They wer very useful, specially ctrl2cap from sysinternals. I also found another example in the Four-F kmdkit ( \examples\advanced\KbdSpy ). I write my own filter driver for the keyboard, but, during debugging, I noticed that it isn't able to filter keys used in softice (I think it's normal). How can I do to solve this problem? I know I can control several things sending commands to I/O ports, but I would like to not use "in" and "out" instructions. Thanks

Edited by floppy: If I cannot do anything about it, can anybody explain why? I would like to go deep in this stuff. Thanks for all.
