DT_Interupts with 18F2525

[Charlie]

The problem might also be in your interrupt handler, or several other places. You should post all the code.

[amgen]

could also check the serial data polarity coming to pic..... may need inverted

Well...it was swapped pins on the x-bee module header. It was my mistake for grabbing one already soldered up and not checking the pin-out.
Thanks for all the suggestions, here is the code
