[GreenKeys] Serial port issues

[David Ross]

Jeff -

  What problems are you having with TTYSIM running under XP?  I use it 
here for machine testing all the time, generally with a Black Box RS-232 
<-> current loop interface.  The machine is an P3-1133 Dell laptop with 
a built-in DB-9 serial port, TTYSIM seems happy running in an XP Pro 
command window even without the zero-FIFO-length twiddle.

  I wrote TTYSIM to run on a GRiD PC with an 8086 running under DOS 3.1, 
yeah I know the TTYSIM display looks a little strange but the old GRiD 
had a plasma screen.

  Maybe it is time to come up with a more modern version of TTYSIM 
that'll play nice with the ST-8000A -  I have one of those coming.
