  The idea of NONE is to let the console driver handle the escape sequences,
  which, in theory at least, would give not only ANSI emulation, but also any
  other kind of emulation that might be provided by alternative console
  drivers, if any existed.

  For this to work, ckocon.c would need to be modified to make higher-level
  calls, like VioWrtTTY(), DosWrite(), or (simply) write(), rather than
  VioWrt*Cell() and similar, and it would also have to give up its rollback
  feature, and its status line and help screens would also have to be
  forgotten or else done in an ANSI way.

  As matters stand, we already have perfectly good ANSI emulation built in,
  and there are no alternative console drivers available, so there is no point
  in having a terminal type of NONE, so it is commented out.  However, should
  you uncomment it, it will work like a "glass tty" -- no escape sequence
  interpretation at all; somewhat similar to debug mode, except without the
  debugging (no highlighting of control chars or escape sequences); help
  screens, status line, and rollback will still work.

  This check was added in C-Kermit 6.0 or 7.0 but it turns out to be
  unhelpful in the situation where the remote is running a script that sends
  REMOTE commands to the local workstation.  What happens is, the local
  server executes the command and sends the result back as screen text, which
  is indicated by using an X packet instead of an F packet as the file
  header.  There are two parts to this: executing the command under control
  of the remote Kermit, which is desirable (and in fact some big applications
  depend on it, and therefore never installed any new C-Kermit versions after
  5A), and displaying the result.  Commenting out the check allows the
  command to be executed, but the result is still sent back to the remote in
  a file transfer, where it vanishes into the ether.  Actually it's on the
  communication connection, mixed in with the packets.  Pretty amazing that
  the file transfer still works, right?

     remote host { blah blah } | cmd              This end
     remote host { blah blah | cmd }              That end

   Or both:

     remote host blah blah | cmd > file           This end, etc etc...

   Note: this really only makes sense for REMOTE HOST, but why be picky?
   Call after calling cmtxt(), with pointer to string that cmtxt() parsed,
