Looks like just the program. I suppose with all the serial details it won't evenbe worth taking apart or otherwise debugging the (VB) program that came with the hardware. Likely better off just writing something completely from scratch in C which will serve the purpose of doing what the original program is lacking, plus what it already does, but a lot faster/smoother and without the occassional crash.

Then I'll email the vendor and let them know about the software - and that they can get stuffed if they think I'll share it with them. They have yet to reply to any emails and that ticks me off.
