You can commit the changes . I don't have commit privileges nor do I want them. Yes, I realize what you guys are trying to do. If you wish to preserve information write it down to a file when the application exits. During normal execution , is not a problem. I hate to preserve state information such as the one that you guys are asking and no it is not hard to implement, again is not a good practice to have at the driver level. Actually, it would not surprise if some of you may get battery back up for your favorite Bt848 based card to preserve its state between power cycles 8) All in all things are really shaping up 8) Have fun guys, Amancio >From The Desk Of Steve Passe : > Hi, > > >From a driver point of view , when the device gets open the device > >will be set to defaults values.
