}     Function 6F01H of Interrupt 16H (as documented somewhere in the DOS BIOS
}reference) lets you set both the pause before the "typematic" repeating begins
}and the rate of repetition.

Never heard of function 6F01h, but this one will work on recent systems:

INT 16 - KEYBOARD - SET DELAYS (Jr,AT model 339,XT286,PS)
        AH = 03h
        AL = subfunction
            0 reset typematic (PCjr)
            1 increase initial delay (PCjr)
            2 increase continuing delay (PCjr)
            3 increase both delays (PCjr)
            4 turn off typematic (PCjr)
            5 Set typematic rate (AT or PS/2)
        BH = 00 - 03 for delays of 250ms, 500ms, 750ms, or 1s
        BL = 00 - 1F for typematic rates of 30cps down to 2cps
