7.2.16. Function 0201 - Set Real Mode Interrupt Vector

PMODE/W API

This function Sets the real mode segment:offset for the specified interrupt vector.

In:
   AX     = 0201h
   BL     = interrupt number
   CX:DX  = segment:offset of real mode interrupt handler
Out:
   always successful:
     carry flag clear

Notes:
The value passed in CX must be a real mode segment address, not a protected mode selector. Consequently, the interrupt handler must either reside in DOS memory (below the 1M boundary) or the client must allocate a real mode callback address.
