Dave,

I've loaded your TX code into one 12F675 and connected to the Linx TX and it is transmitting data. ( I changed the interval from 15 seconds to 1.5 seconds)

I then loaded your RX code as seen below into another 12F675 and I'm not getting anything out of GPIO.2. I connected a LED to the data out of the receiver and it does flash in sync with the TX data going out.

I connect GPIO.2 of the RX PIC to Hyperterminal set at 8N1, 9600 and get nothing at all and I connected an LED to GPIO.2 and nothing there either.

Shouldn't I be getting something on the RX PIC ?

Code:
