Remarks
Overwrite this method in derived classes to react on ADS Read Write confirmations. The Default implementaton just returns NoError. Because the Confirmation is the last step in the ADS communication an Error will just be logged, but not processed any further. For a functional AdsServer, this confirmation handler doesn't need to be overloaded!
