Format of AMIS hotkey list

Back ] Next ]

Offset Size Description

00h

BYTE

type of hotkey checking (see #02573)

01h

BYTE

number of hotkeys (may be zero if TSR can disable hotkeys)

02h

6N BYTEs

this will point at the initial short jump of the interrupt sharing protocol header (see #02568)
Offset Size Description

00h

BYTE

hotkey scan code (00h/80h if shift states only)
hotkey triggers on release if bit 7 set

01h

WORD

required shift states (see #02574)

03h

WORD

disallowed shift states (see #02574)

05h

BYTE

hotkey flags (see #02575)

Note:

Except for bit 7, the shift states correspond exactly to the return values from INT 16/AH=12h. 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
Shift-Shift-N (NOTE.COM) : 31h 0003h 000Ch 00h
