Raw Blame History

/*
* 86Box A hypervisor and IBM PC system emulator that specializes in
* running old operating systems and software designed for IBM
* PC systems and compatibles from 1981 through fairly recent
* system designs based on the PCI bus.
*
* This file is part of the 86Box distribution.
*
* Define the XKBD to ScanCode translation tables for VNC.
*
* VNC uses the XKBD key code definitions to transport keystroke
* information, so we just need some tables to translate those
* into PC-ready scan codes.
*
* We only support XKBD pages 0 (Latin-1) and 255 (special keys)
* in these tables, other pages (languages) not [yet] supported.
*
* The tables define up to two keystrokes.. the upper byte is
* the first keystroke, and the lower byte the second. If value
* is 0x00, the keystroke is not sent.
*
* NOTE: The values are as defined in the Microsoft document named
* "Keyboard Scan Code Specification", version 1.3a of 2000/03/16.
