check your code immediately.there must be some problem with the serial communication portion.you can write methat portion in whch you are initiating the serial comm.
if you are confident of your code then in that case you can try to send data on polling basis and not on interrupt basis as you...

Re: Connecting Rx and Tx with ckts having different supplies
NO you cannot use transistors. Connect the Rx and Tx of +5v powered ckt to the buffer(74HC125).It will output the signals at 3.3 v to the ckt powered by 3.3V.
the obvious disadvantage of using an external eeprom is that it will engage some of the pins of your controller.
check if program memory of pic is non volatile.

Re: Regarding MAX232!
eric,
with regards to your question regarding the need to invert signals from max232,i would like to say you need not do so.max 232 is a RS232
interface.In RS232 protocal, positive logic ranges from -3v to -25v and negative logic ranges from +3v to +25 v. to convert...
