NAME
     ct - spawn login to a remote terminal

SYNOPSIS
     ct [options] telno ...

DESCRIPTION
     ct dials the telephone number of a modem that is attached to
     a  terminal  and  spawns  a  login process to that terminal.
     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 attri-
     butes, or runs  out  of  entries.   ct  uses  the  following
     options:

     -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  for  one,  and if so, for how many
                 minutes it should wait 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.

     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  moni-
     toring  the  port,  the  port  monitor  reissues  the login:
     prompt.

     The user should log out properly before disconnecting.

NOTES
     The ct program will not work with a DATAKIT Multiplex inter-
     face.

     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)).
