"G" – GPIO Settings
<G>[<SUBCMD>[<PARAMS>]]
The G command and sub-commands are used to control the GPIO port. These may be used to set/retrieve
GPIO pin settings or to set the reader up for triggered reading.
Using the GT command, the reader may be configured to read tags in any of the supported inventory
modes for either a fixed time after an edge transition or while a pin is held in a particular state.
