ct(1C)                 (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 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 attributes, 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


   7/91                                                                 Page 1

         monitoring the port, the port monitor reissues the login: prompt.

         The user should log out properly before disconnecting.

   BUGS
         The ct program will not work with a DATAKIT Multiplex interface.

   CAVEAT
         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)).
