  /**
   *   the protocol so far.
   *
   *   it is packet based. packets should not be longer than 1024 bytes due to hardware
   *   restrictions. We assume udp should be error free enough being the only device on the
   *   cable.
   
   *   MOVE_TO  move mirrors to position x,y
   *   LINE_TO  move mirrors to position x,y and laser on
   *   these commands are 5 bytes long  (uint8 opcode, uint16 x, uint16 y)
   
   *   H_MOVE_TO move mirror horizontaly to position x
   *   use imagination for V_MOVE_TO, H_LINE_TO, V_LINE_TO
   *   these commands are 3 bytes long (uint8 opcode, uint16 l)
   
   *   LASER_POWER sets the laser intensity (uint8 opcode, uint16 power)
   *   we can extend if we need color.
   
   *   (not implemented) FAST_MODE (uint8) Sets the laser in fast mode.
   in fast mode, the motion commands will be set, and the galvo goes to the new position
   as fast as possible.
   // i guess we should have a precise timing parameters.
   
   ----- slow speed ------
   *   (not implemented) SLOW_MODE (uint8 opcode) (default) Sets the laser in slow mode.
   in slow mode means that we go step for step over each pixel with a line raster algorithm.
   
   
   *   STEP_SIZE (uint8 opcode, uint16 size) sets the galvo step size when drawing lines.
   using cheap optics and a short throw the laser spot size is probably a few orders of
   maginitude larger than the theoretical step size of the galvo. This parameter allows
   you to control the step size when going slow.
   
   *   STEP_DELAY (uint8 opcode, uint16 delay) sets an optional delay when drawing each pixels.
   this is sometimes neccesairy for extra illumination of the surface.
