[arm-allstar] GPIO control of a Tait Radio.

[Randy Neals]

I've used the GPIO control script on a Motorola and had it working.
It used BCD channel select which the Tait can also do.

Re the TM8100 series, they also have a Serial Control mode.
While I'm not aware of any software for the Pi, it is possible via the very
well documented Tait Computer-Controlled Data Interface (CCDI)
Protocol to change channels (100 memories), or to reconfigure the radio
TX/RX frequency and tone. (ie: Frequency agile remote base)
