How to load multi MAV

[tangjuju]

Hi, I try to load two MAV using:
./sitl_multiple_run.sh 2^C
./jmavsim_run.sh -p 4560 -l
./jmavsim_run.sh -p 4561 -l
how can I use the system() to control different MAV using the port

No idea what you're trying to do. Can you give a bit more context? Versions? What instructions are you following? What is the goal? What doesn't work? What did you try, etc.
