The xplane_io (X-Plane I/O) program is used to establish network communications, via UDP, with the X-Plane flight simulator running on a computer. The code consists of class libraries that abstract the lower-level UDP packet encoding and decoding details, according to the UDP protocol specifications in X-Plane version 9. Any X-Plane DATA packets can be sent and received, and any X-Plane DataRefs can be set by sending DREF packets to X-Plane.
