[Elecraft] K3 doesn't see COM Port on PC anymore

Bob,

If the COM port designation changes for you, then it is a computer problem.
I assume you are using a USB to serial adapter, and the COM port 
assignment is at the mercy of the operating system.  Normally if you 
plug the adapter into the same USB port, the same number will be 
assigned, but plugging it into a different USB port will generate a 
different port designation.

If you have opportunity to use a real serial port on the computer, do 
so, it will take that uncertainty away.  Otherwise, you need help from 
someone who is more familiar than I about how the OS assigns COM port 
numbers.  All I know is that my Edgeport 4 port converter usually comes 
up with the same ports on my XP system.

73,
