Author: oxygene Date: 2008-09-17 20:12:46 +0200 (Wed, 17 Sep 2008) New Revision: 3580
Modified: trunk/payloads/libpayload/curses/keyboard.c trunk/payloads/libpayload/drivers/keyboard.c Log: - unify keycodes for non-ASCII keys by using curses' codes and labels - fix ctrl-[a-z] - get rid of curses' ps/2 driver. uses generic one instead - #ifdef's around ps/2 keyboard handling and serial handling - add alt-key handling (necessary for german keymap) - flush keyboard controller buffer on init
