This device may or may not always be connected, and when connected may be connected to any one of several different ports; I'd like my program to handle this gracefully.

The code has been working very well for awhile, but recently a fellow engineer's machine started to fail and didn't work right again until it was restarted. The project uses Qt 4.5.0, but that shouldn't be very relevant to this question. I register for the notificati...

I have read this: http...
