Here are the pin-outs for the serial (db-9) connector and how they should
be connected for use with a modem.  I can't find the pin-out for parallel
(its' here some place!). If you don't get it send me mail and I'll find 
the info.
 
	db-9	name	db-25
	1	cd	8
	2	td	3
	3	rd	2
	4	dtr	20
	5	sg	7
	6	dsr	6
	7	rts	4
	8	cts	5
	9	ri	22

Yes, 2 and 3 do get reverced for a non-nul modem cable.  I hope I got
all the numbers right (they do match what I have).
