I try to implement a direct port access. If this also leads to access

Accessing ports is limited to ports < 03ffh, more ports cannot be
released with fpioperm. This means to me, successful serial port access
on higher addresses cannot yet be implemented with fpc. If this policy
can be ruled out, let me know.
This has nothing to do with fpc. Maybe you should read the ioperm man
page and you might start to understand things.
I am new to linux and wrote only small things for MS-DOS before. As far
as I could read on the internet, fpc uses ioperm and iopl, and I will
try to use iopl to get access to the ports I want to use. The problem is
indeed the rights management, as far as I can read on several web pages,
which addresses my technical problem. The rights management cannot be
ruled out by an application like I intend to write. But I can deal with
it, I hope so far.
My posts to this list are not written against any person. My problem is
not an interpersonal problem, but a technical question, and I try to
find a good answer to it.
