Something has changed on data transmission side in macOS serial drivers and my code broke because of it.
The same code works on Windows 7 and Ubuntu 22.04 inside Parallels Desktop on the same computer.
I have also tried multiple JVM and got the same behavior.
So I have modified the transmission code to cope with the new behavior and it works.
Now I have to test those modifications on Windows and Linux to see if the behavior changes still works.
Today I am outside doing house stuff before the first snow, so no testing will happen today. (Temperature is under 0 C in the morning here.)

You have a PM.
