MacOs - Erron in creating config for Serial Port #258

Closed maurizioandreotti closed 1 year ago

with latest master (0.4.1.dev18-g4406b3d-dirty) if I try to create a config for a serial port I get:

Exception in thread Thread-9 (worker):

Only change was specifically enabling XON/XOFF protocol instead of specifically disabling it.

If that is what is throwing the Invalid argument, then that is a bug in the termios library in use by the Mac. Can you look to see if there are any updates available?

I do not think that the Icom radio serial ports use any other handshaking XON/XOFF protocol, and if this is broken on Mac OS-X, it would require re-writing the D-Rats serial code to have a working XON/XOFF implementation, and that really is a complete re-write of the serial port.

The quick and dirty fallback is to provide an option to fall back to the broken XON/XOFF handler for Mac OS/X.

Serial port issue on Mac solved updating the system with: brew upgrade all
