Also the receiving, here is only one wire that is going in , the other wires are used for the LCD, obviously, the lcd works. I am putting the scope on the incoming port adn there is a signal in . The signal is sent every 500ms, Maybe that is too slow ?? and the receiving cant see it ..

ken



Which is why:
serin portB.3 , n2400 , 1000 , loop , [ temp.highbyte , temp.lowbyte , tempf.highbyte , tempf.lowbyte ]

It sits in a tight loop for 1000 ms waiting for anything to come across the serial lines. If nothing happens for 1000 ms, it jumps back to 'loop', which almost immediately goes back into the waiting loop. It's not going to miss anything.

Is the try1 counter going up by one about once a second on both ends?
