The GraphOn X terminal supports a serial interface.  You open a socket
to a "mini-server" running on a UNIX host.  This mini-server converts
the X protocol to a smaller protocol based on SLIP and sends it to the
terminal via a serial wire or high speed modem.  Performance may be
adequate, depending on your expectations.  Images, pixmaps, and mouse
following are not especially fast.
