This is a matter that is highly dependent on the platform, both
hardware and Operating System.

Some questions to be answered are:

   1.  Are you looking to manipulate the hardware directly, e.g.,
        by reading and writing values from and to registers?
        Some OSs will not allow user-level code to do these
        operations.

   2.  Are you looking to access the RS-232 port through
        Operating System services -- e.g., by treating the
        device as a file to which one can write, and from which one
        can read?

With more details of what you're trying to accomplish, an
appropriate solution can be suggested.
I have done serial port IO on a number of platforms and OSs,
all in Ada95.
