| |
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). -- Adam http://www.eax.com The Supreme Headquarters of the 32 bit registers
