# A telephone state machine with pygame
# state 1: WAIT, state 2: RING, state 3: PLAY, state 4: OVER, state5: RING2(on/on/off)
# simulate a hook with your hand on the space-key
# 3 testing sound files: ringringring.ogg for ring, offthehook.ogg for "besetzt", test.ogg for speech
# phone rings after random time (here, 15-90 seconds), gives up after 10 seconds
# important: serial crashes, timeout now 5, maybe size=1, timeout=None to test
