string
	       This  option  specifies	the  window title string, which	may be
	       displayed by window managers  if	 the  user  so	chooses.   The
	       default	title  is  the	command	 line  specified  after	the -e
	       option, if any, otherwise the application name.

       -xrm resourcestring
	       This option specifies a resource	string to be  used.   This  is
	       especially  useful for setting resources	that do	not have sepa-
	       rate command line options.

RESOURCES
       The program understands all of the core X Toolkit  resource  names  and
       classes as well as:

       backarrowKeyIsErase (class BackarrowKeyIsErase)
	       Tie   the  VTxxx	 backarrowKey  and  ptyInitialErase  resources
	       together	by setting the DECBKM state according to  whether  the
	       initial	value of stty erase is a backspace (8) or delete (127)
	       character.  The default is ``false'', which disables this  fea-
	       ture.

       hold (class Hold)
	       If true,	xterm will not immediately destroy its window when the
	       shell command completes.	 It will wait until you	use the	window
	       manager	to  destroy/kill  the  window,	or if you use the menu
	       entries that send a signal, e.g., HUP or	KILL.  You may	scroll
	       back,  select text, etc., to perform most graphical operations.
	       Resizing	the  display  will  lose  data,	 however,  since  this
	       involves	interaction with the shell which is no longer running.

       hpFunctionKeys (class HpFunctionKeys)
	       Specifies whether or not	HP Function Key	escape codes should be
	       generated   for	 function  keys	 instead  of  standard	escape
	       sequences.

       iconGeometry (class IconGeometry)
	       Specifies the preferred size and	position  of  the  application
	       when  iconified.	  It  is  not necessarily obeyed by all	window
	       managers.

       iconName	(class IconName)
	       Specifies the icon name.	 The default is	the application	 name.

       messages	(class Messages)
	       Specifies  whether write	access to the terminal is allowed ini-
	       tially.	See mesg(1).  The default is ``true''.

       ptyInitialErase (class PtyInitialErase)
	       If ``true'', xterm will use the pseudo-terminal's sense of  the
	       stty  erase value.  If ``false'', xterm will set	the stty erase
	       value to	match its own configuration, using the kb string  from
	       the  termcap  entry  as	a  reference, if available.  In	either
	       case, the result	is applied to the TERMCAP variable which xterm
	       sets.  The default is ``false''.

       sameName	(class SameName)
	       If  the value of	this resource is ``true'', xterm does not send
	       title and icon name change requests when	the request would have
	       no  effect: the name is not changed.  This has the advantage of
	       preventing flicker and the disadvantage of requiring  an	 extra
	       round  trip  to	the server to find out the previous value.  In
	       practice	this should  never  be	a  problem.   The  default  is
	       ``true''.

       sessionMgt (class SessionMgt)
	       If  the	value of this resource is ``true'', xterm sets up ses-
	       sion manager callbacks for XtNdieCallback and  XtNsaveCallback.
	       The default is ``true''.

       sunFunctionKeys (class SunFunctionKeys)
	       Specifies  whether  or not Sun Function Key escape codes	should
	       be generated for	 function  keys	 instead  of  standard	escape
	       sequences.

       sunKeyboard (class SunKeyboard)
	       Specifies  whether  or  not  Sun/PC  keyboard  layout should be
	       assumed rather than DEC VT220.  This causes the keypad  `+'  to
	       be mapped to `,'.  and CTRL F1-F12 to F11-F20, depending	on the
	       setting of the ctrlFKeys	resource.  so  xterm  emulates	a  DEC
	       VT220  more  accurately.	  Otherwise (the default, with sunKey-
	       board set to ``false''),	xterm uses PC-style bindings  for  the
	       function	keys and keypad.

       termName	(class TermName)
	       Specifies the terminal type name	to be set in the TERM environ-
	       ment variable.

       title (class Title)
	       Specifies a string that may be used by the window manager  when
	       displaying this application.

       ttyModes	(class TtyModes)
	       Specifies a string containing terminal setting keywords and the
	       characters to which they	 may  be  bound.   Allowable  keywords
	       include:	intr, quit, erase, kill, eof, eol, swtch, start, stop,
	       brk, susp, dsusp, rprnt,	flush, weras, lnext and	status.	  Con-
	       trol  characters	may be specified as ^char (e.g., ^c or ^u) and
	       ^? may be used to indicate delete  (127).   Use	^-  to	denote
	       undef.	Use \034 to represent ^\, since	a literal backslash in
	       an X resource escapes the next character.

	       This is very useful for overriding the  default	terminal  set-
	       tings  without  having  to  do  an  stty	every time an xterm is
	       started.	 Note, however,	that the stty program on a given  host
	       may use different keywords; xterm's table is builtin.

       useInsertMode (class UseInsertMode)
	       Force  use  of insert mode by adding appropriate	entries	to the
	       TERMCAP environment variable.  This is  useful  if  the	system
	       termcap is broken.  The default is ``false.''

       utmpInhibit (class UtmpInhibit)
	       Specifies  whether or not xterm should try to record the	user's
	       terminal	in the system utmp log file.

       waitForMap (class WaitForMap)
	       Specifies whether or not	xterm should wait for the initial win-
	       dow  map	 before	 starting  the	subprocess.   The  default  is
	       ``false.''

       zIconBeep (class	ZIconBeep)
	       Same as -ziconbeep command line argument.  If the value of this
	       resource	 is  non-zero, xterms that produce output while	iconi-
	       fied will cause an XBell	sound at the  given  volume  and  have
	       "***"  prepended	 to  their  icon titles.  Most window managers
	       will detect this	change immediately, showing you	 which	window
	       has the output.	(A similar feature was in x10 xterm.)

       The  following  resources  are  specified  as  part of the vt100	widget
       (class VT100):

       activeIcon (class ActiveIcon)
	       Specifies whether or not	active icon windows  are  to  be  used
	       when the	xterm window is	iconified, if this feature is compiled
	       into xterm.  The	active icon is a miniature  representation  of
	       the  content  of	 the  window  and  will	 update	as the content
	       changes.	 Not all window	managers necessarily support  applica-
	       tion  icon  windows.   Some  window  managers will allow	you to
	       enter keystrokes	into the active	icon window.  The  default  is
	       ``false.''

       allowSendEvents (class AllowSendEvents)
	       Specifies  whether or not synthetic key and button events (gen-
	       erated using the	X protocol SendEvent request) should be	inter-
	       preted or discarded.  The default is ``false'' meaning they are
	       discarded.  Note	that allowing such events creates a very large
	       security	hole.

       allowWindowOps (class AllowWindowOps)
	       Specifies whether extended window control sequences (as used in
	       dtterm) for should be allowed.

       answerbackString	(class AnswerbackString)
	       Specifies the string that xterm sends in	 response  to  an  ENQ
	       (control/E)  character  from  the host.	The default is a blank
	       string, i.e., ``''.  A hardware VT100 implements	 this  feature
	       as a setup option.

       alwaysHighlight (class AlwaysHighlight)
	       Specifies  whether  or  not xterm should	always display a high-
	       lighted text cursor.  By	default, a hollow text cursor is  dis-
	       played whenever the pointer moves out of	the window or the win-
	       dow loses the input focus.

       alwaysUseMods (class AlwaysUseMods)
	       Override	the numLock resource, telling xterm to use the Alt and
	       Meta  modifiers	as  to	construct  parameters for function key
	       sequences even if those modifiers appear	 in  the  translations
	       resource.

       appcursorDefault	(class AppcursorDefault)
	       If ``true,'' the	cursor keys are	initially in application mode.
	       The default is ``false.''

       appkeypadDefault	(class AppkeypadDefault)
	       If ``true,'' the	keypad keys are	initially in application mode.
	       The default is ``false.''

       autoWrap	(class AutoWrap)
	       Specifies  whether  or  not  auto-wraparound should be enabled.
	       The default is ``true.''

       awaitInput (class AwaitInput)
	       Specifies whether or not	the xterm uses a 50 millisecond	 time-
	       out  to	await  input (i.e., to support the Xaw3d arrow scroll-
	       bar).  The default is ``false.''

       backarrowKey (class BackarrowKey)
	       Specifies whether the backarrow key transmits a	backspace  (8)
	       or delete (127) character.  This	corresponds to the DECBKM con-
	       trol sequence.  The default (backspace) is ``true.''   Pressing
	       the control key toggles this behavior.

       background (class Background)
	       Specifies  the  color  to use for the background	of the window.
	       The default is ``white.''

       bellSuppressTime	(class BellSuppressTime)
	       Number of milliseconds after a  bell  command  is  sent	during
	       which additional	bells will be suppressed.  Default is 200.  If
	       set non-zero, additional	bells will also	 be  suppressed	 until
	       the  server  reports that processing of the first bell has been
	       completed; this feature is most useful with the visible bell.

       boldColors (class ColorMode)
	       Specifies whether to combine bold attribute  with  colors  like
	       the  IBM	 PC,  i.e., map	colors 0 through 7 to colors 8 through
	       15.  These normally are the brighter versions of	 the  first  8
	       colors, hence bold.  The	default	is ``true.''

       boldFont	(class BoldFont)
	       Specifies  the  name  of	 the bold font to use instead of over-
	       striking.

       boldMode	(class BoldMode)
	       This specifies whether or not  text  with  the  bold  attribute
	       should  be  overstruck  to  simulate bold fonts if the resolved
	       bold font is the	same as	the normal font.  It may be  desirable
	       to  disable  bold  fonts	 when color is being used for the bold
	       attribute.  Note	that xterm has one bold	font which you may set
	       explicitly.   It	 attempts  to  match a bold font for the other
	       font selections (font1 through font6).  If the normal and  bold
	       fonts are distinct, this	resource has no	effect.

       brokenSelections	(class BrokenSelections)
	       If  true,  xterm	in 8-bit mode will interpret STRING selections
	       as carrying text	in the current	locale's  encoding.   Normally
	       STRING  selections carry	ISO-8859-1 encoded text.  Setting this
	       resource	to ``true'' violates the ICCCM;	it  may,  however,  be
	       useful for interacting with some	broken X clients.  The default
	       is ``false.''

       c132 (class C132)
	       Specifies whether or not	 the  VT102  DECCOLM  escape  sequence
	       should be honored.  The default is ``false.''

       cutNewline (class CutNewline)
	       If ``false'', triple clicking to	select a line does not include
	       the Newline at the end of the line.  If ``true'',  the  Newline
	       is selected.  The default is ``true.''

       cutToBeginningOfLine (class CutToBeginningOfLine)
	       If  ``false'',  triple  clicking	 to select a line selects only
	       from the	current	word forward.  If ``true'', the	entire line is
	       selected.  The default is ``true.''

       cacheDoublesize (class CacheDoublesize)
	       Specifies  the  maximum	number of double-sized fonts which are
	       cached by xterm.	 The default (8) may be	too large for  some  X
	       terminals  with	limited	 memory.   Set this to zero to disable
	       doublesize fonts	altogether.

       charClass (class	CharClass)
	       Specifies comma-separated lists of character class bindings  of
	       the form	[low-]high:value.  These are used in determining which
	       sets of characters should be treated the	same  when  doing  cut
	       and paste.  See the section on specifying character classes.

       cjkWidth	(class CjkWidth)
	       Specifies  whether  xterm  should  follow  the traditional East
	       Asian width convention.	When turned on,	characters  with  East
	       Asian  Ambiguous	 (A) category in UTR 11	have a column width of
	       2.  You may have	to set this option to  ``true''	 if  you  have
	       some  old  East	Asian terminal based programs that assume that
	       line-drawing characters have a column width of 2.

       curses (class Curses)
	       Specifies whether or not	the last column	bug in more(1)	should
	       be worked around.  See the -cu option for details.  The default
	       is ``false.''

       colorAttrMode (class ColorMode)
	       Specifies whether ``colorBD'',  ``colorBL'',  ``colorUL'',  and
	       ``colorRV''  should  override  ANSI  colors.  If	not, these are
	       displayed only when no ANSI colors have been set	for the	corre-
	       sponding	position.  The default is ``false.''

       colorMode (class	ColorMode)
	       Specifies  whether  or not recognition of ANSI (ISO 6429) color
	       change escape sequences should  be  enabled.   The  default  is
	       ``true.''

       colorBDMode (class ColorMode)
	       Specifies  whether characters with the bold attribute should be
	       displayed in color or as	bold characters.   Note	 that  setting
	       colorMode off disables all colors, including bold.

       colorBLMode (class ColorMode)
	       Specifies whether characters with the blink attribute should be
	       displayed in color.  Note that setting colorMode	 off  disables
	       all colors, including this.

       colorRVMode (class ColorMode)
	       Specifies  whether characters with the reverse attribute	should
	       be displayed in color.  Note that setting  colorMode  off  dis-
	       ables all colors, including this.

       colorULMode (class ColorMode)
	       Specifies  whether  characters  with  the  underline  attribute
	       should be displayed in color or as underlined characters.  Note
	       that  setting  colorMode	 off  disables	all  colors, including
	       underlining.

       color0 (class Color0)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

       color7 (class Color7)
	       These specify the colors	 for  the  ISO	6429  extension.   The
	       defaults	 are,  respectively,  black,  red3,  green3,  yellow3,
	       blue3, magenta3,	cyan3, and  gray90.   The  default  shades  of
	       color  are  chosen  to  allow  the  colors  8-15	 to be used as
	       brighter	versions.

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

       color15 (class Color15)
	       These specify the colors	for the	ISO 6429 extension if the bold
	       attribute  is  also  enabled.  The default resource values are,
	       respectively, gray30, red, green, yellow, blue, magenta,	 cyan,
	       and white.

       color16 (class Color16)

       through

       color255	(class Color255)
	       These  specify  the  colors  for	 the 256-color extension.  The
	       default resource	values are for colors 16 through 231 to	make a
	       6x6x6  color  cube,  and	 colors	 232  through  255  to	make a
	       grayscale ramp.

       colorBD (class ColorBD)
	       This specifies the color	to use to display bold	characters  if
	       the ``colorBDMode'' resource is enabled.

       colorBL (class ColorBL)
	       This  specifies the color to use	to display blink characters if
	       the ``colorBLMode'' resource is enabled.

       colorRV (class ColorRV)
	       This specifies the color	to use to display  reverse  characters
	       if the ``colorRVMode'' resource is enabled.

       colorUL (class ColorUL)
	       This  specifies	the color to use to display underlined charac-
	       ters if the ``colorULMode'' resource is enabled.

       ctrlFKeys (class	CtrlFKeys)
	       In VT220	keyboard mode (see  sunKeyboard	 resource),  specifies
	       the  amount  by	which to shift F1-F12 given a control modifier
	       (CTRL).	This allows you	to generate key	symbols	for F10-F20 on
	       a  Sun/PC  keyboard.   The  default is ``10'', which means that
	       CTRL F1 generates the key symbol	for F11.

       cursorBlink (class CursorBlink)
	       Specifies whether to make the cursor  blink.   The  default  is
	       ``false.''

       cursorColor (class CursorColor)
	       Specifies the color to use for the text cursor.	The default is
	       ``black.''

       cursorOffTime (class CursorOffTime)
	       Specifies the duration of the "off" part	of  the	 cursor	 blink
	       cycle-time in milliseconds.  The	default	is 300.

       cursorOnTime (class CursorOnTime)
	       Specifies  the  duration	 of  the "on" part of the cursor blink
	       cycle-time, in milliseconds.  The default is 600.

       highlightColor (class HighlightColor)
	       Specifies the color to use for the background  of  selected  or
	       otherwise highlighted text.  If not specified, reverse video is
	       used.

       decTerminalID (class DecTerminalID)
	       Specifies the emulation	level  (100=VT100,  220=VT220,	etc.),
	       used  to	 determine  the	 type  of  response  to	 a  DA control
	       sequence.  The default is 100.

       deleteIsDEL (class DeleteIsDEL)
	       Specifies whether the Delete key	on the editing	keypad	should
	       send  DEL (127) or the VT220-style Remove escape	sequence.  The
	       default is ``false,'' for the latter.

       dynamicColors (class DynamicColors)
	       Specifies whether or not	 escape	 sequences  to	change	colors
	       assigned	to different attributes	are recognized.

       eightBitControl (class EightBitControl)
	       Specifies whether or not	control	sequences sent by the terminal
	       should  be  eight-bit  characters  or  escape  sequences.   The
	       default is ``false.''

       eightBitInput (class EightBitInput)
	       If  ``true'',  Meta characters input from the keyboard are pre-
	       sented as a single character with the  eighth  bit  turned  on.
	       The  terminal is	put into 8-bit mode.  If ``false'', Meta char-
	       acters are converted into a  two-character  sequence  with  the
	       character  itself  preceded  by	ESC.  The terminal is put into
	       7-bit mode.  The	metaSendsEscape	resource  may  override	 this.
	       The default is ``true.''

       eightBitOutput (class EightBitOutput)
	       Specifies  whether  or  not  eight-bit characters sent from the
	       host should be accepted as is or	stripped  when	printed.   The
	       default	is ``true,'' which means that they are accepted	as is.

       faceName	(class FaceName)
	       Specify the  pattern  for  fonts	 selected  from	 the  FreeType
	       library	if  support  for that library was compiled into	xterm.
	       There is	no default.  If	not specified, or if there is no match
	       for both	normal and bold	fonts, xterm uses the font and related
	       resources.

       faceSize	(class FaceSize)
	       Specify the pointsize for  fonts	 selected  from	 the  FreeType
	       library	if  support  for that library was compiled into	xterm.
	       The default is ``14.''

       font (class Font)
	       Specifies  the  name  of	 the  normal  font.   The  default  is
	       ``fixed.''

       font1 (class Font1)
	       Specifies the name of the first alternative font.

       font2 (class Font2)
	       Specifies the name of the second	alternative font.

       font3 (class Font3)
	       Specifies the name of the third alternative font.

       font4 (class Font4)
	       Specifies the name of the fourth	alternative font.

       font5 (class Font5)
	       Specifies the name of the fifth alternative font.

       font6 (class Font6)
	       Specifies the name of the sixth alternative font.

       fontDoublesize (class FontDoublesize)
	       Specifies  whether  xterm should	attempt	to use font scaling to
	       draw doublesize characters.  Some older font servers cannot  do
	       this  properly,	will  return  misleading  font	metrics.   The
	       default is ``true''.  If	disabled, xterm	will simulate  double-
	       size  characters	 by  drawing  normal  characters  with	spaces
	       between them.

       forceBoxChars (class Boolean)
	       Specifies whether xterm should assume the normal	and bold fonts
	       have  VT100  line-drawing characters.  If ``false'', xterm will
	       check for missing characters in the 1-31	cells and  make	 line-
	       drawing characters directly.  The default is ``false.''

       foreground (class Foreground)
	       Specifies  the  color to	use for	displaying text	in the window.
	       Setting the class name instead of the instance name is an  easy
	       way  to	have everything	that would normally appear in the text
	       color change color.  The	default	is ``black.''

       freeBoldBox (class Boolean)
	       Specifies whether xterm should assume the  bounding  boxes  for
	       normal and bold fonts are compatible.  If ``false'', xterm com-
	       pares them and will reject choices of bold fonts	 that  do  not
	       match  the  size	of the normal font.  The default is ``false'',
	       which means that	the comparison is performed.

       geometry	(class Geometry)
	       Specifies the preferred size and	position of the	VT102  window.

       highlightSelection (class HighlightSelection)
	       If ``false'', selecting with the	mouse highlights all positions
	       on the screen between the beginning of the  selection  and  the
	       current position.  If ``true'', xterm highlights	only the posi-
	       tions that contain text that can	be selected.  The  default  is
	       ``false.''

	       Depending  on  the  way	your applications write	to the screen,
	       there may be trailing blanks on a line.	Xterm stores  data  as
	       it  is  shown  on  the screen.  Erasing the display changes the
	       internal	state of each cell so it is not	considered a blank for
	       the  purpose of selection.  Blanks written since	the last erase
	       are selectable.	If you do not wish to have trailing blanks  in
	       a selection, use	the trimSelection resource.

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
	       Specifies  whether  to  work  around  a	bug in HP's xdb, which
	       ignores termcap and always sends	ESC F to  move	to  the	 lower
	       left  corner.   ``true''	 causes	 xterm to interpret ESC	F as a
	       request to move to the lower left corner	of  the	 screen.   The
	       default is ``false.''

       i18nSelections (class I18nSelections)
	       If false, xterm will never request the targets COMPOUND_TEXT or
	       TEXT.  The default is ``true.'' It may be set to	false in order
	       to work around ICCCM violations by other	X clients.

       iconBorderColor (class BorderColor)
	       Specifies  the  border color for	the active icon	window if this
	       feature is compiled into	xterm.	Not all	window	managers  will
	       make the	icon border visible.

       iconBorderWidth (class BorderWidth)
	       Specifies  the  border width for	the active icon	window if this
	       feature is compiled into	xterm.	The default is 0 (no  border).
	       Not all window managers will make the border visible.

       iconFont	(class IconFont)
	       Specifies  the  font  for  the miniature	active icon window, if
	       this feature is compiled	into xterm.  The default is "nil2".

       internalBorder (class BorderWidth)
	       Specifies the number of pixels between the characters  and  the
	       window border.  The default is 2.

       jumpScroll (class JumpScroll)
	       Specifies  whether  or  not  jump  scroll  should be used.  The
	       default is ``true.''

       keyboardDialect (class KeyboardDialect)
	       Specifies the initial keyboard dialect, as well as the  default
	       value  when the terminal	is reset.  The value given is the same
	       as the final character in the control  sequences	 which	change
	       character  sets.	 The default is	``B'', which corresponds to US
	       ASCII.

       limitResize (class LimitResize)
	       Limits resizing of the screen via control sequence to  a	 given
	       multiple	of the display dimensions.  The	default	is ``1''.

       locale (class Locale)
	       Specifies  how to use luit, an encoding converter between UTF-8
	       and locale encodings.  If this is ``true'', xterm will use  the
	       encoding	specified by the users'	LC_CTYPE locale	(i.e., LC_ALL,
	       LC_CTYPE, or LANG variables) as far as possible.	 This is real-
	       ized  by	 always	 enabling UTF-8	mode and invoking luit in non-
	       UTF-8 locales.  If this is ``medium'', xterm will follow	users'
	       LC_CTYPE	 locale	 only for UTF-8, east Asian, and Thai locales,
	       where the encodings were	not  supported	by  conventional  8bit
	       mode  with  changing  fonts.  For other locales,	xterm will use
	       conventional 8bit mode.	If this	is ``no'', xterm will use con-
	       ventional 8bit mode or UTF-8 mode according to utf8 resource or
	       -u8  option.   Any  other   value   such	  as   ``UTF-8''   and
	       ``ISO8859-2'' will be assumed to	be an encoding name; luit will
	       be invoked to support the encoding.  The	actual	list  of  sup-
	       ported encodings	depends	on luit.  The default is ``medium''.

       localeFilter (class LocaleFilter)
	       Specifies  the  file  name  for	the encoding converter from/to
	       locale encodings	and UTF-8 which	is used	with the -lc option or
	       locale  resource.   The	help  message shown by ``xterm -help''
	       lists the default value,	which depends on your system  configu-
	       ration.

       loginShell (class LoginShell)
	       Specifies  whether  or  not  the	 shell to be run in the	window
	       should be started as a login shell.  The	default	is  ``false.''

       marginBell (class MarginBell)
	       Specifies  whether  or not the bell should be run when the user
	       types near the right margin.  The default is ``false.''

       metaSendsEscape (class MetaSendsEscape)
	       If ``true'', Meta characters are	converted into a two-character
	       sequence	 with  the  character  itself  preceded	 by ESC.  This
	       applies as well to function key control sequences, unless xterm
	       sees that Meta is used in your key translations.	 If ``false'',
	       Meta characters input from the keyboard are  handled  according
	       to the eightBitInput resource.  The default is ``false.''

       modifyCursorKeys	(class ModifyCursorKeys)
	       Tells  how  to  handle the special case where control-, shift-,
	       alt- or meta-modifiers are used	to  add	 a  parameter  to  the
	       escape  sequence	 returned by a cursor-key.  Set	it to 0	to use
	       the old/obsolete	behavior.  Set it  to  1  to  prefix  modified
	       sequences  with	CSI.   Set it to 2 to force the	modifier to be
	       the second parameter.  Set it to	3 to mark the sequence with  a
	       '>' to hint that	it is private.	The default is ``2''.

       multiClickTime (class MultiClickTime)
	       Specifies  the maximum time in milliseconds between multi-click
	       select events.  The default is 250 milliseconds.

       multiScroll (class MultiScroll)
	       Specifies  whether  or  not  scrolling  should  be  done	 asyn-
	       chronously.  The	default	is ``false.''

       nMarginBell (class Column)
	       Specifies  the  number  of  characters from the right margin at
	       which the margin	bell should be rung, when enabled.

       numLock (class NumLock)
	       If ``true'', xterm checks if NumLock is used as a modifier (see
	       xmodmap(1)).   If  so,  this  modifier  is used to simplify the
	       logic when implementing special	NumLock	 for  the  sunKeyboard
	       resource.   Also	 (when sunKeyboard is false), similar logic is
	       used to find the	modifier associated with the  left  and	 right
	       Alt keys.  The default is ``true.''

       oldXtermFKeys (class OldXtermFKeys)
	       If  ``true'',  xterm  will  use old-style control sequences for
	       function	keys F1	to F4, for  compatibility  with	 X  Consortium
	       xterm.	Otherwise,  it	uses  the VT100-style codes for	PF1 to
	       PF4.  The default is ``false.''

       pointerColor (class PointerColor)
	       Specifies the foreground	color of the pointer.  The default  is
	       ``XtDefaultForeground.''

       pointerColorBackground (class PointerColorBackground)
	       Specifies  the background color of the pointer.	The default is
	       ``XtDefaultBackground.''

       pointerShape (class Cursor)
	       Specifies the name of the shape of the pointer.	The default is
	       ``xterm.''

       popOnBell (class	PopOnBell)
	       Specifies whether the window whould be raised when Control-G is
	       received.  The default is ``false.''

       printAttributes (class PrintAttributes)
	       Specifies whether to print graphic attributes  along  with  the
	       text.   A  real	DEC  VTxxx  terminal will print	the underline,
	       highlighting codes but your printer may not  handle  these.   A
	       ``0''  disables	the attributes.	 A ``1'' prints	the normal set
	       of  attributes  (bold,  underline,  inverse   and   blink)   as
	       VT100-style  control  sequences.	  A  ``2''  prints  ANSI color
	       attributes as well.  The	default	is ``1.''

       printerAutoClose	(class PrinterAutoClose)
	       If ``true'', xterm will close the printer  (a  pipe)  when  the
	       application switches the	printer	offline	with a Media Copy com-
	       mand.  The default is ``false.''

       printerCommand (class PrinterCommand)
	       Specifies a shell command to which xterm	will open a pipe  when
	       the first MC (Media Copy) command is initiated.	The default is
	       ``lpr.''	 If the	resource value is given	as a blank string, the
	       printer is disabled.

       printerControlMode (class PrinterControlMode)
	       Specifies  the printer control mode.  A ``1'' selects autoprint
	       mode, which causes xterm	to print a line	from the  screen  when
	       you  move  the cursor off that line with	a line feed, form feed
	       or vertical tab character, or an	 autowrap  occurs.   Autoprint
	       mode  is	overridden by printer controller mode (a ``2''), which
	       causes all of the output	to be directed to  the	printer.   The
	       default is ``0.''

       printerExtent (class PrinterExtent)
	       Controls	 whether  a  print page	function will print the	entire
	       page (true), or only the	the portion within the scrolling  mar-
	       gins (false).  The default is ``false.''

       printerFormFeed (class PrinterFormFeed)
	       Controls	 whether a form	feed is	sent to	the printer at the end
	       of a print page function.  The default is ``false.''

       resizeGravity (class ResizeGravity)
	       Affects the behavior when the window is resized to be taller or
	       shorter.	  NorthWest specifies that the top line	of text	on the
	       screen stay fixed.  If the window is made  shorter,  lines  are
	       dropped	from  the  bottom; if the window is made taller, blank
	       lines are added at the bottom.  This  is	 compatible  with  the
	       behavior	 in  R4.   SouthWest  (the default) specifies that the
	       bottom line of text on the screen stay fixed.  If the window is
	       made  taller, additional	saved lines will be scrolled down onto
	       the screen; if the  window  is  made  shorter,  lines  will  be
	       scrolled	 off  the  top	of the screen, and the top saved lines
	       will be dropped.

       reverseVideo (class ReverseVideo)
	       Specifies whether or not	reverse	 video	should	be  simulated.
	       The default is ``false.''

       reverseWrap (class ReverseWrap)
	       Specifies  whether or not reverse-wraparound should be enabled.
	       The default is ``false.''

       rightScrollBar (class RightScrollBar)
	       Specifies whether or not	the scrollbar should be	 displayed  on
	       the right rather	than the left.	The default is ``false.''

       saveLines (class	SaveLines)
	       Specifies  the  number  of  lines to save beyond	the top	of the
	       screen when a scrollbar is turned on.  The default is 64.

       scrollBar (class	ScrollBar)
	       Specifies whether or not	the  scrollbar	should	be  displayed.
	       The default is ``false.''

       scrollKey (class	ScrollCond)
	       Specifies  whether  or  not pressing a key should automatically
	       cause the scrollbar to  go  to  the  bottom  of	the  scrolling
	       region.	The default is ``false.''

       scrollLines (class ScrollLines)
	       Specifies  the number of	lines that the scroll-back and scroll-
	       forw actions should use as a default.  The default value	is  1.

       scrollTtyOutput (class ScrollCond)
	       Specifies whether or not	output to the terminal should automat-
	       ically cause the	scrollbar to go	to the bottom of the scrolling
	       region.	The default is ``true.''

       shiftFonts (class ShiftFonts)
	       Specifies  whether  to  enable the actions larger-vt-font() and
	       smaller-vt-font(), which	are  normally  bound  to  the  shifted
	       KP_Add and KP_Subtract.	The default is ``true.''

       signalInhibit (class SignalInhibit)
	       Specifies  whether  or  not the entries in the ``Main Options''
	       menu for	sending	signals	to xterm should	 be  disallowed.   The
	       default is ``false.''

       tekGeometry (class Geometry)
	       Specifies the preferred size and	position of the	Tektronix win-
	       dow.

       tekInhibit (class TekInhibit)
	       Specifies whether or not	the escape sequence to enter Tektronix
	       mode should be ignored.	The default is ``false.''

       tekSmall	(class TekSmall)
	       Specifies whether or not	the Tektronix mode window should start
	       in its smallest size if no explicit geometry is given.  This is
	       useful  when running xterm on displays with small screens.  The
	       default is ``false.''

       tekStartup (class TekStartup)
	       Specifies whether or not	xterm should  start  up	 in  Tektronix
	       mode.  The default is ``false.''

       titeInhibit (class TiteInhibit)
	       Specifies  whether or not xterm should remove ti	and te termcap
	       entries (used to	switch between alternate screens on startup of
	       many  screen-oriented  programs)	 from  the TERMCAP string.  If
	       set, xterm also ignores the escape sequence to  switch  to  the
	       alternate  screen.  Xterm supports terminfo in a	different way,
	       supporting composite control sequences (also known  as  private
	       modes)  1047,  1048  and	1049 which have	the same effect	as the
	       original	47 control sequence.

       tiXtraScroll (class TiXtraScroll)
	       Specifies whether xterm should scroll to	a new page  when  pro-
	       cessing	the ti termcap entry, i.e., the	private	modes 47, 1047
	       or 1049.	 This is only in effect	if  titeInhibit	 is  ``true'',
	       because	the  intent  of	this option is to provide a picture of
	       the full-screen application's display on	the scrollback without
	       wiping  out the text that would be shown	before the application
	       was initialized.	 The default for this resource is ``false.''

       translations (class Translations)
	       Specifies the key and button bindings  for  menus,  selections,
	       ``programmed strings,'' etc.  See ACTIONS below.

       trimSelection (class TrimSelection)
	       If  you	set  highlightSelection, you can see the text which is
	       selected, including any trailing	spaces.	 Clearing  the	screen
	       (or  a  line)  resets it	to a state containing no spaces.  Some
	       lines may contain trailing spaces when  an  application	writes
	       them  to	 the screen.  However, you may not wish	to paste lines
	       with trailing spaces.  If this resource	is  true,  xterm  will
	       trim  trailing spaces from text which is	selected.  It does not
	       affect spaces which result in a wrapped line, nor will it  trim
	       the  trailing  newline  from  your  selection.	The default is
	       ``false.''

       underLine (class	UnderLine)
	       This specifies whether or not text with the underline attribute
	       should be underlined.  It may be	desirable to disable underlin-
	       ing when	color is being used for	the underline attribute.

       utf8 (class Utf8)
	       This specifies whether xterm will run in	UTF-8  mode.   If  you
	       set  this resource, xterm also sets the wideChars resource as a
	       side-effect.  When set via a resource, xterm cannot be switched
	       via  control sequences out of UTF-8 mode.  The default is ``0''
	       (off).  Any other value will  turn  on  UTF-8  mode.   See  the
	       locale resource for non-UTF-8 locales.

       veryBoldColors (class ColorMode)
	       Specifies whether to combine video attributes with colors spec-
	       ified by	colorBD, colorBL and colorUL.  The resource  value  is
	       the  sum	 of  values for	each attribute:	2 for underline, 4 for
	       bold and	8 for blink.  The default is ``0.''

       visualBell (class VisualBell)
	       Specifies whether or not	a visible bell (i.e., flashing)	should
	       be  used	instead	of an audible bell when	Control-G is received.
	       The default is ``false.''

       vt100Graphics (class VT100Graphics)
	       This specifies whether xterm will interpret VT100 graphic char-
	       acter  escape  sequences	 while	in UTF-8 mode.	The default is
	       ``true'', to provide support for	various	legacy applications.

       wideBoldFont (class WideBoldFont)
	       This option specifies the font to be used for  displaying  bold
	       wide  text.  By default,	it will	attempt	to use a font twice as
	       wide as the font	that will be used to draw bold	text.	If  no
	       doublewidth font	is found, it will improvise, by	stretching the
	       bold font.

       wideChars (class	WideChars)
	       Specifies if xterm should respond  to  control  sequences  that
	       process 16-bit characters.

       wideFont	(class WideFont)
	       This  option  specifies the font	to be used for displaying wide
	       text.  By default, it will attempt to use a font	twice as  wide
	       as  the font that will be used to draw normal text.  If no dou-
	       blewidth	font is	found, it will improvise,  by  stretching  the
	       normal font.

       ximFont (class XimFont)
	       This  option  specifies	the font to be used for	displaying the
	       preedit string in the "OverTheSpot" input method.

	       In "OverTheSpot"	 preedit  type,	 the  preedit  (preconversion)
	       string  is  displayed at	the position of	the cursor.  It	is the
	       XIM server's responsibility to display the preedit string.  The
	       XIM  client  must inform	the XIM	server of the cursor position.
	       For best	results, the preedit string must be displayed  with  a
	       proper  font.   Therefore,  xterm informs the XIM server	of the
	       proper font.  The font is be supplied  by  a  "fontset",	 whose
	       default	value  is "*".	This matches every font, the X library
	       automatically chooses fonts with	proper charsets.  The  ximFont
	       resource	is provided to override	this default font setting.

       The  following  resources  are  specified as part of the	tek4014	widget
       (class Tek4014):

       font2 (class Font)
	       Specifies font number 2 to use in the Tektronix window.

       ginTerminator (class GinTerminator)
	       Specifies what character(s) should follow a GIN report or  sta-
	       tus  report.   The  possibilities  are ``none,''	which sends no
	       terminating  characters,	 ``CRonly,''  which  sends   CR,   and
	       ``CR&EOT,''  which  sends  both	CR  and	 EOT.	The default is
	       ``none.''

       height (class Height)
	       Specifies the height of the Tektronix window in pixels.

       initialFont (class InitialFont)

POINTER	USAGE
       Once the	VT102 window is	created, xterm allows you to select  text  and
       copy it within the same or other	windows.

       The  selection  functions are invoked when the pointer buttons are used
       with no modifiers, and when they	are used with the ``shift'' key.   The
       assignment  of the functions described below to keys and	buttons	may be
       changed through the resource database; see ACTIONS below.

       Pointer button one (usually left) is used to save  text	into  the  cut
       buffer.	 Move  the  cursor to beginning	of the text, and then hold the
       button down while moving	the cursor  to	the  end  of  the  region  and
       releasing the button.  The selected text	is highlighted and is saved in
       the global cut buffer and made the PRIMARY selection when the button is
       released.   Double-clicking  selects by words.  Triple-clicking selects
       by lines.  Quadruple-clicking goes back to characters, etc.   Multiple-
       click  is  determined by	the time from button up	to button down,	so you
       can change the selection	unit in	the middle of  a  selection.   Logical
       words  and lines	selected by double- or triple-clicking may wrap	across
       more than one screen line if lines were wrapped by xterm	itself	rather
       than by the application running in the window.  If the key/button bind-
       ings specify that an X selection	is to be made, xterm  will  leave  the
       selected	text highlighted for as	long as	it is the selection owner.

       Pointer	button two (usually middle) `types' (pastes) the text from the
       PRIMARY selection, if any, otherwise from the cut buffer, inserting  it
       as keyboard input.

       Pointer	button	three  (usually	 right)	extends	the current selection.
       (Without	loss of	generality, you	can swap ``right'' and ``left''	every-
       where  in  the rest of this paragraph.)	If pressed while closer	to the
       right edge of the selection than	the  left,  it	extends/contracts  the
       right  edge  of	the selection.	If you contract	the selection past the
       left edge of the	selection, xterm assumes you  really  meant  the  left
       edge,  restores the original selection, then extends/contracts the left
       edge of the selection.  Extension starts	in  the	 selection  unit  mode
       that  the  last selection or extension was performed in;	you can	multi-
       ple-click to cycle through them.

       By cutting and pasting pieces of	text without trailing new  lines,  you
       can  take text from several places in different windows and form	a com-
       mand to the shell, for example, or  take	 output	 from  a  program  and
       insert  it into your favorite editor.  Since the	cut buffer is globally
       shared among different applications, you	should regard it as  a	`file'
       whose contents you know.	 The terminal emulator and other text programs
       should be treating it as	if it were a text  file,  i.e.,	 the  text  is
       delimited by new	lines.

       The  scroll  region  displays the position and amount of	text currently
       showing in the window (highlighted) relative  to	 the  amount  of  text
       actually	saved.	As more	text is	saved (up to the maximum), the size of
       the highlighted area decreases.

       Clicking	button one with	the pointer in the  scroll  region  moves  the
       adjacent	line to	the top	of the display window.

       Clicking	 button	three moves the	top line of the	display	window down to
       the pointer position.

       Clicking	button two moves the display to	a position in the  saved  text
       that corresponds	to the pointer's position in the scrollbar.

       Unlike  the VT102 window, the Tektronix window does not allow the copy-
       ing of text.  It	does allow Tektronix GIN mode, and in  this  mode  the
       cursor  will  change  from  an arrow to a cross.	 Pressing any key will
       send that key and the current coordinate	of the cross cursor.  Pressing
       button  one,  two,  or three will return	the letters `l', `m', and `r',
       respectively.  If the `shift' key is pressed when a pointer  button  is
       pressed,	the corresponding upper	case letter is sent.  To distinguish a
       pointer button from a key, the high bit of the character	 is  set  (but
       this  is	 bit is	normally stripped unless the terminal mode is RAW; see
       tty(4) for details).

MENUS
       Xterm has four menus, named mainMenu, vtMenu,  fontMenu,	 and  tekMenu.
       Each  menu  pops	 up  under  the	correct	combinations of	key and	button
       presses.	 Most menus are	divided	into two section, separated by a hori-
       zontal  line.   The  top	 portion  contains  various  modes that	can be
       altered.	 A check mark appears next to a	mode that is currently active.
       Selecting  one of these modes toggles its state.	 The bottom portion of
       the menu	are command entries; selecting one of these performs the indi-
       cated function.

       The  xterm menu pops up when the	``control'' key	and pointer button one
       are pressed in a	window.	 The mainMenu contains	items  that  apply  to
       both  the  VT102	and Tektronix windows.	The Secure Keyboard mode is be
       used when typing	in passwords or	other sensitive	data  in  an  unsecure
       environment;  see  SECURITY below.  Notable entries in the command sec-
       tion of the menu	are the	Continue, Suspend, Interrupt,  Hangup,	Termi-
       nate and	Kill which sends the SIGCONT, SIGTSTP, SIGINT, SIGHUP, SIGTERM
       and SIGKILL signals, respectively, to the process group of the  process
       running	under  xterm  (usually	the  shell).  The Continue function is
       especially useful if the	user has accidentally typed CTRL-Z, suspending
       the process.

       The  vtMenu sets	various	modes in the VT102 emulation, and is popped up
       when the	``control'' key	and pointer button  two	 are  pressed  in  the
       VT102  window.	In  the	 command  section of this menu,	the soft reset
       entry will reset	scroll regions.	 This can be convenient	when some pro-
       gram  has left the scroll regions set incorrectly (often	a problem when
       using VMS or TOPS-20).  The full	reset entry  will  clear  the  screen,
       reset  tabs  to every eight columns, and	reset the terminal modes (such
       as wrap and smooth scroll) to their initial states just after xterm has
       finished	processing the command line options.

       The  fontMenu  sets  the	font used in the VT102 window.	In addition to
       the default font	and  a	number	of  alternatives  that	are  set  with
       resources,  the	menu  offers  the  font	last specified by the Set Font
       escape sequence (see the	document Xterm Control Sequences) and the cur-
       rent selection as a font	name (if the PRIMARY selection is owned).

       The  tekMenu  sets  various  modes  in  the Tektronix emulation,	and is
       popped up when the ``control'' key and pointer button two  are  pressed
       in the Tektronix	window.	 The current font size is checked in the modes
       section of the menu.  The PAGE entry in the command section clears  the
       Tektronix window.

SECURITY
       X  environments	differ in their	security consciousness.	 Most servers,
       run under xdm, are capable of using a  ``magic  cookie''	 authorization
       scheme that can provide a reasonable level of security for many people.
       If your server is only using a host-based mechanism to  control	access
       to  the server (see xhost(1)), then if you enable access	for a host and
       other users are also permitted to run clients on	that same host,	 there
       is  every possibility that someone can run an application that will use
       the basic services of the X  protocol  to  snoop	 on  your  activities,
       potentially  capturing  a transcript of everything you type at the key-
       board.  This is of particular concern when you want to type in a	 pass-
       word  or	other sensitive	data.  The best	solution to this problem is to
       use a better authorization mechanism that  host-based  control,	but  a
       simple mechanism	exists for protecting keyboard input in	xterm.

       The  xterm  menu	 (see  MENUS  above)  contains a Secure	Keyboard entry
       which, when enabled, ensures that all keyboard input is	directed  only
       to  xterm  (using the GrabKeyboard protocol request).  When an applica-
       tion prompts you	for a password (or  other  sensitive  data),  you  can
       enable  Secure Keyboard using the menu, type in the data, and then dis-
       able Secure Keyboard using the menu again.  Only	one X client at	a time
       can  secure the keyboard, so when you attempt to	enable Secure Keyboard
       it may fail.  In	this case, the bell will sound.	 If  the  Secure  Key-
       board  succeeds,	the foreground and background colors will be exchanged
       (as if you selected the Reverse Video entry in the  Modes  menu);  they
       will  be	 exchanged  again when you exit	secure mode.  If the colors do
       not switch, then	you should be  very  suspicious	 that  you  are	 being
       spoofed.	  If  the application you are running displays a prompt	before
       asking for the password,	it is safest to	enter secure mode  before  the
       prompt  gets displayed, and to make sure	that the prompt	gets displayed
       correctly (in the new colors), to minimize the probability of spoofing.
       You  can	 also  bring up	the menu again and make	sure that a check mark
       appears next to the entry.

       Secure Keyboard mode will be disabled automatically if your xterm  win-
       dow  becomes  iconified	(or  otherwise unmapped), or if	you start up a
       reparenting window manager (that	places a title bar or other decoration
       around  the  window) while in Secure Keyboard mode.  (This is a feature
       of the X	protocol not easily overcome.)	When this happens,  the	 fore-
       ground  and  background	colors will be switched	back and the bell will
       sound in	warning.

CHARACTER CLASSES
       Clicking	the middle mouse button	twice in rapid succession  will	 cause
       all  characters of the same class (e.g.,	letters, white space, punctua-
       tion) to	be selected.  Since different people  have  different  prefer-
       ences  for  what	 should	 be selected (for example, should filenames be
       selected	as a whole or only the separate	subnames), the default mapping
       can  be	overridden  through the	use of the charClass (class CharClass)
       resource.

       This resource is	a series of comma-separated of range:value pairs.  The
       range is	either a single	number or low-high in the range	of 0 to	65535,
       corresponding to	the code for the character or characters  to  be  set.
       The  value  is arbitrary, although the default table uses the character
       number of the first character occurring in the set.  When not in	 UTF-8
       mode, only the first 256	bytes of this table will be used.

       The default table starts	as follows -

	       static int charClass[256] = {

		   32,	 1,   1,   1,	1,   1,	  1,   1,

		    1,	32,   1,   1,	1,   1,	  1,   1,

		   32,	33,  34,  35,  36,  37,	 38,  39,

		   40,	41,  42,  43,  44,  45,	 46,  47,

		   64,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  91,  92,  93,	 94,  48,

		   96,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		    1,	 1,   1,   1,	1,   1,	  1,   1,

		    1,	 1,   1,   1,	1,   1,	  1,   1,

		  160, 161, 162, 163, 164, 165,	166, 167,

		  168, 169, 170, 171, 172, 173,	174, 175,

		  176, 177, 178, 179, 180, 181,	182, 183,

		  184, 185, 186, 187, 188, 189,	190, 191,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48, 215,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48,  48,

		   48,	48,  48,  48,  48,  48,	 48, 247,

		   48,	48,  48,  48,  48,  48,	 48,  48};

       For  example,  the string ``33:48,37:48,45-47:48,64:48''	indicates that
       the exclamation mark, percent sign, dash, period, slash,	and  ampersand
       characters  should  be  treated the same	way as characters and numbers.
       This is useful for cutting and pasting electronic mailing addresses and
       filenames.

ACTIONS
       It  is  possible	 to  rebind  keys  (or sequences of keys) to arbitrary
       strings for input, by  changing	the  translations  for	the  vt100  or
       tek4014	widgets.   Changing the	translations for events	other than key
       and button events is not	expected, and will cause unpredictable	behav-
       ior.   The following actions are	provided for using within the vt100 or
       tek4014 translations resources:

       allow-send-events(on/off/toggle)
	       This action set or toggles the allowSendEvents resource and  is
	       also invoked by the allowsends entry in mainMenu.

       bell([percent])
	       This action rings the keyboard bell at the specified percentage
	       above or	below the base volume.

       clear-saved-lines()
	       This action does	hard-reset() (see below) and also  clears  the
	       history	of  lines saved	off the	top of the screen.  It is also
	       invoked from the	clearsavedlines	entry in vtMenu.   The	effect
	       is identical to a hardware reset	(RIS) control sequence.

       create-menu(m/v/f/t)
	       This  action  creates one of the	menus used by xterm, if	it has
	       not been	previously created.  The parameter values are the menu
	       names: mainMenu,	vtMenu,	fontMenu, tekMenu, respectively.

       deiconify()
	       Changes the window state	back to	normal,	if it was iconified.

       delete-is-del()
	       This action toggles the state of	the deleteIsDEL	resource.

       dired-button()
	       Handles	a button event (other than press and release) by echo-
	       ing the event's position	(i.e., character line and  column)  in
	       the following format:

		       ^X ESC G	<line+'	'> <col+' '>

       iconify()
	       Iconifies the window.

       hard-reset()
	       This action resets the scrolling	region,	tabs, window size, and
	       cursor keys and clears the screen.  It is also invoked from the
	       hardreset entry in vtMenu.

       ignore()
	       This  action  ignores  the event	but checks for special pointer
	       position	escape sequences.

       insert()
	       This action inserts the character or string associated with the
	       key that	was pressed.

       insert-eight-bit()
	       This  action inserts an eight-bit (Meta)	version	of the charac-
	       ter or string associated	with the key that  was	pressed.   The
	       exact  action  depends  on the value of the metaSendsEscape and
	       the eightBitInput resources.

       insert-selection(sourcename [, ...])
	       This action inserts the string found in the selection  or  cut-
	       buffer  indicated  by  sourcename.   Sources are	checked	in the
	       order given (case is significant) until	one  is	 found.	  Com-
	       monly-used  selections  include:	 PRIMARY, SECONDARY, and CLIP-
	       BOARD.  Cut buffers are	typically  named  CUT_BUFFER0  through
	       CUT_BUFFER7.

       insert-seven-bit()
	       This action is a	synonym	for insert()

       interpret(control-sequence)
	       Interpret  the  given  control  sequence	locally, i.e., without
	       passing it to the host.	This works by  inserting  the  control
	       sequence	 at  the front of the input buffer.  Use "\" to	escape
	       octal digits in the string.  Xt does not	allow  you  to	put  a
	       null character (i.e., "\000") in	the string.

       keymap(name)
	       This  action  dynamically defines a new translation table whose
	       resource	name is	name with the suffix Keymap (case is  signifi-
	       cant).	The name None restores the original translation	table.

       larger-vt-font()
	       Set the font to the next	larger one, based on the  font	dimen-
	       sions.  See also	set-vt-font().

       maximize()
	       Resizes the window to fill the screen.

       meta-sends-escape()
	       This  action toggles the	state of the metaSendsEscape resource.

       popup-menu(menuname)
	       This action displays the	specified  popup  menu.	  Valid	 names
	       (case is	significant) include:  mainMenu, vtMenu, fontMenu, and
	       tekMenu.

       print() This action prints the window and is also invoked by the	 print
	       entry in	mainMenu.

       print-redir()
	       This  action  toggles  the  printerControlMode between 0	and 2.
	       The corresponding popup menu entry is useful for	switching  the
	       printer off if you happen to change your	mind after deciding to
	       print random binary files on the	terminal.

       quit()  This action sends a SIGHUP to the subprogram and	exits.	It  is
	       also invoked by the quit	entry in mainMenu.

       redraw()
	       This  action  redraws  the  window  and	is also	invoked	by the
	       redraw entry in mainMenu.

       restore()
	       Restores	the window to the size before it was last maximized.

       scroll-back(count [,units [,mouse] ])
	       This action scrolls the text window backward so that text  that
	       had  previously scrolled	off the	top of the screen is now visi-
	       ble.  The count argument	indicates the number of	 units	(which
	       may  be page, halfpage, pixel, or line) by which	to scroll.  If
	       the third parameter mouse is given, the action is ignored  when
	       mouse reporting is enabled.

       scroll-forw(count [,units [,mouse] ])
	       This  action  scrolls  is similar to scroll-back	except that it
	       scrolls the other direction.

       secure()
	       This action toggles the Secure Keyboard mode described  in  the
	       section named SECURITY, and is invoked from the securekbd entry
	       in mainMenu.

       select-cursor-end(destname [, ...])
	       This action is similar to select-end except that	it  should  be
	       used with select-cursor-start.

       select-cursor-start()
	       This  action  is	 similar to select-start except	that it	begins
	       the selection at	the current text cursor	position.

       select-end(destname [, ...])
	       This action puts	the currently selected text into  all  of  the
	       selections or cutbuffers	specified by destname.

       select-extend()
	       This  action  tracks the	pointer	and extends the	selection.  It
	       should only be bound to Motion events.

       select-set()
	       This action stores text that corresponds	to the current	selec-
	       tion, without affecting the selection mode.

       select-start()
	       This  action begins text	selection at the current pointer loca-
	       tion.  See the section on POINTER USAGE for information on mak-
	       ing selections.

       send-signal(signame)
	       This action sends the signal named by signame to	the xterm sub-
	       process (the shell or program specified	with  the  -e  command
	       line  option)  and  is  also  invoked by	the suspend, continue,
	       interrupt, hangup, terminate, and  kill	entries	 in  mainMenu.
	       Allowable  signal names are (case is not	significant): tstp (if
	       supported by the	operating system),  suspend  (same  as	tstp),
	       cont  (if  supported  by	the operating system), int, hup, term,
	       quit, alrm, alarm (same as alrm)	and kill.

       set-allow132(on/off/toggle)
	       This action toggles the c132 resource and is also invoked  from
	       the allow132 entry in vtMenu.

       set-altscreen(on/off/toggle)
	       This  action toggles between the	alternate and current screens.

       set-appcursor(on/off/toggle)
	       This action toggles the handling	Application  Cursor  Key  mode
	       and is also invoked by the appcursor entry in vtMenu.

       set-appkeypad(on/off/toggle)
	       This action toggles the handling	of Application Keypad mode and
	       is also invoked by the appkeypad	entry in vtMenu.

       set-autolinefeed(on/off/toggle)
	       This action toggles automatic insertion	of  linefeeds  and  is
	       also invoked by the autolinefeed	entry in vtMenu.

       set-autowrap(on/off/toggle)
	       This  action  toggles  automatic	 wrapping of long lines	and is
	       also invoked by the autowrap entry in vtMenu.

       set-backarrow(on/off/toggle)
	       This action toggles  the	 backarrowKey  resource	 and  is  also
	       invoked from the	backarrow key entry in vtMenu.

       set-cursorblink(on/off/toggle)
	       This  action  toggles  the  cursorBlink	resource  and  is also
	       invoked from the	cursorblink entry in vtMenu.

       set-cursesemul(on/off/toggle)
	       This action toggles the curses resource	and  is	 also  invoked
	       from the	cursesemul entry in vtMenu.

       set-font-doublesize(on/off/toggle)
	       This  action  toggles  the  fontDoublesize resource and is also
	       invoked by the font-doublesize entry in fontMenu.

       set-hp-function-keys(on/off/toggle)
	       This action toggles the hpFunctionKeys  resource	 and  is  also

       string(string)
	       This action inserts the specified text string as	if it had been
	       typed.	Quotation  is  necessary if the	string contains	white-
	       space or	non-alphanumeric characters.  If the  string  argument

	       character constant.

       tek-copy()
	       This action copies the escape codes used	to generate  the  cur-
	       rent  window contents to	a file in the current directory	begin-
	       ning with the name COPY.	 It is also invoked from  the  tekcopy
	       entry in	tekMenu.

       tek-page()
	       This  action clears the Tektronix window	and is also invoked by
	       the tekpage entry in tekMenu.

       tek-reset()
	       This action resets the Tektronix	window and is also invoked  by
	       the tekreset entry in tekMenu.

       vi-button()
	       Handles	a button event (other than press and release) by echo-
	       ing a control sequence computed from the	event's	line number in
	       the screen relative to the current line:

		       ESC ^P
	       or
		       ESC ^N

	       according  to whether the event is before, or after the current
	       line, respectively.  The	^N (or ^P) is repeated once  for  each
	       line that the event differs from	the current line.  The control
	       sequence	is omitted altogether if the button event  is  on  the
	       current line.

       visual-bell()
	       This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
	       This action sends the indicated graphics	input code.

CONTROL	SEQUENCES AND KEYBOARD
       The Xterm Control Sequences document lists the control sequences	 which
       an  application	can  send xterm	to make	it perform various operations.
       Most of these operations	are standardized, from either the DEC or  Tek-
       tronix  terminals, or from more widely used standards such as ISO 6429.

ENVIRONMENT
       Xterm sets the environment variables ``TERM'' for the window  you  have
       created.	 It also uses and sets the environment variable	``DISPLAY'' to
       specify which bit map display terminal to use.  The  environment	 vari-
       able ``WINDOWID'' is set	to the X window	id number of the xterm window.

       Depending on your system	configuration, xterm may also set the  follow-
       ing:

       COLUMNS
	    the	width of the xterm in characters (cf: "stty columns").

       HOME when xterm is configured to	update utmp.

       LINES
	    the	height of the xterm in characters (cf: "stty rows").

       LOGNAME
	    when xterm is configured to	update utmp.

       SHELL
	    when xterm is configured to	update utmp.

       TERMCAP
	    the	 contents  of  the  termcap entry corresponding	to $TERM, with
	    lines and columns values substituted for the  actual  size	window
	    you	have created.

       TERMINFO
	    may	 be defined to a nonstandard location in the configure script.

FILES
       The actual pathnames given may differ on	your system.

       /etc/utmp
	    the	system logfile,	which records user logins.

       /etc/wtmp
	    the	system logfile,	which records user logins and logouts.

       /usr/X11R6/lib/X11/app-defaults/XTerm
	    the	xterm default application resources.

       /usr/X11R6/lib/X11/app-defaults/XTerm-color
	    the	xterm color application	resources.  If your  display  supports
	    color, use this
		      *customization: -color
	    in	your  .Xdefaults  file to automatically	turn on	color in xterm
	    and	similar	applications.

ERROR MESSAGES
       Most of the fatal error messages	from xterm use the following format:
	      xterm: Error XXX,	errno YYY: ZZZ
       The XXX codes (which are	used by	xterm as  its  exit-code)  are	listed
       below, with a brief explanation.

BUGS
       Large pastes do not work	on some	systems.  This is not a	bug in	xterm;
       it  is  a  bug  in  the pseudo terminal driver of those systems.	 xterm
       feeds large pastes to the pty only as fast as the pty will accept data,
       but  some  pty  drivers do not return enough information	to know	if the
       write has succeeded.

       Many of the options are not resettable after xterm starts.

       This program still needs	to be rewritten.  It should be split into very
       modular	sections, with the various emulators being completely separate
       widgets that do not know	about each other.  Ideally, you'd like	to  be
       able  to	 pick and choose emulator widgets and stick them into a	single
       control widget.

       There needs to be a dialog box to allow entry  of  the  Tek  COPY  file
       name.
