The system call 'sysi86' from UNIX System V/386 release 3.2 allows
to implement machine-specific functions.

I am looking for accessing directly a parallel port (without driver)
to read and set bits in the same way as simple in() or out() instructions.

I would find reasonable to do it with sysi86(). sysi86() can receive
command and arguments and I have some troubles to understand sysi86.h
and v86.h header files.

Has somebody experience with sysi86?
