[Elecraft] No Connectivity to my COM Port

[Fred Jensen]

In addition to Dick's advice, while viewing the ports, make sure "Show 
hidden devices" is enabled.  Windows 10, I guess driven by Microsoft's 
infinite wisdom, will sometimes change a USB port assignment, but not 
totally remove the former assignment.  It then shows up as in use when 
the ports are enumerated.
