If that which interests you is just the keyboard, then you don't need an
interrupt
handler.  You should look at Ada.Text_IO.Get_Immediate which can wither
be called so as to not return until a key has been pressed, or to return
immediately with a Boolean object set to indicate whether a new character
is available.

If you're looking for keyboard scan codes -- e.g. to get non-character inputs
such as funcion keys or the change of state of the Shift, Alt, or Ctl keys,
then you have an OS-dependent problem.
