The best and most accurate way to achieve this certainly is to modify the firmware. I don't know if the stock firmware provides enough information for this without modification. You'll probably have to dig through the specs wiki. -- Greetings Michael. _______________________________________________ b43-dev mailing list [email protected] http://lists.infradead.org/mailman/listinfo/b43-dev
