There is no "standard" per se regards connecting custom hardware to FlightGear. Off-the-shelf stuff like joysticks, throttle quadrants, ruddes, etc will work with the plib library.
The 747 project uses the protocols defined in src/Network to communicate with FlightGear. All the hardware interfacing is done on the simulator side with circuits and electronics specific to the controls and functions of the 747. The circuit design is generic and can be adapted to any model by writing a new application (module) that communicates with the drivers and translates the hardware vectors and switch states into whatever the designer requires. The drivers for the hardware provide an interrupt-based connection via a parallel port for time critical tasks and USB ports for all other static and polled switches and events. Connections to FlightGear for receiving data and sending controls is done with the protocols as noted above and these have also been modified to handle unique aspects of the 747 models and subsystems.
