  51 second param 0 = solid on, 1 = off, 2-7 blink patterns
  52 2: continuous ~1 blink/sec
  53 3: continuous fast blink
  54 4: continuous medium blink (2/sec ?) 
  55 5: burst of 3? fast blinks
  56 6: continuous slow blinks
  57 7: if led was off 1 very fast blink. depends on previous state
  58 8: no obvious effect, but returns 0 for AF
