I'll look into this. My intent us to Close the serial port in all exit paths. But Close calls driver-specific routines. Is this a general problem with all USB to Serial adapter users? Are your device drivers up to date? How do you generally close the K3 utility? I'll put a debug breakpoint on Serial port close and verify that it is invoked in the path you use.
