mmm, can you do one test with a PC???

What is the result if you send to PC ???

what is the result when you receive fom PC ?

Can you test a 1200 bauds and decrease you crystal speed by 4. I.E. Use a code @ 16MHZ for a 1200 bauds who works and change the crystal to 4MHZ without changing the DEFINE OSC 16... but changing the HS setting to XT.
