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 characters  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 attri-
     butes, 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 monitoring 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 speci-
                fied 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 infor-
                mation is given.

NOTES
