[Elecraft] KX3 Utility problem: serial port is closed

[Don Wilhelm]

Hank,

Installing KX3 Utility will do nothing for changing what your computer 
does about COM Ports vs USB port assignment.  It is now apparent that 
your computer is not properly recognizing the FTDI USB to Serial adapter.

Download and install the FTDI drivers from the FTDI website.
What you are trying to deal with is an FTDI USB to Serial adapter.  Just 
because the KXUSB cable is sold by Elecraft does not change that fact - 
the FTDI chipset is not an Elecraft device, but an FTDI device even 
though it is included in the KXUSB.

73,
Don W3FPR
