Ada 83 had:

package LOW_LEVEL_IO is
   --  declarations of the possible types for DEVICE and DATA;
   --  declarations of overloaded procedures for these types:
   procedure SEND_CONTROL    (DEVICE : device_type; DATA : in out data_type);
   procedure RECEIVE_CONTROL (DEVICE : device_type; DATA : in out data_type);
end;

I don't know whether anybody actually implemented it, and it was
dropped in Ada 95 (it's not just obsolescent, there's no reference to
it at all).
