  15. //  Simple control utility for FastFlip v2.15
  16. //  Compiled with Borland C++ v2.0
  17. //  Should compile with TurboC (any version) and that "other" compiler
  18. //
  19. //  This util uses the multiplex interface to communicate with FastFlip.
  20. //  See "Microsoft Encyclopedia" (or another DOS reference) for a detailed
  21. //  discussion of the multiplex interrupt.
  22. //
  23. //  FastFlip uses an mpx id of hex 92.
