It's not incrementing at all on the receiving side? Try1 should be going up about once a second.
Add:
DEFINE CHAR_PACING 16667
to the transmit program's defines at the beginning. Maybe the receiver is missing characters 'cause they're coming too fast with the software based serin command. If that fixes it, it'll probably work with a value much less than 16667, but it's a start.
