COM1 and COM3 are irq 4.  COM 2 and COM4 are irq 3.  Although each com port
_can_ be configured for a different irq.  For example, on my computer:
	COM 1 - /dev/ttyS0 - serial mouse (irq 4)
	COM 3 - /dev/ttyS2 - ti-graph link (irq 4)
	COM 2 - /dev/cua1  - 33.6 int. modem (irq 3)

Now you ask, why two irq 4s? Beats me, but BIOS lets me :) And the great
thing about it is that my mouse and the graph link both work at the same
time, odd eh? Well I like it.. Just though I'd share that bit of info with
all of you :)

Later,
Chuck
