I'm working to discover the cloning protocol for the Baofeng BF-C50.  I have the OEM programming software installed in a Win11 VM and I can read/write the memory from the radio.  Despite trying several tools, I can't find a solution which allows me to sniff both the RX and TX of a serial connection in Win11 for ARM.

Instead, I've started a couple of Python scripts which emulate one side or the other and I've been slowly teasing data out of the radio and programmer.  As is, my fake programmer sends the 4 byte initialization string the radio expects, the radio replies with 12 bytes, the programmer ACKs that and the radio sends a bunch more bytes but not enough bytes to be the full memory.

Any recommendations for a serial sniffing tool which will work in a Win11 Parallels VM?  Recommendations on how to proceed with the script to discovering the rest of the download routine?

Thanks,

Eric
