Simply send the full string to the serial port of the radio. I guess it would be a non-KISS way of doing it. We could even stick some kind of ASCII flag on each end of the "frame". From our testing, we knew that the data sent in was displayed on the other end. The drawback here is the need for external hardware to do this. So, for starters, we would have to look at doing this with external computers to run a true "APRS"-like protocol. > > Is there any kind of error detection/correction at all? Or would the eternal application/devices have to provide some sort of checksum/ACK/NAK process? What happens if the path between the two radios is less than "full-smash" hard-quieted? -- Stephen H.
