       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

	     The data rate may be set with the -s option. speed	 is  expressed
	     in	baud rates.  The default baud rate is 1200.

       -v    If	 the -v	(verbose) option is used,  ct will send	a running nar-
	     rative 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 option. 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 detailed	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)).
