PCM-7130 is targeted to be the embedded device for web-enabled and
data-acquisition systems. It is built-in with Watchdog timer and LCD on-
off control. Users can access these resources by writing windows pro-
grams with WIN32 API. PCM-7130 is built-in the WDT driver to allow
users to enable/disable Watchdog timer and LCD on-off control. Users
should use WIN32 APIs to access them. The driver name is "WDT1:".
The programmers must open this driver before using the resources. Then
programmers could use DeviceIOControl functions to enable/disable
Watchdog timer and LCD on-off control. At most 5 applications can
