[Elecraft] Diagnosing Serial Port Issue

[Pete Smith N4ZR]

My station took a lightning hit a couple of weeks ago, and I have just 
finished configuring a new computer with my old C drive.  That all works 
fine, but for some reason I'm not able to get COM port communication 
between N1MM Logger and my K3.  I'm using a USB-to-serial cable.  When I 
open the Config menu, I see COM 11 with an asterisk indicating that it 
doesn't exist, and COM1 as another option.This seems odd because my 
setup used COM3 for radio and COM6 for CW keying before the event.

I'm at a loss about how to diagnose the problem.  It could be the IO 
board in the K3, I suppose (shudder) or the RS232 to USB adapter cable. 
I can just buy another cable, to rule that out, but is there a way to 
run a self-test on the K3 IO to see if it is damaged?

As an aside, I have had a KIO3B on order for +/- 2 years, but I don't 
know when or if that's going to happen. The radio seems otherwise to be 
fine; I've tested its sensitivity and power output on several bands. I 
just want to try to dig myself out of this before CQWW and SS.
