Re: [Hamlib-developer] Rig Control Error

[Dave B. <g8k...@go...>]

Just a thought.

Does COM3 actually exist, and is it actually the rig?

(Windows can re-enumerate ports as things are connected/removed, or when 
coming out of a sleep state, so sometimes what was on "COMx" is now on 
"COMy" !   There are ways to nail things down to stop that, but you then 
have to be very careful to reconnect things to the same physical USB 
port on the PC.   Put a Hub in the mix, and it gets very complicated 
very fast!)

Is the rig connected by native USB, or via a common USB-Serial / CI-V 
adapter?   Many of such will have their drivers blocked by Windows, as 
there are hoards of fake chipsets out there used for such things, even 
FTDI look-alikes!

If a native USB connection, what does Windows Device Manager say about it?

Does any other software (Icom specific for the rig for example?) work OK 
with the radio?   If not, are the correct drivers installed?

Also, does the rig have CI-V "Trancieve" enabled?   If so, try with that 
disabled.  (Though I think later Hamlib instances would disable that 
automagically if it was detected.)

Just idle thoughts, based on experiences with that OS and COM ports in 
the past work life, where we often had multiple USB and serial connected 
instrumentation "things" at the same time.  Sometimes, Windows going to 
sleep, and then coming out of that, the Universe would implode, as 
various pieces of software suddenly lost sight of what they expected.

That was true from Windows XP through Windows 10.   Glad I have nothing 
to do with that OS any more!.

73.
