I've been doing that actually, but like you said it is limited. Now that I'm going to be trying to figure out if its reciving ranges correctly and setting up A/D inputs a bit of a clearer view of whats going on could really help. I'll definitely check out your tutorial and see if I can get it running that way when I get home. I actualy have some various size male serial ports with pinch pins and some awg 22 that I could wire them to a bread board with, so if the software side of it isnt too tough hopefully I'll have it working soon.
