Int 33H Function 1AH (26) Set mouse sensitivity

Sets the number of mickeys per 8 pixels for horizontal and vertical mouse motion and the threshold speed for doubling pointer motion on the screen. One mickey represents approximately 1/200 of an inch of mouse travel.

Call with:

AX = 001AH

BX = horizontal mickeys (1—32,767, default = 8)

CX = vertical mickeys (1—32,767, default = 16)

DX = double speed threshold in mickeys/second (default = 64)

Returns:

Nothing

Note:

See also Int 33H Functions 0FH and 13H, which allow the mickeys to pixels ratio and threshold speed to be set separately, and Int 33H Function 1BH, which returns the current sensitivity values.
