[Elecraft] Serial port woes with KIO3B

[Pete Smith N4ZR]

Yesterday, I installed a KIO3B update kit in my K-3.  Everything appears 
to work OK except for the USB serial port.  At first, this morning, 
everything seemed to be working OK - the K3 was controlling my amp and 
reading out frequency to DXLab Commander.  I started trying to configure 
N1MM to read radio frequency, and things went steadily downhill from 
there.  At this point, I have no frequency readout on either program, 
and cannot send F-key messages from N1MM.  I have tried every available 
COM port under Windows 10, and checked for hidden ports (none).  I have 
restarted the computer several times with no change.

Can anyone suggest something to try, or a test that might reveal what's 
going on?
