Description : Simple test for RMS. The correct output sequence is:
              Task 1: Waiting for start flag.
              Task 1: Return value is 2.
              Task 2: State 1 -> State 2.
              Task 1: Waiting for start flag.
              Task 1: Return value is 2.
              Task 2: State 2 -> State 1.
              Task 2: State 1 -> State 2.
              Task 1: Waiting for start flag.
              Task 1: Start flag received.
              Task 1: Return value is 1.
              Task 2: State 2 -> State 1.
              Task 2: State 1 -> State 2.
              Task 1: State 1 -> State 2.
              Task 1: State 2 -> State 1.
              Task 1: Return value is 0.
              Task 2: State 2 -> State 1.
              Task 2: State 1 -> State 2.
              Task 1: State 1 -> State 2.
