Title: Keyboard (keyscan?) IRQ
Post by: MIRKOSOFT on December 27, 2009, 02:53 PM

Hi!

I have simple Q:

As I can modify vector of IRQ at $0314, is possible to modify vector to keyboard event IRQ?
'Cause I want to apply my IRQ to every keyboard event.

Thanks for every reply.

Title: Why keyb. IRQ?
Post by: MIRKOSOFT on December 27, 2009, 03:34 PM

I want to give to SHIFT LOCK function same as CAPS LOCK.

And there is the main problem:
When I recognize LOCK is pressed, I must reroute vector from SHIFT keytable to CAPS keytable.
And when occurs that LOCK is not pressed vice-versa...

I tried to do IRQ at vector $0314 and it seems that it not recognize every key - so, how to reroute the keyscan IRQ first to my test and after jump to original?

Thanks for every reply.
