The GT adapter has a total of 12 general purpose I/O signals (GPIO[0] to GPIO[11]). By default on power
up all GPIO signals are configured as inputs (direction control = 0). Refer to the serial API documentation
for details on configuring and using GPIO signals.
WARNING: Take care when connecting to GPIO signals to prevent damage to the serial card. Outputs
should only be connected to inputs and not other outputs. Voltage limits as shown above should not be
exceeded.
