Hello,
        Kind of off-topic question. 

        I want to reset/set keyboard from my own interrupt handler
        (via irq 9), so I don't want/can't to use bios (or even dos)
        interface. This assumes a PC.

        Looking at kernel sources it seems to me, that reset of 
        keyboard would be 

             outp(0x60,0xFF);

        and if I would want to set CAPS_LOCK led, it would be something
        like this

             outp(0x60,0xED);
             sleep(1);
             outp(0x60,0x2);

        Yet it does not work. Can anyone hint me in right direction
        what I'm doing wrong? A 5 line example would be great. 
        I suspect it has something to do w/ timing, but not sure
        where the error is.

        The above example is from borland 4.5 for dos (under dosemu).
        (so it is emulated keyboard contoller, but it should not
        make differnce).
