High level access to I/O ports

Hello,

Is there a high level class or collection of procedures and functions that
gives access to communication ports such as serial, parallel, and USB ports,
and allows them to be written to or read from as if they were a Pascal file
or a Delphi stream? Ideally one should be able to open a file or a stream
passing the opening routine the name of a port instead of the name of a
file, and then handle the file like any other unidirectional file.

Thanks for any guidance.
