INT 2D - ALTERNATE MULTIPLEX INTERRUPT SPECIFICATION (AMIS) [v3.6] AH = multiplex number AL = function 00h installation check 01h get private entry point 02h uninstall 03h request popup 04h determine chained interrupts 05h get hotkey list 06h get device-driver information 07h-0Fh reserved for future enhancements Return: AL = 00h (not implemented) other application-dependent other registers vary by function (also see individual entries below) Return: varies by function Notes: programs should not use fixed multiplex numbers; rather, a program should scan all multiplex numbers from 00h to FFh, remembering the first unused multiplex in case the program is not yet installed. For multiplex numbers which are in use, the program should compare the first 16 bytes of the signature string to determine whether it is already installed on that multiplex number. If not previously installed, it should use the first free multiplex number. functions other than 00h are not valid unless a program is installed on the selected multiplex number to be considered fully compliant with version 3.6 of the specification, programs must implement at least functions 00h, 02h (no resident uninstall code required), and 04h (return value 04h). TSRs that provide hotkeys with which the user can activate them must also implement function 05h. TSRs which provide DOS device drivers must also implement function 06h. The absolute minimum fully-compliant implementation has an overhead of 64 bytes (80 bytes with function 05h) plus 22 bytes per hooked interrupt (for the interrupt sharing protocol header and hook list entry). the signature string and description may be used by memory mappers to display the installed programs to be considered fully compliant, users of this specification must adhere to the IBM interrupt sharing protocol (see #02568), which will permit removal of TSRs in arbitrary order and interrupt handler reordering. All TSRs following this specification should be removable unless they are loaded from CONFIG.SYS, though they need not keep the code for removing themselves resident; it is acceptable for a separate program to perform the interrupt unhooking and memory-freeing steps of removal. A sample public-domain implementation including example TSRs and utility programs may be found in a separate package distributed as AMISLnnn.ZIP (AMISL092.ZIP as of this writing). Please let me know if you choose to follow this proposal. The signature and a list of the private API calls you use would be appreciated, as well.

INT 2D - AMIS v3.0+ - DETERMINE CHAINED INTERRUPTS AL = 04h AH = multiplex number for program BL = interrupt number (except 2Dh) Return: AL = status 00h not implemented (makes TSR non-compliant with specification) 01h (obsolete) unable to determine 02h (obsolete) interrupt hooked 03h (obsolete) interrupt hooked, address returned DX:BX -> TSR's interrupt BL handler 04h list of hooked interrupts returned DX:BX -> interrupt hook list (see #02571) FFh interrupt not hooked Notes: BL is ignored if the TSR returns AL=04h; in that case, the caller needs to scan the return list rather than making additional calls to this function. If the return is not 00h or 04h, then the caller must cycle through the remaining interrupt numbers it wishes to check. return values 01h through 03h may not be used by AMIS v3.6-compliant programs; they are included here solely for compatibility with version 3.3, though they were probably never used in any implementation for return values 01h through 03h, since INT 2D is known to be hooked, the resident code need not test for BL=2Dh (to minimize its size), and the return value is therefore undefined in that case. this function is not valid unless a program is installed on the specified multiplex number; use INT 2D/AL=00h to check SeeAlso: INT 2D/AL=00h,INT 2D/AL=01h,INT 2D/AL=02h,INT 2D/AL=03h,INT 2D/AL=05h SeeAlso: INT 2D/AL=06h Format of AMIS interrupt hook list [array]: Offset Size Description (Table 02571) 00h BYTE interrupt number (last entry in array is 2Dh) 01h WORD offset within hook list's segment of the interrupt handler this will point at the initial short jump of the interrupt sharing protocol header (see #02568) SeeAlso: #02572Top

A set bit in the required states word indicates that the corresponding shift state must be active when the hotkey's scan code is received for the hotkey to be recognized; a clear bit means that the corresponding state may be ignored. A set bit in the disallowed shift states word indicates that the corresponding shift state must be inactive. for the disallowed-states word, if one of the "either" bits is set, then both the corresponding left bit and right bit must be set examples: Ctrl-Alt-Del monitoring: 53h 000Ch 0003h 06h Alt-key tap (DESQview): B8h 0000h 0007h 08h Shf-Shf-N (NOTE.COM): 31h 0003h 000Ch 00h Index: hotkeys;AMIS SeeAlso: #00006 Bitfields for type of AMIS hotkey checking: Bit(s) Description (Table 02573) 0 checks before chaining INT 09 1 checks after chaining INT 09 2 checks before chaining INT 15/AH=4Fh 3 checks after chaining INT 15/AH=4Fh 4 checks on INT 16/AH=00h,01h,02h 5 checks on INT 16/AH=10h,11h,12h 6 checks on INT 16/AH=20h,21h,22h 7 reserved (0) SeeAlso: #02572 Bitfields for AMIS shift states: Bit(s) Description (Table 02574) 0 right shift pressed 1 left shift pressed 2 either control key pressed 3 either Alt key pressed 4 ScrollLock active 5 NumLock active 6 CapsLock active 7 either shift key pressed 8 left control key pressed 9 left Alt key pressed 10 right control key pressed 11 right Alt key pressed 12 ScrollLock pressed 13 NumLock pressed 14 CapsLock pressed 15 SysReq key pressed Notes: if bit 2 is set, either control key may be pressed for the hotkey; if bits 8 and 10 are both set, then both control keys must be pressed.
