Particularly good question.  Here is what I have learned about serial
debugging:

1) If you have two 25 pin ports on the back of your computer, ensure
that you know which one is the printer port.  Yes, even if you think you
know, open the case and look to be sure.

2) If you are going to buy a num modem cable or adapter ensure that you
know how it should be wired.  Do not buy a cable or adapter that does
not have wiring information unless you verify it with a meter.  In fact,
insist on it even if it is labeled.

So after spending more money than I want to think about and making
beginner level mistakes I have finally gotten serial debugging working.
Now what was it I needed it for??
