Data inquiry of server
With each event, the client sends to the server a data package containing
the information about the type of event as well as the current data of all op-
erating elements. If the client produces several events one after the other,
and the server cannot process all of them at once (e.g. quick rotation of
handwheel and simultaneous rotation of the override potentiometer), the
server will send one message containing all events.
7.9.1 Events of Server
By sending a package to the client, the server can influence the status of
the LEDs on the client, set the current value of the handwheel, or request
the current values (position of joystick, handwheel and override potentiome-
ter, as well as state of keys). The server can also read the current states of
the values which can be modified by the server.
7.9.2 Data Transmission
Each of the two socket connections between the client and the server con-
stitutes a channel for the data transmission in each direction. The data
structures relevant for the corresponding data direction are described in this
chapter.
