# GPOUTPUT GPO GP ## Description:
      The DTMF board has 12 channels of GPIO. This command can assert a GPO in either of the two
      states, HIGH Z or GND. It can also get the current state of the GPO's.

      Upon board reset all 12 GPO's default to a HIGH Z state. Once asserted to GND the GPO's will
      remain there until brought back to HIGH Z through command issue or board reset.

      There are two variants of the get command. The first is a get all where only the command itself
      is issued. The second takes the input source number as the argument to find the status of a
      given input source GPO. The set command takes the input source number and the 'ON' or 'OFF'
      argument.

## Notes:
      status == 'CLOSED' == '1', status == 'OPEN' == '0'
                'CLOSED' == GND
                  'OPEN' == HIGH Z
      Default state upon boot is 'OPEN'

      ***Anytime the connector for GPIO on the DTMF board is connected to a path
      *    to ground, even through resistance, current will flow thus triggering
      *    a GPI condition. I am not sure what the minimum current flow needs to
      *    be to trigger a GPI though. Therefore when asserting a GPO to GND it
      *    will appear to be a GPI.***
