Lines: 48 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Some time ago, Mike Ditto posted the source for a dynamic keyboard remapper for the UNIX PC (called "keyfix"), which changed the copy of /unix in core as the system was up and running. Its usage was: keyfix [ ]. Since these changes to the keyboard are usually permanent, I thought I'd do it the dirtier (and much faster) way of making permanent changes to /unix itself. The following uses adb and of course, a LARGE NOTE OF CAUTION: BACK UP YOUR /unix AND IF YOU MAKE ANY ERRORS, THEY COULD BE DISASTROUS TO YOUR SYSTEM!!!!!! So, if you wanted to execute the command: keyfix 0x25 0x7f 0xff 0xff 0 to change the Reset/Break key (0x25 in /usr/include/sys/kbd.h) to issue the break command when depressed without shift or ctrl, and be non-repeatable, you could instead do: adb -w /unix keymap+(8*25)?4x ?w 0x007f 0x00ff 0x00ff 0x0000 $q and you would get (in UNIX 3.51) the following confirming output: keymap+128: ff ff ff 0 swpulse+21a2: ff = 7f swpulse+21a4: ff = ff swpulse+21a6: ff = ff swpulse+21a8: 0 = 0 The corresponding address for the Del/Esc key is: keymap+(8*1b) The corresponding address for the space key is: keymap+(8*20) The corresponding address for the _/- key is: keymap+(8*2d) The corresponding address for the ?// key is: keymap+(8*2f) The corresponding address for the ^/6 key is: keymap+(8*36) ... and so on. I tried it out and it worked fine. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- David Solan Objective Programming Incorporated Post Office Box 123 Norwalk, CT 06856 Voice: (203) 866-6900 attmail: or -- 24 million Americans will die in the next 10 years without their seat belts on.
