A Fritzbox has an integrated TR64 (SOAP) server which allows to query data and to change the configuration. The project has a Free Pascal (Lazarus) unit to access this API. The unit may be used with Delphi too. There's also a test application (Lazazus) to read the Fritzbox TR64 data and a Deskband to show some Fritzbox data in the taskbar (Lazarus).
