For I/O, you may be thinking of seqeuntial or direct I/O, or streams. You can 
find the packages Ada.Sequential_IO, Ada.Direct_IO, and Ada.Streams.Stream_IO in 
the ARM, Annex A, which is quite readable:

For bit manipulation, you can use (packed) arrays of Boolean or modular types. 
The former existed in Ada 83 and the latter were introduced in Ada 95; both 
should be covered in any good text.

But it's better to talk about what you want to do than how you think you should 
do it. Sometimes you might find a better way to do something.
