mark30504 , It sounds like the device you are trying to send to requires ascii data, am I right? If so, just send the characters you want to send like so: SEROUT2 PORTC.6, 84,["80,2E0,00"]. If you notice I'm sending the comma's between the characters. Maybe if you could explain exactly what the device requires for the data stream... It is kind of hard to diagnose the and give a proper answer with the amount of data you have given.
