        They _may_ do that.  I do not use all of the other flavours so I can
        not say authoritatively if they have a 'BSD' defined or not.

        No, and that is the key part of the problem.   FreeBSD for example
        does not seem to have (that I can see) a way to issue general commands
        to ATAPI devices - only SCSI devices.

        Ah, but what about systems that are not GNU/Linux based and which do
        not have the 'SEND_CDROM_PACKET' ioctl call?   

        It is not just for 'scsi' devices though - it is for ATAPI devices as 
        well.

        It is that lower level "cdrom driver for the actual architecture" that
        I am thinking about.   Somewhere there must exist a layer of software
        that translates 'SEND_CDROM_PACKET' into something like (to use
        my system as an example) 'ioctl(fd, SCSIRAWCDB, &suc)'

        All that the 'libdvd' module did was translate:

        ioctl(i_fd, DVDIOCREPORTKEY, &auth_info)
        ioctl(fileno (_obj->fd), CDROMREADTOCENTRY, &tocent)
        ioctl (fileno (_obj->fd), CDROMREADMODE2,&buf)
        ...

        into:

        ioctl(fd, SCSIRAWCDB, &suc)

        with the 'suc' structure set up appropriately.

        Ok - I'll be here (or at home actually :-)).   What's one more 
        program to follow and test? <grin>
