Abstract
A method for controlling data transmission in a wireless V.24 data transmission system operating between a data terminal and a data transmission device. The data transmission system has a first data transmission apparatus connected to a data terminal by means of a V.24 cable and a second data transmission apparatus also connected to a data transmission device by means of a V.24 cable. An air interface may be used for wireless telecommunications in order to control transmission of control commands or control information for the data transmission device from the data terminal to the data transmission device. Recognizability of control commands or control information for the data transmission device is ensured, once a time-critical control command is made known in the data transmission apparatuses. After transmission has been completed on the transmission path between the first data transmission apparatus and the data terminal, the time sequence of the transmission of the control command on the transmission path between the second data transmission apparatus and the data transmission device is identically reconstructed, despite any asynchronous data transmission caused by the air inte…
