We're using the DINAH interface for
Direwolf in an APRS appliance for the Appalachian Trail Golden
Packet event in an attempt to reduce our reliance on Kenwood APRS
radios (specifically the D710).? In this use, we cut a jumper in
the DINAH to disconnect the volume down behavior.
I was told that the DINAH is designed for
use with AllStar repeater software, so apparently that software
handles things better/differently than Direwolf.

So I'm hitting the standard problem in Windows that Pin6 of the
DIN is connected to the VOLDN pin on the CM119B in DINAH. This
results in the volume being turned down every time the squelch
opens on the radio.??
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?
