 You can now simply declare multiple variables of type TESTCASE_INSTANCEDATA_T which contains the data per instance. When calling the state machine just point to one of these variables.
-To let the state machine know which object number it currently works with a predefined member of the struct called ''inst_id'' is available. You can set it to any value that makes sense in the state handler (e.g. provide the COM port number the machine currently processes).

 ===== Provide an own Instance Structure =====
-Sometimes it makes sense to provide an own instance structure. In our example we want to store the baud rate, parity and other values relevant for each serial port. So the state machine can store there all local data and makes it "object oriented" this way.
+Sometimes it makes sense to provide an own instance structure. In our example we want to store the baud rate, parity and other values relevant for each serial port.
 So first define an own struct in a file called ''own_inst_type.h'' (as an example). As you can see in the code below local data like the noRxBytes is defined there but also variables that are initialized just once like the bit rate which is more like a parameter.
