  Without having one on hand to check, i think it's in the QMS book, too.

  The Apple LaserWriter II/NTX book only mentions it in the Diablo
Emulation section (cute!) page 117, 3rd paragraph
  "The LaserWriter II interprets the Control-D key combination as an
   end-of-file command."
Receipt of the control-D is what stops the "stuff coming in" light 
 from flashing.
