A further link gives its incomplete definition:

    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;

Also, the casing is funny.
