Solved Setting scroll-lock with bios interrrupts

June 8, 2017 at 02:34:39
Specs: Linux x86_64
I can get shift states for scroll-lock, numlock, capslock, etc with ah=2, int 16h. Are there any interrupts that would set those states rather than just reading them?

✔ Best Answer
This external discussion might be of some interest to you:
There you'll find examples of enabling scroll lock, num lock and caps lock in x86 assembly. I cannot vouch for them, since I haven't tried, and they use routines other than those availbale through BIOS to do the work.
I also did a check on interrupt routines (as I'm sure you already have), and found no mention of setting these states through BIOS interrupts.

Thanks for that. Yes, I did look through the interrupt list, and didn't find any that did the job. I've since amended my program to do things a different way. But I'll take a look at the discussion anyway. It might give me some ideas for another day.
