[Elecraft] help - firmware hangup

[Dick Dievendorff]

Neither microHAM nor Elecraft recommend installing firmware through one of
their devices and the microHAM router (the software in your PC that
implements K3 port sharing for the microHAM CW keyer).

You'll need a USB to Serial adapter or "real" RS-232 cable.

>From the help page I pointed you to earlier:

"If you are using a software sharing program such as N8LP's LP-Bridge or
microHAM's Router between your personal computer and your K3's RS-232 port,
change the cabling so that the PC is connected directly to the K3 without an
intervening software "forwarder". These programs send K3 Programmer's
Reference commands, and a K3 in its bootstrap loader isn't able to process
those commands. Some commands may put the K3 bootstrap loader into an
unresponsive state."


It works fine if you don't start from where you are now.

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.

Thanks.
