          NAME
               ct - spawn getty to a remote terminal

          SYNOPSIS
               ct [ -wn ] [ -xn ] [ -h ] [ -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.  Telno is a telephone number, with equal signs for
               secondary dial tones and minus signs for delays at appropri-
               ate 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 speci-
               fied, the ct command 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
               /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.
               ct will continue to try to open the dialers at one-minute
               intervals until the specified limit is exceeded.  The dialo-
               gue may be overridden by specifying the -wn option, where n
               is the maximum number of minutes that ct is to wait for a
               line.

               The -xn option 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 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.  If the -v option is used, ct will send a
               running narrative to the standard error output stream.

               The data rate may be set with the -s option, 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
               printed.  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 type control D.

               Of course, the destination terminal must be attached to a
               modem that can answer the telephone.

          BUGS
               For a shared port, one used for both dial-in and dial-out,
               the uugetty program running on the line must have the -r
               option specified [see uugetty(1M)].
