ok, so I got a serial adapter finally, and started testing my code. The function for converting the hex commands to binary works beautifully, while the function for converting the binary values returned into decimal worked, but the values were off by an order of magnitude, and in reviewing the algorithm, I realized it was stupid, lol. I'll iron that out at work tomorrow, and then once that's tested and working, I can throw it in my car and see if it can talk.
