[arm-allstar] serial or CLI control of PTT/COS

[Patrick Perdue]

hi:

Is there a way to manually key/unkey the node from either a serial port 
or directly from bash? I'm thinking of building an analog bridge to a 
virtual radio that supports squelch and PTT via serial, and want to 
drive carrier detection and PTT of my locally connected HamVoIP node 
with it instead of carrier detect from simpleusb.
