            Hi,
            I look in the parport book and see we could perform write and read.
    Wouldn't it be possible to add read/write operations such as reading a
    string of long ( insl) or word (insw)
    In fact, I think it could be useful to "implement" via ioctl call all the
    in/out possibilities ie
            inl,inw,inb,insw,insl,insb
            outb,outl, outw,outsb, outsl, outsw
    because, when the external device support these "instructions", you can go
    faster ( up to 1.6 Mo/s in insl)
