Hi Sven,
I used a virtual COM port pair (com0com) on port 1 and 2 and Arduino on 3.
DAVID set to port 3:
If I unplug Arduino, it is like you said, DAVID falls back to port2 but freezes.
I removed the virtual pair and restarted DAVID.
DAVID shows port3 for a second and falls back to "none" now. >>> NOW no freeze.
I reinstalled the virtual pair COM1 and COM2 and tied a application to COM1.
With removed Arduino (COM3) and the App running:
DAVID shows port3 for a second and falls back to COM2 now. >>> NOW no freeze.
Same with no App running at COM1:
DAVID shows port3 for a second and falls back to COM2 now. >>> NOW, freeze again.
So the problem happens falling back to a not used COM port pair.
Maybe that´s simply a com0com issue, but maybe you can do something against using a not used virtual com port pair?
Don't worry that much about this...
