public: property virtual Boolean DeviceEnabled{
    Boolean get();

Remarks

When TRUE, the device has been placed in an operational state. If changed to TRUE, then the device is brought to an operational state. The appropriate device statistics and device information will be loaded, if needed. Exclusive-use devices must be opened and claimed before this property can be accessed. Shared devices must be opened before this property can be accessed.

When FALSE, the device has been disabled. If changed to FALSE, then the device is physically disabled when possible. Any subsequent input will be discarded, and output operations are disallowed.

Changing DeviceEnabled usually does not physically affect output devices. For consistency, however, the application must set DeviceEnabled to TRUE before using output devices.

DeviceEnabled is initialized to FALSE. State verification takes place in the basic and base classes for each device.

Thread Safety
