How it works
Escape $, #, } and * with } followed by byte XOR 20 hex. Sum the escaped payload modulo 256 and add $/# framing.
Payload m0,1 has checksum fa and packet bytes 24 6D 30 2C 31 23 66 61.
Limits
Binary-escaped payload framing only. Commands, response run lengths, acknowledgements and target state are not validated. The download is a hex listing; no debugger is contacted.
