       ct - spawn login	to a remote terminal

       ct [options] telno...

       The  ct	utility	dials the telephone number of a	modem that is attached
       to a terminal and spawns	a login	process	to that	terminal. The telno is
       a telephone number, with	equal signs for	secondary dial tones and minus
       signs for delays	at appropriate places. (The set	 of  legal  characters
       for  telno  is 0	through	9, -, =, *, and	#. The maximum length telno is
       31 characters). If more than one	telephone number is specified, ct will
       try each	in succession until one	answers; this is useful	for specifying
       alternate dialing paths.

       ct will try each	line listed in the  file  /etc/uucp/Devices  until  it
       finds an	available line with appropriate	attributes, or runs out	of en-

       After the user on the destination terminal  logs	 out,  there  are  two
       things that could occur depending on what type of port monitor is moni-
       toring the port.	In the case of no port monitor,	ct prompts: Reconnect?
       If  the	response  begins  with the letter n, the line will be dropped;
       otherwise, ttymon will be started again and the login: prompt  will  be
       printed.	 In  the  second  case,	where a	port monitor is	monitoring the
       port, the port monitor reissues the login: prompt.

       The user	should log out properly	before disconnecting.

       The following options are supported:

       -h	       Normally,  ct will hang up the current line so that  it
		       can be used to answer the incoming call.	 The -h	option
		       will prevent this action. The -h	option will also  wait
		       for  the	termination of the specified ct	process	before
		       returning control to the	user's terminal.

       -sspeed	       The data	rate may be set	with the -s option.  speed  is
		       expressed  in  baud  rates.   The  default baud rate is

       -v	       If the -v (verbose) option is used,   ct	 will  send  a
		       running narrative to the	standard error output stream.

       -wn	       If  there  are  no  free	lines ct will ask if it	should
		       wait, and for how many minutes,	before it gives	up. ct
		       will  continue to try to	open the dialers at one-minute
		       intervals until the specified limit is  exceeded.  This
		       dialogue	 may  be  overridden by	specifying the -wn op-
		       tion. n is the maximum number of	minutes	that ct	is  to
		       wait for	a line.

       -xn	       This  option  is	 used for debugging; it	produces a de-
		       tailed output of	the program execution on stderr. n  is
		       a  single  number between 0 and 9. As n increases to 9,
		       more detailed debugging information is given.



       See attributes(5) for descriptions of the following attributes:

       The ct program will not work with a DATAKIT Multiplex interface.

       For a shared port, one used for both dial-in and	dial-out,  the	ttymon
       program	running	 on the	line must have the -r and -b options specified
       (see ttymon(1M)).
