[arm-allstar] Transmit on Boot or Restart

[Doug Crompton]

Travis,

  You CANNOT turn off or disconnect the radio from a FOB on a server that
uses a COS mode of USB which the 888 does. The reason is that the FOB has
an internal pullup on the COS line and if you disconnect or disable the
radio the line will pull up and simulate keying. This would be shown in the
'V' View option of simpleusb-tune-menu. For the 888 cosfrom needs to be set
to USB.

As long as you are not connected anywhere and you are using simplex mode
turning off or disconnecting the radio would not be a problem but generally
it is advisable to never turn off or disconnect the radio in any case when
using Allstar and in a connected state as the state of the cos line would
be unpredictable.
