[K3] Changing COM ports crashes latest K3 utility

Stan:
I had a firmware download failure last night using the latest Utility. Started out OK, but totally disappeared about half way thru MCU 4.39. Got the "blank screen of Death" on the K3. The utility had started hunting for the com port it was already using. Eventually got the force-fed firmware install ( shown in Utility Help) to take on the 4th try.

Think you have to shut the computer down as well as the rig before doing the force-feed. The Utility also showed a com port that was not available: perhaps this is what you ran into.

Re: [K3] Changing COM ports crashes latest K3 utility

This really sounds more like things that have been reported here in the
past, eventually pinned on the com port that gets wings because something
else hijacks the com port in mid-transfer, OR the com port has more than one
item assigned to it and something else running on the computer goes for it.
OR a USB port or separate USB hub is underpowered (this is exceedingly
common), and the hub goes bad with more than one item attached if more than
one stream is active. This last was actually true of motherboard USB ports
on one motherboard, and only a separate PCI USB card, with it's drivers, and
completely separate UN-shared paths to USB devices would fix it. The
motherboard ports "sort-of" worked, the issue was intermittent and it drove
us nuts. Cheep crap on the motherboard.

What OS and version are you people running?

73, Guy.

Re: [K3] Changing COM ports crashes latest K3 utility

In reply to this post by Guy, K2AV

I'm running Win7/64.

Dick D. has provided me with a new version of the K3 utility for testing that does NOT fault on my machine when I change the COM port FROM an invalid or unconnected port. This situation can arise after changing the machine configuration or the port that one is using to talk to the K3. The default COM port, which may no longer be valid, is picked up from the registry.

Nothing specific was identified as being causative, but the exception is no longer thrown under those conditions.

Thank to Dick for the help.

Re: [K3] Changing COM ports crashes latest K3 utility

The new version 1.4.9.9 is available on ftp://ftp.elecraft.com/tmp/K3/K3UTIL
for anyone else that would like to try it. It went to our Field Test team
today. If you experience difficulty, please send me details directly.

Thanks, Stan!
