Hi All,

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.

https://github.com/emuehlstein/baofeng_bfc50

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,

You might ask this question in the [chirp_devel] mailing list to have a more targeted audience.

I use Serial Port Monitor here. I don't know if it will run in Parallels VM, but it runs in my Windows VirtualBox VM. It is a paid program. I bought it when it was only $69. It has a ridiculous price of $199 now! It looks like you can get a "Non-Commercial FREE" copy in exchange for a review. https://www.serial-port-monitor.org/

There is a "free" program that I used before purchasing what I am using now. It provides 5, 20-minute sessions per day. You've got nothing to lose by trying it. https://freeserialanalyzer.com/

I just ordered a BF-C50 from a seller on AliExpress. If they are a legitimate seller, the radio should be delivered around the 2nd week of October. If you haven't gotten yours sorted out by then, I can make some serial captures for you.
