Abstract

The invention concerns a data transmission device (2, 3), which is arranged between a data terminal device and a transmission network, and is controlled by control commands, which it receives from the data terminal device (DE) and which are inserted in the data stream to be transmitted. According to the invention, means (5, 9) are available to recognise whether pauses are included in the incoming data stream. A buffer memory (9) stores the most recently arriving data words, and, after a pause has been recognised, the data words which were most recently written to the buffer memory are compared with code words which signify a command to switch from a data transmission operating mode to a control operating mode. <IMAGE>
