[arm-allstar] Using PL instead of COS

[LaRoy McCann]

Doug,
There is no other controller.  The exec II is a mobile radio converted 
to a repeater.  It will be controlled directly with allstar.  I curently 
have 2 repeaters running on allstar and will soon have 3 or 4 more 
running on allstar.

Allstar will switch direction (usb or usb invert) but since the radio 
gives +10v when unsquelched, I will need to make a buffer because the 
raspberry pi needs to see the input go to ground.

The TS64 signal is an open collector to ground so it interfaces well 
with allstar.
