[Elecraft] serial cable connected to the K2 by accident

What normally happens is that you blow the auxbus, and end up with a dead 
radio. Since yours still works, you probably got away with it. Perhaps 
there was nothing connected to that pin on your cable.

hi, 

what can happen if a full serial cable from the PC is connected to the K2 
serial IO port?
I have a special cable for the K2 with RX TX GND lines only, but I mixed it 
up with the normal serial cable.

I have the 10W K2. CAT-control works fine - could I have done some damage 
to the K2 which is not noticable now? If yes, how can I test it?
