[arm-allstar] Interfacing URIx with Zetron ZR310 controller

 I assume your problem is COS to the FOB.  There is no ppinvert. The Pi has
no parallel port. All audio and control lines are via the USB FOB. -  the
options in simpleusb-tune-menu item J are usb or usbinvert.  If you are
using a DMK/URI it is pin 8. You need to determine the level coming from
the controller when you have a receive signal. If it goes low on signal
then you would use usbinvert. If it goes high you would use usb.  The low
level needs to be 0 volts or close to it and the high can be anything above
2 volts or so.

You can use the V option in simpleusb-tune-menu to realtime view the COS
INPUT line.  It will show keyed or clear depending on the state.  If COS is
not keyed you will have no audio into Allstar (RX audio). If COS is hung
keyed you will have no audio out of Allstar (TX audio) until it clears.
