[Elecraft] Fwd: K3 Failed DSP Firmware Download

>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.
