587 | The watchdog utility is used with hardware or software watchdog |
588 | device drivers. It opens the specified watchdog device special file |
589 | and periodically writes a magic character to the device. If the |
590 | watchdog applet ever fails to write the magic character within a |
591 | certain amount of time, the watchdog device assumes the system has |
592 | hung, and will cause the hardware to reboot. |
