*** Question: Why you code:

instead of:

                  } else if (byte1 >= 0) {  // ASCII  G0

I believe this line was written 10 years ago, so I have no idea (or forgot) why we picked this one, my guess is the code might be a little easier to read with "MSB"...you think the >=0 is better or faster/

Yes, I think it's also faster, as loading of "MSB" + AND would be saved.
Not sure if HotSpot will detect the shortcut!

it actually should be "byte1 < 0x80"
