METHOD FOR CONTROLLING DATA TRANSMISSION IN A WIRELESS V.24 DATA TRANSMISSION SYSTEM OPERATING BETWEEN A DATA TERMINAL AND A DATA TRANSMISSION DEVICE FOR DATA TELECOMMUNICATION

摘要

The invention relates to a wireless V.24 data transmission system operating between a data terminal and a data transmission device for data telecommunication having a first data transmission apparatus connected to th e data terminal by means of a V.24 cable and a second data transmission apparatus connected to the data terminal by means of a V.24 cable, wherein said apparatus may in turn be connected for wireless communication by means of an air interface. According to the invention, in order to control transmissi on of control commands or control information for the data transmission device from the data terminal to the data transmission device in such a way that recognizability of control commands or control information for the data transmission device is ensured, once advertising of the time critical contro l commands, e.g. the ESCAPE sequence, has been effected in the data transmissi on apparatus, the time sequence of the transmission of the control commands on the transmission path between the second data transmission apparatus and the data transmission device is identically reconstructed in the wireless V.24 data transmission system after transmission has been completed on the transmission path between the first data transmission apparatus and the data transmission device despite asynchronous data transmission caused by the air interface by observing the time information contained in the control command s (e.g. the pause time contained in the ESCAPE sequence).
