INT 2C R - RM386 v6.00 - CLOAKING - CALL PROTECTED-MODE PASSALONG CHAIN
Note:   when this interrupt is invoked in V86 mode, RM386 will invoke the first
          in a chain of protected-mode handlers, and will only pass execution
          to the V86-mode INT 2C handler if none of the handlers in the
          passalong chain handle the call instead.  This is the method by which
          the real-mode stub of a cloaked application communicates with the
          protected-mode portion.
Program: RM386 (RAM-MAN/386) is the memory manager included in Helix Software's
          Netroom
