AX = 55FEh DX = function 0000h initialize ES:BX -> ??? function ES:CX -> ??? structure FFFFh shutdown/reset
Return:
AX = result 4D4Bh only the INT 1B handler will be installed.other:
Handlers for INT 08, INT 09, INT 16, INT 1B, and INT 1C are installed
Notes: The pointer in ES:CX seems to point at a structure defining a callback function when new keyboard keys are pressed. If a TSR returns AX=4D4Bh, QBASIC will stop (with IRQ's and interrupts enabled).. These calls are also made by MS-DOS 6.0's DOSSHELL at startup, exit, and before/after shelling out. Since EDIT.COM and HELP.COM merely invoke QBASIC, those two programs will also cause this interface to be invoked. K3PLUS v6.07+ supports this function, but will never invoke the callback function
