[chbot] USB - RS232 modules.

[Chris Hellyar]

Hurro,

Yeah, I did think about some options like that but the PC software bit 
of it is fixed so RTS/DTR is what I've got to work with.

I've done the old keyboard guts a few times for inputs.  :-)

Would be sooo much easier if modern PC's had parallel and serial ports 
like the good old days of course.

Cheers, Me.
