    "About a RS485 ioctl: could you consider the attached files which are
     already in the Linux kernel (in include/asm-cris).  They define a
     TIOCSERSETRS485 (ioctl.h), and the data structure (rs485.h)
     with allows to specify timings. Sounds just like what we want ?"
    
    and he's right: sort of. Rework the structure to use flag bits and make the
    time delay a fixed sized field so we don't get 32/64bit problems. Add the ioctls
    to x86 so that people know what to add to their platform of choice.
