Is it possible to set the typematic delay / repeat values on an XT system?
I've been searching around for a while and haven't found an answer to this except for a mention by Raymond Chen: The XT keyboard did not have a configurable autorepeat as far as I can tell.
For AT, PS/2 and even PCjr one can use INT 16h/03. What's weird about the PCjr one is that there's no ability to set specific amounts but you can increase or decrease them. I have a side curiosity about this: what happens when you reach the limit, does it wrap around or just stop increasing/decreasing?
