ct(1C)             UNIX System V(Basic Networking Utilities)             ct(1C)


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 of telno is 31
      characters).  If more than one telephone number is specified, ct tries
      each in succession until one answers; this is useful for specifying
      alternate dialing paths.

      ct tries each line listed in the file /etc/uucp/Devices until it finds an
      available line with appropriate attributes, or runs out of entries.  ct
      uses the following options:

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

      -s speed    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 sends a running
                  narrative to the standard error output stream.

      -w n        If there are no free lines ct asks if it should wait for one,
                  and if so, for how many minutes it should wait before it
                  gives up.  ct continues to try to open the dialers at one-
                  minute intervals until the specified limit is exceeded.  This
                  dialogue may be overridden by specifying the -w n option
                  where 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 standard error.  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 is dropped; otherwise, ttymon
      is started again and the login:  prompt is 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.

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)].
