the Num Key or direction key on the keypad. When users press

Num Lock status. If press the Num Lock key until 0.8 sec, then
the Host’s Num Lock status will be changed. This function is
designed for some special software, like Excel. Users can know
the Num Lock status on the screen and don’t need to care the

easily.
