[Elecraft] New KRC2 download utility issues

[Ken Beals]

I have two KRC2s, and had similar problem with both.  Could not get 
either to report fw rev, and when trying to download I would get a "no 
response" error.  The fw that was in both of them was 1.1D5 . 

I used HyperTerm to download, and everything worked fine.  On one of the 
units I had to put it into download mode manually with the commands.  
The other one went right into download mode when I flipped the switch 
and power cycled.

Now that I have upgraded them, I can get the download utility  to get a 
response to the Get F/W Rev. button, but I still get "KRC2 Failed to 
reply: " error when trying to download.  When I initially press the 
Download button, I see the commands sent on the screen, and the KRC2 
starts flashing the LED.  So it seems like it's ready.  Maybe there is a 
timeout loop too short?  The message comes up pretty quickly.

These are both connected to a Win98 machine with real serial ports.
