Serial port automatically opened by Cura!! Could cause $$$ damage! #6897

When Cura is opened, and just after the opening credits, it is opening a serial port and sends gcode. It is also toggling DTR on that port. I see no way to disable this behavior. There is no configuration for this. Now in my case, I have many serial ports on my system and some are connected to amateur radio transmitters. When Cura starts up, it sends a bunch of gcode and toggles DTR on the serial port. The result is that the transmitter goes into transmit. In stays in transmit until cura is closed. I just happen to always set my power out to 0W, but the antenna is not connected. If the power is at full, it is into a dead short and my $4000 radio will need repair. Are you going to foot the bill? I see that there are numerous serial port issues here. One should not indiscriminately poll serial ports looking for an open connection. The consequences are beyond a 3D printer bug. You should fix the serial port problem.
