    Tanks for the hint with the manpages. Ive read them.

    but i dont know yet what this means:

        int busy = nAck | nFault;
        int acking = nFault;
        int ready = Busy | nAck | nFault;

    Iam getting some errors during the build:

    inttest.c:27: `nAck' undeclared (first use in this function)
    inttest.c:27: (Each undeclared identifier is reported only once
    inttest.c:27: for each function it appears in.)
    inttest.c:27: `nFault' undeclared (first use in this function)
    inttest.c:29: `Busy' undeclared (first use in this function)

    Where is the problem ?

    Norman.
