  NAME

    ct - Spawns getty process to a remote terminal

  SYNOPSIS

    ct [-wn] [-xn] [-] [-v] [-sspeed] telno ...

  DESCRIPTION

    The ct command dials the telephone number of a modem that is attached to a
    terminal, and spawns a getty process to that terminal.  The telno argument
    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 thru 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.

    The ct command will try each line listed in the file /usr/lib/uucp/Devices
    until it finds an available line with appropriate attributes or runs out
    of entries.  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.
    The ct command will continue to try to open the dialers at one-minute
    intervals until the specified limit is exceeded.  The dialogue may be
    overridden by specifying the -wn flag, where n is the maximum number of
    minutes that ct is to wait for a line.

    The -xn flag is used for debugging; it produces a detailed output of the
    program execution on stderr.  The debugging level, n, is a single digit;
    -x9 is the most useful value.

    Normally, ct will hang up the current line, so the line can answer the
    incoming call.  The -h flag will prevent this action.  The -h flag will
    also wait for the termination of the specified ct process before returning
    control to the user's terminal.  If the -v flag is used, ct will send a
    running narrative to stderr.

    The data rate may be set with the -s flag, where speed is expressed in
    baud.  The default rate is 1200.

    After the user on the destination terminal logs out, there are two things
    that could occur depending on what type of getty is on the line (getty or
    uugetty).  For the first case, ct prompts, Reconnect?~.  If the response
    begins with the letter n, the line will be dropped; otherwise, getty will
    be started again and the login: prompt will be displayed.  In the second
    case, there is already a getty (uugetty) on the line, so the login:
    message will appear.

    To log out properly, the user must key in <Ctrl-D>.  Of course, the
    destination terminal must be attached to a modem that can answer the

  NOTES

    For a shared port, one used for both dial-in and dial-out, the uugetty
    command running on the line must have the -r flag specified (see uugetty).
