To put it simply:

My function is to control the plane's driving and to tell JSBSim with TCP.

JSBSim The current plane posture, then tells me the attitude of the plane via UDP.

As for, why not use TCP one-time fix, because ... I just wanted to try tcp|. Can UDP ...

About the JSBSim end how to achieve, this look at its source code of their own research can be!

Finally, please reprint of friends, the [original] word removed, or, I see will laugh dead
