Here are the patches (without the serial name fix). Let me know if you want me to change that. Oh, FYI, my changes also open up the com1 terminal in raw mode, which makes the emulation much more accurate. You'll also notice that I added infrastructure for com2->4 in the option parsing. I didn't add it to the serial code, as I think a bunch of things need to be untangled before that can work.
