Serin2/ Serout2

My final use is with radios, but I am now trying direct wires.

I have experimented with time delays to make sure the receiver is ready, but it appears to lock up when trying to send the return command.

Thanks

Are you sending the data bidirectionally across the same wire? Or are you sending on C.5 and receiving on C.4 on both parts, using two wires?

I am sending and receiving on the two ports on each PIC with two wires.

Not sure why, but the problem was solved when I reset each Port to Input after transmitting or receiving.
