Re: Sqelch Open attached to VOLUME DOWN in Schematic

Yes and cut the COS jumper on the DINAH board and it is useful for digital activities.
?
The COS circuit is required only for voice modes, typically?AllStar image, and the software must specifically?manage the handling of this signal.? DINAH was bult?for the AllStar image, and the AllStar. image expected?COS on this pin.

So here is the question:? Why didn't DINAH use one of the available GPIO pins instead of VOLDN?? Is it because the software that is typically used with DINAH doesn't support that?
I'd love to use DINAH on Windows.? I'm perfectly happy to update the client software to support a GPIO in open source projects.? I'm an embedded software developer, and I've recently re-joined the Windows team at Microsoft As well.? So I'd be pleased to help fix this... But I'll need a bit more information on what drove that electrical decision in the schematic. And I'll need to know the key pieces of software that DINAH is targeting.? I'm aware of DireWolf, but what else?
