[Elecraft] help - firmware hangup

[Robert G. Strickland]

Dick...

Thanks for responding. Still no joy after going through all the HELP 
suggestions. The problem seems to be an inability to connect from the 
computer to the K3. Note, this whole arrangement has been working 
perfectly up to this point. No cable changes, etc. What I get when 
trying to establish a connection to the K3 is a steady hunt through 
various baud rates with no success. I have cycled everything many times. 
I am not using a serial-USB adapter. I am connecting via a microHAM CW 
KEYER [which has been working without problems]. I think I'm getting 
desperate! Thanks again.
