Set Repeat Rate (Interrupt 16H Service 3)
Use with AT and PS/2

Register Contents on Entry
AH-3
AL-5
BH-Repeat Delay (msec.)
   00h - 250
   01h - 500
   02h - 750
   03h - 1000
BL - Repeat Rate (Characters per Second)
   00h - 30.0
   01h - 26.7
   02h - 24.0
   03h - 21.8
   04h - 20.0
etc, etc down to
   1Dh - 2.3
   1Eh - 2.1
   1Fh - 2.0

Example:
; Change the repeat rate to 10 characters per second and
; the delay to 500milliseconds.
MOV AH,3
MOV AL,5
MOV BH,1
MOV BL,0Ch
INT 16h
