NAME
       ct - spawn login to a remote terminal

SYNOPSIS
       ct [ -wmin ] [ -xlev ] [ -h ] [ -v ] [ -sspeed ] telno ...

   where:
       min    The maximum number of minutes that ct is to wait for a line
       lev    The debugging level, a single digit in the range 0-9
       speed  The baud rate; default = 1200
       telno  A telephone number comprising up to 31 characters: 0 through
              9, - (delay), = (secondary dial tone), *, and #

DESCRIPTION
       Ct dials the telephone number of a modem that is attached to a
       terminal and spawns a login process to that terminal.  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.  If there are no free lines, ct asks whether 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.

   Options
       -w   Override the dialogue asking for the number of minutes to wait.

       -x   Produce (for debugging) a detailed output of the program
            execution on stderr.  -x9 is the most useful value.

       -h   Prevent ct from hanging up the current line (the default, so the
            line can answer the incoming call), and wait for the termination
            of the ct process before returning control to the user's
            terminal.

       -v   Send a running narrative to the standard error output stream.

       -s   Set the data rate.

   Destination Terminal Logout
       After the user on the destination terminal logs out, ct prompts,
       Reconnect?  If the response begins with the letter n, the line will
       be dropped; otherwise, login will be started again and the login:
       prompt will be printed.

       Note that the destination terminal must be attached to a modem that
       can answer the telephone.

FILES
       /etc/uucp/Devices
       /usr/adm/ctlog

SEE ALSO
       cu(1), ttymon(1M), login(1), uucp(1).

NOTES
       For a shared port, one used for both dial-in and dial-out, the ttymon
       program running on the line must have the -b option specified (see
       ttymon(1M)).
