[sebhc] H8/H17 emulator available to prelim. trials

[Walter Moore]

The "SPACE" feature used underruns and framing errors to determine what the
next baud rate to try was.  I don't know how you would emulate this.  Bit 6
of I/O port 362Q (from the XCON card) allowed the baud rate to be set to
9600 by default.  Emulating the XCON card might be easier if you haven't.
