>From what I have been reading about the protocol used, it seems it is not at all robust. Someone else said this as well. The ACKs and NAKs are a good start. These are at times being lost it appears. The utility should have a timer that lets it resend a frame if there is not ACK or NAK that gets back to the utility. If that is done, then each frame will also have to have a sequence number so the radio can recognize a duplicate frame it has already ACKed that got lost. Alternately, a load address for the data would do it by just overwriting the same place with the resent data. 73 - Mike WA8BXN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
