Is anyone aware of any serial control commands that exist for the IC-R9500 yet are not in the table at the back of the manual? I'm trying to write some automated control software but one but I can figure out how to do a tone scan over remote.
In looking at the manual, I don't see any way of doing this either. At first, I presumed it was a SCAN-related command but it's not. If you look at the Tone Scan section it's an "advanced" feature of the T.SQL function.
Hmm, is there any way to READ the MENU options? If there was a way to SELECT the FUNC keys then you may have a way to do it...
It doesn't look like ICOM presents any path to manipulate that feature or like you say, it's undocumented.
You might send an inquiry to ICOM and see if there's further information.
PS. I found this but I don't think I'm not sure it'll be helpful -- looks outdated:
