+; to build and run on Windows:
+;  - For the first time, install Msys2 (https://www.msys2.org/) and the GCC compiler with `run pacman -S mingw-w64-ucrt-x86_64-gcc`
+;  - Then, build with `pio run -e native` to create the program.exe file
+;  - run by calling the executable from the Mysys shell e.g. `C:/msys64/msys2_shell.cmd -defterm -here -no-start -ucrt64 -c /d/dev/proddy/EMS-ESP32/.pio/build/native/program.exe`
+;
+;  The shell is needed to simulate the Winsock serial port.
+;  You can also integrate into Windows Terminal. See https://www.msys2.org/docs/terminals/
