Issue about copter 4.1

according to the source codes of copter4.1.It seemed that no code block about “MAV_CMD_COMPONENT_ARM_DISARM”in file “GCS_Mavlink.cpp”.
Parsing MAV_CMD codes should be MAV_RESULT GCS_MAVLINK_Copter::handle_command_long_packet(const mavlink_command_long_t &packet)
or if there are other files exist,which handle with MAV_CMD?


Maybe what you’re looking for is this?

Many thanks rmackay,but I don’t make clear that the functionality of file “GCS_MavLink.cpp” from directory "Arducopter.there must be difference between "GCS_MavLink.cpp"and “GCS_Common.cpp”
