Dwayne,

I use Portb.0 as key and Portd.4 to measure pulse. I am decodeing apulse stream from a radio to determine a time zero " time begins now pulse" the first tone is 1khz for approx. 10 cycles and changes to 2khz ,I detect this change and output a pulse for time begins now. I t was working fine until I added the serin2 command. I need this for a command structure input via the telemetry link. I have lots of time between keys 2 to 6 secs


Thanks again

Scott
