[Elecraft] NaP3 and KX3 connection

[Ron Gruner]

I am trying to install NaP3 for my KX3.  In the NaP3's set-up screen, I am 
only getting the option of "COM 6" for the I/O Port.  This is not 
connecting to my KX3 as I believe I need COM 3 based on what I'm seeing in 
my computer's Device Manager.  

How do I enable more port options in the set-up menu so I can select COM 3? 
 I've research this in various archives and Google and haven't seen anyone 
mention this issue before. I've re-booted my computer several times, have 
the right cable from Elecraft, etc. Also, I have set NaP3 to operate in XP 
compatability mode, a suggestion I found on one of the help pages I found.  
Any suggestions?
