[Elecraft] [Elecraft-K3] K3s won't connect to PC

[Don Wilhelm]

Checking communications capability with K3 Utility is always a good 
first step when you have problems with communications with the K3/K3S 
(similar for KX3/KX2).
If the Utility can communicate, then you should know to look to your 
computer applications and their setup information for the problem.

If the Utility cannot connect, it is either a computer port assignment 
problem, a USB to serial adapter problem (including the adapter built 
into the K3S) or a K3/K3S problem.

So depending on the results of the K3 Utility "Test Communications", you 
will know where to look for the problem.  Often it is a computer problem 
such as Tony discovered.

And of all the ports I use for both K3's and all the programs and hardware, that was the only one that changed from 16 to 12. Go figure. Went into Device Manager and changed the port number back to what it was. Weird.
