Thanks for your reply,
All I want to do is just send the commands to a FlightGear instance
over network with UDP, at the same time listening the properties of
the aircraft over network by using the same protocol. In other words,
I want to implement an external control mechanism.
I tested to see whether this is likely to work or not, I started a
master which would send current properties with generic socket output,
and I started a slave which would get the properties. But this is
wrong I think, because I must send controls to the slave, not the
properties. Anyway, I started the instances with the following
commands:
(master) fgfs --generic=socket,out,1000,127.0.0.1,7755,udp,udptest
(slave) fgfs --generic=socket,in,1000,127.0.0.1,7755,udp,udptest
My intention is not actually do it the master-slave way, but with an
external monitor-and-control system.
Thanks for your attention and sorry for poor info.

How can I control a FG instance with over network using generic interface
with socket input option? (I failed doing this one. maybe my input
format in the xml configuration is invalid. but it's ok for the output
stuff.)
What options your using to start FlightGear with generic i/o?
Check your .xml file carefully. It should contain tags input/input
and output/output with the similar chunks. Master writes to the socket
chunks from output/output and the Slave reads from input/input. If
input chunks does not correspond to output chunks, your can get strange
results.
If your have wrote a C++ code to handle incoming messages, now try to
change your C++ code to drive FG using position and orientation only.
I am using generic protocol to drive FlightGear from external program.
Protocol was changed to use binary i/o, not only binary output as it is done
in current CVS code.
With respect,
Alex
