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)).
