/* * 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. * * * * Authors: Fred N. van Kempen, * Based on raw code by RichardG, * * Copyright 2017-2019 Fred N. van Kempen. */ #include #include #include #include #include #include #define HAVE_STDARG_H #include <86box/86box.h>
