TTLINK (Program)

Connect to a remote host over a TTY line.  Assumes a circuit has already been
established, whether by dedicated wiring, an autodialer, or otherwise.

Commands:

CONNECT (TO TTY) <octal-line-number> <optional-switches>

  Switches:

  /DUPLEX: FULL or HALF.  If FULL, remote host echoes; if HALF, local host.
  /PARITY: NONE, MARK, SPACE, EVEN, or ODD.
  /LOGFILE: Name of file for logging transcript of remote session.
  /ESCAPE:n Octal value of an ASCII control character to be used as
             the escape character.  Examples: 1=CTRL-A, 32=CTRL-Z.
     ESCAPE character arguments are:
       (blank) - Nothing (null command)
          C - Close Connection
          S - Show Status of Connection
          P - PUSH to new Exec
          Q - Quit logging
          R - Resume logging
          ? - Help
          ^Y (or whatever the escape character is) - Send escape character
            itself to the remote host.
          Anything else causes a beep to sound.

    Initial defaults for CONNECT are FULL DUPLEX, escape character = CTRL-Y,
    and PARITY NONE.  No initial default for line or logfile.  Defaults for
    subsequent CONNECT commands become whatever was specified in the most
    recent CONNECT command. 

STATUS	Display current line number, duplex, log file, and escape character.
HELP    Print this message.
EXIT    If you continue, previous defaults are preserved.

Command line arguments are accepted.

CAUTION: Incoming characters can be lost, especially at high speeds.  This is
feature of the DECSYSTEM-20 front end, which will turn a line off for a few
seconds if characters are coming in too fast for it to handle.  There should
be no problem with outbound characters.
