[Elecraft] (K3) Utility Interface Problem

[Tom Laszynski]

I need help!  I cannot get my computer to communicate with my K3. A 
week ago, I had no trouble doing this.  Now, when I attempted to use 
the transceiver using either the K3 Utility, revision 1.13,5.9, or 
TRX-Manager (a CAT program), there is no handshaking. At one time, 
both of these programs worked separately with the K3.

My computer is a Dell Vostro 320 using Windows 7, Professional, 
SP1.  The interconnect is a straight thru RS-232 cable, DB-9.

Using the utility, under firmware, I continually see "attempting to 
contract K3 on Port COM1 at **** bit/s".

Suspecting the cable, I replaced it with another cable and the 
interface problem continued.  Based upon this test, I assume that the 
original cable was good and now have it back in-line.

Using the "good" cable I tried a second XP based computer with 
1.13.5.9. The problem continued!

To double check, I've ran Dell's diagnostics on the computers (OS Win 
XP, SP3 and Win 7 Pro, SP1). Both machines pass the serial port tests!

I ensured the both the K3 and computers were setup with the same COM 
port, 8N1 and Speeds.  In this case, 38,400 bit/s.

Based upon the above, I suspect that the problem is in my K3.  Most 
likely, I have unknowingly changed the configuration parameter 
affecting communications.

Can someone point me in right direction to solve my interface 
problem? I'm stumped!
