It should be possible to switch autocapitalization on and off. I think this is a due enhancement.

Hi, would you please be able to provide an example of when this causes an issue?

@rockstorm101 some commands expect data to pass though as-is. The dumbest command I can think of that expects data to pass though is setting an LCD message. In the prusa FW the memory read/write commands expect to contain lower-case hex characters. We can adjust the parser, but that would still break all old firmwares unexpectedly.

See #1298 for a fix proposal which implements what is written here #216 (comment)
