	Hello Conrad,
	This is a late nate reply after a work party.

	The uarts on gameports are the easiest to support!  At the
moment I think we support emu10k1(soundblaster), cmi80xx and es1371.
The actual url for the patches should be in the archive, I really
don't remeber at the moment.

	No.  That's what I'm working on (and included in the patches).

	(In regards to windows+serial) Cool.  I didn't known.  At the
moment, MIDI and a serial UART just won't work because the code hasn't
been written (it has before but we are know in the third generation).

	Good luck.

	We peer so suspiciously at each other that we cannot see
	that we Canadians are standing on the mountaintop of human
	wealth, freedom and privilege.
