For windows:

Because the SetKeyboardState function changes the input state of the calling stream, rather than the global login state, the application cannot use SetKeyboardState to set the NUM LOCK, CAPS LOCK or SCROLL LOCK (or Japanese KANA) indicator on the keyboard. They can be installed or cleaned using SendInput to simulate keystrokes.
