I assume "LRC" is some kind of checksum. A checksum is meant to protect devices against damaged commands, so what they do is calculate the correct checksum, compare with the received checksum. If identical, execute command; if different, ignore command (and maybe send something indicating that). So as long as your checksums are not correct, nothing much is going to work.

Huh? Can you point to or show the document that describes "the protocol".

I can only hope it is more detailed and more accurate than what you have provided so far.

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.
