Thanks for the info.. seems we had a different problem.
Hyperterminal showed no data on that either, so I updated Easy C and the USB to serial driver. This cleared up some of the problems, but now the output (from the accelerometer and gyro) appears to be freezing. Monitoring the output on the hyperterminal showed that there was nothing coming into the COM port. It does work as long as we only try to listen to the accelerometer or only the gyro, but not both. Weird..
We'll keep messing with it.
Thanks again!
