* You can see an example of the encode and decode methods with property ID 108 ''gear/launchbar/state'' which although it is a string in FlightGear it will be transmitted as a SHORT_INT based on the known values. When received the property 120 will act as an intermediary an set the decoded value into ''gear/launchbar/state'' as though it had been transmitted as a string. | * You can see an example of the encode and decode methods with property ID 108 ''gear/launchbar/state'' which although it is a string in FlightGear it will be transmitted as a SHORT_INT based on the known values.
