NAME

       ct - spawn login to a remote terminal

SYNOPSIS

       ct [options] telno...

DESCRIPTION

       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  char-
       acters  for  telno  is 0 through 9, -, =, *, and #. The maximum length telno is 31 characters). If more than one telephone number is speci-
       fied, 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
       entries.

       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.

OPTIONS

       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 1200.

       -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 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.

NOTES

       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)).
