You're going to have problems with those two lines. DEC 01010101 will try to send out the number '1 million, 10 thousand, one hundred and one'. Use BIN 01010101 instead of DEC, or just make it easy and use '$55' instead. Also, instead of sending 'DEC 3' or 'DEC 5', just send '3' or '5' and change the receive code to match.
Try that change also and see what happens.Receive
Code:SERIN2 PORTC.4,16468,[WAIT(9),net]
