mark30504, You are trying to send a combination that is bigger than a byte (0-255). Just send it as 2 individual bytes bytes like: SEROUT2 PORTC.6, 84,[$80,$02,$E0,$01]. Or you could if you have the decimal equivelents available send the string: SEROUT2 PORTC.6, 84,[HEX2 first byte variable,HEX4 second word variable,HEX2 third byte variable]
