KIO fried?  COM port died?  Cable toast?

Use TR LOOPBACK.  Either use it to send commands the K2 should
respond to, or short TXD & RXD on the radio end of the RS-232 cable &
verify that stuff echoes back...

Culprit should be easy to isolate that way.

TBDC starts late Saturday evening here.  Prior to sunset, was on roof mucking
with antenna.  At sunset, back inside to finish K160RX option so I can work
Top Band with my K2.  Then take quick nap as am so knackered, only to wake
up at 0400 local Sunday... just in time to watch those big red circles form 
over
the poles & ruin the morning EU opening.

Now off to help friend move flat - house on farm plot a good hike from road 
- so
will probably be knackered for local Sunday night, too...  ;^(
