* Keyboard mappings for DEC LK201/401/501 keyboards - * - * 17.05.99 Michael Engel (engel@unix-ag.org) - * - * DEC US keyboards generate keycodes in the range 0x55 - 0xfb - * - * This conflicts with Linux scancode conventions which define - * 0x00-0x7f as "normal" and 0x80-0xff as "shifted" scancodes, so we - * have to remap the keycodes to 0x00-0x7f with the scancodeRemap - * array. The generated scancode is simply the number of the key counted - * from the left upper to the right lower corner of the keyboard ... - * - * These scancodes are then being remapped (I hope ;-)) with the - * lk501*map[] arrays which define scancode -> Linux code mapping - * - * Oh man is this horrible ;-) - * - * Scancodes with dual labels exist for keyboards as follows: - * - * code: left label / right label - * - * 0x73: LKx01, LK421 / LK443, LK444 - * 0x74: LKx01, LK421 / LK443, LK444 - * 0x7c: LKx01, LK421 / LK443, LK444 - * 0x8a: LKx01, LK421 / LK443, LK444 - * 0x8b: LKx01, LK421 / LK443, LK444 - * 0x8c: LKx01, LK421 / LK443, LK444 - * 0x8d: LKx01, LK421 / LK443, LK444 - * 0x8e: LKx01, LK421 / LK443, LK444 - * 0x8f: LKx01, LK421 / LK443, LK444 - * 0x9c: LKx01, LK421 / LK443, LK444 - * 0xa1: LKx01, LK421 / LK443, LK444 - * 0xa2: LKx01, LK421 / LK443, LK444 - * 0xa3: LKx01, LK421 / LK443, LK444 - * 0xa4: LKx01, LK421 / LK443, LK444 - * 0xad: LK421 / LK443, LK444 - * 0xc9: LKx01, LK421, LK443 / LK444 - * 0xf7: LKx01, LK443 / LK444 - */ - -unsigned char scancodeRemap[256] = { -/* ----- */ -/* 0 */ 0, 0, 0, 0, -/* ----- */ -/* 4 */ 0, 0, 0, 0, -/* ----- */ -/* 8 */ 0, 0, 0, 0, -/* ----- */ -/* c */ 0, 0, 0, 0, -/* ----- */ -/* 10 */ 0, 0, 0, 0, -/* ----- */ -/* 14 */ 0, 0, 0, 0, -/* ----- */ -/* 18 */ 0, 0, 0, 0, -/* ----- */ -/* 1c */ 0, 0, 0, 0, -/* ----- */ -/* 20 */ 0, 0, 0, 0, -/* ----- */ -/* 24 */ 0, 0, 0, 0, -/* ----- */ -/* 28 */ 0, 0, 0, 0, -/* ----- */ -/* 2c */ 0, 0, 0, 0, -/* ----- */ -/* 30 */ 0, 0, 0, 0, -/* ----- */ -/* 34 */ 0, 0, 0, 0, -/* ----- */ -/* 38 */ 0, 0, 0, 0, -/* ----- */ -/* 3c */ 0, 0, 0, 0, -/* ----- */ -/* 40 */ 0, 0, 0, 0, -/* ----- */ -/* 44 */ 0, 0, 0, 0, -/* ----- */ -/* 48 */ 0, 0, 0, 0, -/* ----- */ -/* 4c */ 0, 0, 0, 0, -/* ----- */ -/* 50 */ 0, 0, 0, 0, -/* ----- ESC F1 F2 */ -/* 54 */ 0, 0, 0x01, 0x02, -/* ----- F3 F4 F5 */ -/* 58 */ 0x03, 0x04, 0x05, 0, -/* ----- */ -/* 5c */ 0, 0, 0, 0, -/* ----- */ -/* 60 */ 0, 0, 0, 0, -/* ----- F6 F7 F8 F9 */ -/* 64 */ 0x06, 0x07, 0x08, 0x09, -/* ----- F10 */ -/* 68 */ 0x0a, 0, 0, 0, -/* ----- */ -/* 6c */ 0, 0, 0, 0, -/* ----- F11 F12 F13/PRNT SCRN */ -/* 70 */ 0, 0x0b, 0x0c, 0x0d, -/* ----- F14/SCRL LCK */ -/* 74 */ 0x0e, 0, 0, 0, -/* ----- */ -/* 78 */ 0, 0, 0, 0, -/* ----- HELP/PAUSE DO */ -/* 7c */ 0x0f, 0x10, 0, 0, -/* ----- F17 F18 F19 F20 */ -/* 80 */ 0x11, 0x12, 0x13, 0x14, -/* ----- */ -/* 84 */ 0, 0, 0, 0, -/* ----- FIND/INSERT INSERT/HOME */ -/* 88 */ 0, 0, 0x23, 0x24, -/* ----- REMOVE/PG UP SELECT/DELETE PREVIOUS/END NEXT/PG DN */ -/* 8c */ 0x25, 0x38, 0x39, 0x3a, -/* ----- KP 0 */ -/* 90 */ 0, 0, 0x6b, 0, -/* ----- KP .
