Int 2F/AX=160Bh

MS Windows 3.1 - IDENTIFY TSRs

AX = 160Bh
ES:DI = 0000h:0000h

Return:
ES:DI -> TSR information structure (see #02638)

Desc: This call allows Windows-aware TSRs to make themselves known to Windows.

Note: The TSR should first chain to the previous INT 2F handler, then allocate a communication structure, place the returned ES:DI pointer in the first field, and return a pointer to the new structure
