     This function call, along with Int 15h Functions 81h and 82h,
     defines a simple protocol that can be used to arbitrate use of
     devices by multiple processes. A multitasking program manager
     would be expected to capture Int 15h and provide the appropriate
     service. The default BIOS routine for this function simply returns
     with the carry flag clear and AH = 00h.
