[GreenKeys] Jack Hart and i-Telex...

Bingo!

I'd be interested in trying out your software, but none of my PCs have a
plug-in COM card.. just the typical multi-io chip which handles serial,
parallel, maybe the floppy controller, etc.

Do you know which of the older UARTS support the slow speeds? Will the
16550C do it, or 8250, or?

Very cool, thanks in advance.
