I'm in need of another serial port or two, as I'm tired of swapping
the printer and modem in out all day.  My multifunction I/O card has
only two serial ports, and one is a 9 pin mouse port.

I plan to a serial card with socketed uarts, and upgrade one to the 16550,
for use with the modem.

I've heard that there can be some problems running 4 serial ports under
OS/2, and perhaps with MS-DOS or Windows, with shared interrupts or
cascaded interrupts?

Could somebody go through the gotchas?

What will I need to buy to suit my needs?

My present setup is:
	486dx50
	8mb ram
	340mb IDE hard-drive
	 80mb IDE hard-drive
	3.5" HD floppy-drive
	Hercules Monochrome card and monochrome video (serious!)
	parallel printer
	serial printer 	(db 25)
	serial modem 	(db 25)
	serial mouse	(9 pin)
