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 thru 03h are disparaged and will be removed from the next version of this specification; they are included for compatibility with version 3.3, though they were probably never used in any implementation 05h get hotkeys Return: AL = status 00h not implemented FFh supported DX:BX -> hotkey list (see below) 06h-0Fh reserved for future enhancements Return: AL = 00h (not implemented) other application-dependent 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 3.5 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. 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 users of this proposal should adhere to the IBM interrupt sharing protocol (see below), which will permit removal of TSRs in arbitrary order and interrupt handler reordering. All TSRs following this proposal should be removable, though they need not keep the code for removing themselves resident; it is acceptable for a separate program to perform the removal. A sample implementation including example TSRs and utility programs may be found in a separate package distributed as AMISLnnn.ZIP (AMISL090.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.

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. 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. Similarly for bits 3 and 9/11, as well as 7 and 0/1. 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 Bitmask of shift states: bit 0: right shift pressed bit 1: left shift pressed bit 2: either control key pressed bit 3: either Alt key pressed bit 4: ScrollLock active bit 5: NumLock active bit 6: CapsLock active bit 7: either shift key pressed bit 8: left control key pressed bit 9: left Alt key pressed bit 10: right control key pressed bit 11: right Alt key pressed bit 12: ScrollLock pressed bit 13: NumLock pressed bit 14: CapsLock pressed bit 15: SysRq key pressed Format of interrupt sharing protocol interrupt handler entry point: Offset Size Description 00h 2 BYTEs short jump to actual start of interrupt handler, immediately following this data block (EBh 10h) 02h DWORD address of next handler in chain 06h WORD signature 424Bh 08h BYTE EOI flag 00h software interrupt or secondary hardware interrupt handler 80h primary hardware interrupt handler (will issue EOI) 09h 2 BYTEs short jump to hardware reset routine must point at a valid FAR procedure (may be just RETF) 0Bh 7 BYTEs reserved (0) Signatures known to be in use: 'Crynwr ' 'SPELLER ' TSR spelling-checker 'heathh ' 'Monitor ' 'Ralf B ' 'FASTMOUS' example TSR included with sample AMIS library code 'Ralf B ' 'NOLPT n ' example TSR -- turn LPTn into bit-bucket 'Ralf B ' 'NOTE ' example TSR -- popup note-taker 'Ralf B ' 'RBkeyswp' RBkeyswap v3.0+ -- swap Esc/~ and LCtrl/CapsLock keys 'Ralf B ' 'SWITCHAR' example TSR -- add switchar() support removed from DOS5 'Ralf B ' 'VGABLANK' example TSR -- VGA-only screen blanker 'TifaWARE' 'EATMEM ' George A.
