  19. I believe it does. (Most any multitasker has to use interrupts or
  20. _considerable_ hardware buffering.) I also have a deeply held

  23. "ADVANCED PROGRAMMING FOR OS/2" or something like that by Petzold
  24. (published by Microsoft) has some discussions of how 1.1,2 
  25. work that will probably be applicable to 2.0.
