A connection device comprises a first physical device, a first device driver layer, a first interface abstraction layer, in which is embedded a first software support layer, a data core, a second interface abstraction layer, in which is embedded a second software support layer, a second device driver layer and a second physical device. A command and control module is connected to each of the physical devices and to the data core. Data and commands passing from the first device driver layer to the data core are removed of protocol-dependent information.
