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.
so you must use a very special serial hardware which is located on io
address higher than $3ff. Seems unlikely to me. In your former post, you
tried to access io address 1000 (decimal) this is $3e8 (hexadecimal) and
should be an ordinary COM3. May be you are mixing up decimal vs.
hexadecimal notation.
