PDP-11 Emulator Question

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.
