No need to hack anything to get another serial port. There are two serial
ports on board, one for the modem, the other one is next to the dip switch.
Here's a real good FAQ page
http://fastolfe.net/misc/i-opener-faq.html , and
there are lots of other very informative Hack/FAQ pages on the web for the
I-Opener.
