- * This file helps Angband work with DOS computers.
- *
- * Adapted from "main-ibm.c".
- *
- * Author: Robert Ruehlmann (rr9@angband.org).
- * See "http://thangorodrim.angband.org/".
- *
- * Initial framework (and some code) by Ben Harrison (benh@phial.com).
- *
- * This file requires the (free) DJGPP compiler (based on "gcc").
- * See "http://www.delorie.com/djgpp/".
- *
- * This file uses the (free) "Allegro" library (SVGA graphics library).
- * See "http://www.talula.demon.co.uk/allegro/".
- *
- * To compile this file, use "Makefile.dos", which defines "USE_DOS".
- *
- * See also "main-ibm.c" and "main-win.c".
- *
- *
- * The "lib/user/pref.prf" file contains macro definitions and possible
- * alternative color set definitions.
- *
- * The "lib/user/font.prf" contains attr/char mappings for use with the
- * special fonts in the "lib/xtra/font/" directory.
- *
- * The "lib/user/graf.prf" contains attr/char mappings for use with the
- * special bitmaps in the "lib/xtra/graf/" directory.
- *
- *
- * Both "shift" keys are treated as "identical", and all the modifier keys
- * (control, shift, alt) are ignored when used with "normal" keys, unless
- * they modify the underlying "ascii" value of the key. You must use the
- * new "user pref files" to be able to interact with the keypad and such.
- *
- * Note that "Term_xtra_dos_react()" allows runtime color, graphics,
- * screen resolution, and sound modification.
- *
- *
- * The sound code uses *.wav files placed in the "lib/xtra/sound" folder.
- * Every sound-event can have several samples assigned to it and a random
- * one will be played when the event occures. Look at the
- * "lib/xtra/sound/sound.cfg" configuration file for more informations.
- *
- * The background music uses midi-files (and mod files) from the
- * "lib/xtra/music" folder.
- *
- *
- * Comment by Ben Harrison (benh@phial.com):
- *
- * On my Windows NT box, modes "VESA1" and "VESA2B" seem to work, but
- * result in the game running with no visible output. Mode "VESA2L"
- * clears the screen and then fails silently. All other modes fail
- * instantly. To recover from such "invisible" modes, you can try
- * typing escape, plus control-x, plus escape. XXX XXX XXX

- * Process an event (check for a keypress)
- *
- * The keypress processing code is often the most system dependant part
- * of Angband, since sometimes even the choice of compiler is important.
- *
- * For this file, we divide all keypresses into two catagories, first, the
- * "normal" keys, including all keys required to play Angband, and second,
- * the "special" keys, such as keypad keys, function keys, and various keys
- * used in combination with various modifier keys.
- *
- * To simplify this file, we use Angband's "macro processing" ability, in
- * combination with the "lib/user/pref.prf" file, to handle most of the
- * "special" keys, instead of attempting to fully analyze them here. This
- * file only has to determine when a "special" key has been pressed, and
- * translate it into a simple string which signals the use of a "special"
- * key, the set of modifiers used, if any, and the hardware scan code of
- * the actual key which was pressed. To simplify life for the user, we
- * treat both "shift" keys as identical modifiers.
- *
- * The final encoding is "^_MMMxSS\r", where "MMM" encodes the modifiers
- * ("C" for control, "S" for shift, "A" for alt, or any ordered combination),
- * and "SS" encodes the keypress (as the two "digit" hexidecimal encoding of
- * the scan code of the key that was pressed), and the "^_" and "x" and "\r"
- * delimit the encoding for recognition by the macro processing code.
- *
- * Some important facts about scan codes follow. All "normal" keys use
- * scan codes from 1-58. The "function" keys use 59-68 (and 133-134).
- * The "keypad" keys use 69-83. Escape uses 1. Enter uses 28. Control
- * uses 29. Left Shift uses 42. Right Shift uses 54. PrtScrn uses 55.
- * Alt uses 56. Space uses 57. CapsLock uses 58. NumLock uses 69.
- * ScrollLock uses 70. The "keypad" keys which use scan codes 71-83
- * are ordered KP7,KP8,KP9,KP-,KP4,KP5,KP6,KP+,KP1,KP2,KP3,INS,DEL.
- *
- * Using "bioskey(0x10)" instead of "bioskey(0)" apparently provides more
- * information, including better access to the keypad keys in combination
- * with various modifiers, but only works on "PC's after 6/1/86", and there
- * is no way to determine if the function is provided on a machine. I have
- * been told that without it you cannot detect, for example, control-left.
- * The basic scan code + ascii value pairs returned by the keypad follow,
- * with values in parentheses only available to "bioskey(0x10)".

- * / * - + 1 2 3 4

- *
- * See "lib/user/pref-win.prf" for the "standard" macros for various keys.
- *
- * Certain "bizarre" keypad keys (such as "enter") return a "scan code"
- * of "0xE0", and a "usable" ascii value. These keys should be treated
- * like the normal keys, see below. XXX XXX XXX Note that these "special"
- * keys could be prefixed with an optional "ctrl-^" which would allow them
- * to be used in macros without hurting their use in normal situations.
- *
- * This function also appears in "main-ibm.c". XXX XXX XXX
- *
- * Addition for the DOS version: Dump-screen function with the
- * "Ctrl-Print" key saves a bitmap with the screen contents to
- * "lib/user/dump.bmp".

- *
- * Support for DJGPP v2 by "Scott Egashira (egashira@u.washington.edu)"

- * DOS-286 (conio.h) changes by (Roland Jay Roberts (jay@map.com)
- * Use "Makefile.286" (not ready) to compile this file for DOS-286,
- * and be sure to define "USE_IBM", "USE_WAT", and "USE_286". Also,
- * depending on your compiler, you may need to define "USE_CONIO".
- *
- * True color palette support by "Mike Marcelais (michmarc@microsoft.com)",
- * with interface to the "color_table" array by Ben Harrison.
- *
- * Both "shift" keys are treated as "identical", and all the modifier keys
- * (control, shift, alt) are ignored when used with "normal" keys, unless
- * they modify the underlying "ascii" value of the key. You must use the
- * new "user pref files" to be able to interact with the keypad and such.
- *
- * The "lib/user/pref-ibm.prf" file contains macro definitions and possible
- * alternative color set definitions. The "lib/user/font-ibm.prf" contains
- * attr/char mappings for walls and floors and such.
- *
- * Note the "Term_user_ibm()" function hook, which could allow the user
- * to interact with the "main-ibm.c" visual system. Currently this hook
- * is unused, but, for example, it could allow the user to toggle "sound"
- * or "graphics" modes, or to select the number of screen rows, with the

- *
- * On VGA cards, colors go through a double-indirection when looking
- * up the `real' color when in 16 color mode. The color value in the
- * attribute is looked up in the EGA color registers. Then that value
- * is looked up in the VGA color registers. Then the color is displayed.
- * This is done for compatability. However, the EGA registers are
- * initialized by default to 0..5, 14, 7, 38..3F and not 0..F which means
- * that unless these are reset, the VGA setpalette function will not
- * update the correct palette register!
- *
- * DJGPP's GrSetColor() does _not_ set the EGA palette list, only the
- * VGA color list.
- *
- * Note that the "traditional" method, using "int86(0x10)", is very slow
- * when called in protected mode, so we use a faster method using video
- * ports instead.
- *
- * On Watcom machines, we could simply use the special "_remapallpalette()"
- * function, which not only sets both palette lists (see below) but also
- * checks for legality of the monitor mode, but, if we are doing bitmapped
- * graphics, that function forgets to set the EGA registers for some reason.

- * "special" keys, instead of attempting to fully analyze them here. This
- * file only has to determine when a "special" key has been pressed, and
- * translate it into a simple string which signals the use of a "special"
- * key, the set of modifiers used, if any, and the hardware scan code of
- * the actual key which was pressed. To simplify life for the user, we
- * treat both "shift" keys as identical modifiers.
- *
- * The final encoding is "^_MMMxSS\r", where "MMM" encodes the modifiers
- * ("C" for control, "S" for shift, "A" for alt, or any ordered combination),
- * and "SS" encodes the keypress (as the two "digit" hexidecimal encoding of
- * the scan code of the key that was pressed), and the "^_" and "x" and "\r"
- * delimit the encoding for recognition by the macro processing code.
- *
- * Some important facts about scan codes follow. All "normal" keys use
- * scan codes from 1-58. The "function" keys use 59-68 (and 133-134).
- * The "keypad" keys use 69-83. Escape uses 1. Enter uses 28. Control
- * uses 29. Left Shift uses 42. Right Shift uses 54. PrtScrn uses 55.
- * Alt uses 56. Space uses 57. CapsLock uses 58. NumLock uses 69.
- * ScrollLock uses 70. The "keypad" keys which use scan codes 71-83
- * are ordered KP7,KP8,KP9,KP-,KP4,KP5,KP6,KP+,KP1,KP2,KP3,INS,DEL.
- *
- * Using "bioskey(0x10)" instead of "bioskey(0)" apparently provides more
- * information, including better access to the keypad keys in combination
- * with various modifiers, but only works on "PC's after 6/1/86", and there
- * is no way to determine if the function is provided on a machine. I have
- * been told that without it you cannot detect, for example, control-left.
- * The basic scan code + ascii value pairs returned by the keypad follow,
- * with values in parentheses only available to "bioskey(0x10)".
- *

- *
- * See "pref-ibm.prf" for the "standard" macros for various keys.
- *
- * Certain "bizarre" keypad keys (such as "enter") return a "scan code"
- * of "0xE0", and a "usable" ascii value. These keys should be treated
- * like the normal keys, see below. XXX XXX XXX Note that these "special"
- * keys could be prefixed with an optional "ctrl-^" which would allow them
- * to be used in macros without hurting their use in normal situations.
