Cool. I didn't know that. Didn't one of the other hardware-seller
types -- don't remember who -- have a 16550 card built, and then
basically self-destruct over the software issues?

But V-TERM does such an AWESOME job of vt100 emulation -- it even does
double high/double wide correctly. Not to mention the fact that it can
handle anything EMACS throws at it, and nothing stress-tests a
terminal emulator like EMACS. :-)
I do understand your caveat. Please understand that I did specify
BASIC terminal emulators.
I would not use an OS-9 terminal program that did not go through the
proper descriptor/driver interface.

Nice... If I had a job I'd get one.
