[Elecraft] KRC2 rs232 to cpu not working

[Gordon LaPoint]

I purchased a used KRC2 band decoder.   Going through the tests in the 
manual, it works with the buttons on the KRC2, but I can not get the 
unit to communicate with my computer.  I downloaded the software from 
Elecraft, using Windows 7 or 10 and real serial ports (not usb-serial).  
What am I doing wrong? or is the unit bad?  I have not hooked  up the 
auxbuss to the K3 yet, wanted to make sure the bandmap and serial port 
work first.
