Establish a stable connection between Microsoft Flight Simulator 10 (FSX) and the VATSIM network servers by creating a transmitting/receiving line on both COM radios, reading transponder code from FSX and accessing the SquawkBox FSUIPC offset parameters.
vPilot can be used to connect Microsoft Flight Simulator 10 (FSX) to the VATSIM network. It is a very basic pilot client with a limited feature set. You can transmit/receive on both COM radios. It reads transponder code from FSX; it can also read transponder mode from FSX if the aircraft supports the SquawkBox FSUIPC offsets.
