[Elecraft] [KX3] Key KX3 from DXLabs using Elecraft USB cable

[John L. W9LHG]

I'm trying to send CW from DXLabs to the KX3 with 
WinWarbler. At the same time, I'm also running 
Commander and DXKeeper.

Commander controls the KX3 fine, and WW outputs CW 
but the KX3 doesn't recognize it. I had hoped that 
the same Com port 5 could be used for both.

Anyone make that work, or are two Com ports required?
