NAME
      ct - spawn login to a remote terminal
 


SYNOPSIS
      ct [ options ]  telno ...
 


DESCRIPTION
      The ct utility dials the telephone number of a modem that is
      attached  to  a  terminal and spawns a login process to that
      terminal. The 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  speci-
      fied, 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.
 
      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  monitoring  the
      port, the port monitor reissues the login: prompt.
 
      The user should log out properly before disconnecting.
 


OPTIONS
      The following options are supported:
 
      -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 pro-
            cess 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,  and  for how many minutes,  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  specify-
            ing 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.

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)).
