    Hi Jeff,

    that of course is also no good reason and it should be changed in
    the backend or sanei_pio. If I remeber right single port permissions
    can be set by fcntl so that a user process can access the releavnt ports.
    Hm, is it possible to create a separate process with SUID bit set that
    sets the port permissions so that your backend can work with user permissions?

    Bye
    Oliver
