Raw handling: Send a request, read the answer, handle the result
A sequence chain will bring the easiest result.
Step 1 is the initializing step. It checks the connection. The ramp from "not established" to "established" will be used for initialize functions. It switches the receiving on.
Step 2 sends the request.
Step 3 calculates the next request.
Step 4 reads the answer. It it was received the receiving is suspended.
Step 5 handles the received data.
Step 6 switches back to step 1.
