[Elecraft] Com ports behavior

[GIWagner@k5kg.com]

I have lost radio control on my K3. To find out why, I tried to connect to the K3 Utility.  Com5 connects just fine at 38400 bits/sec.  When I try to check for firmware, I get a "com5 is closed" message.

Have spent a few hours investigating this, but no joy.  I can connect just fine to a different computer.  Both computers are Win10.

Why would a com port that connects just fine then show as closed?
