[Elecraft] Firmware Loading!

[Dick Dievendorff]

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.
