You constructed a system with many components (computer, peripheral, cable, software) and that system fails to provide the response you expect. So something is wrong, or even: several things could be wrong.

When debugging a system, there is only one correct attitude: everything is suspect.

The right approach is: start from the facts, not opinions, impressions, gut feelings. And you did not provide many facts, the most important ones are (if I understood you correctly):
- your code receives a command instead of a response (like an echo);
- downloading the firmware was successful;
- the "documentation" is inconsistent.

You care most about one specific command. I don't, I care first about successful communications, I want to see a successful command-response sequence, no matter which command it is. Once you get a reasonable response, you have a new fact, telling you how the NUM, DATA, LRC fields really must be used; the importance of this is stressed by the inconsistency in the "documentation". The simpler the command is, the more likely it is to be accepted; and then you can study the response, as I did for the example version string which does not follow the rules of the "documentation".

I wish you good luck, and hope you will let us know how you made real progress if and when that happens.

The Windows 11 "taskbar" is disgusting. It should be at the left of the screen, with real icons, with text, progress, etc. They downgraded my developer PC to a bloody iPhone.
