[arm-allstar] Difference between duplex=1 and duplex=3?

[David Andrzejewski]

Ahh, I think I get it - so COS in = PTT out in any of the duplex modes,
just duplex=3 means nothing receive audio input goes to the TX audio
output ever. 

So in duplex=1, audio to linked nodes is one-way as well?

The setup I'm currently working on is the audio interface is going to a
port on a multi-port repeater controller, which is why 3 seems to be the
option that works best.

I appreciate the help!
