Squelch toggle command question

[virgo47]

This is perhaps a more general question, but I don't know where to ask it - and as I'm trying to solve MiG-21 Radio squelch on/off binding, I'll ask here.

I have Squech on and off commands available for binding:

{cockpit_device_id = devices.RADIO, down = device_commands.Squelch, value_down = 0, name = _('Squelch Off'), category = _('Radio Communications')},
{cockpit_device_id = devices.RADIO, down = device_commands.Squelch, value_down = 1, name = _('Squelch On'), category = _('Radio Communications')},

There is no obvious on/off toggle for binding. I tried to search for something about this topic, but the results were quite noisy, mostly related to the "toggle switch" on some joysticks and how to deal with them - but that's not related.

Is there a way how to construct a binding for toggle? Is it some different value or something else? Or is it simply not provided by the module coding?

I'm not sure if I understand you correctly. Do you want to switch between the modes with a push button?

Exactly. Many modules offer both separate ON + OFF bindings and additional toggle binding for switches. Does this require a separate "device_command" that is not implemented for MiG-21bis or is there a way to somehow "compose" such a functionality from existing ON + OFF bindings?

I tried value_down -1 (inspired by how L-39 does it), but that didn't work.

I'm sorry. I don't know how to implement this without additional software (AutoHotkey or similar).
