"Hi Jaron, thanks for your kindness.
I'm now can sent the command to FG via another machine already and everything works well.
I hope we will share the knowledge about FG and the comm.sys. again later."

"Hi Jaron, I changed the ip you said but I still can not command the FG via UAVPlayground in another machine.
I don't know how to do. Could you please help me?"

"Hi Jaron, I can't command the Flightgear via another machine (data receive is ok).
Sould I have to code something?"
