Abstract
In 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 the 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, the apparatus may in turn be connected for wireless communication by means of an air interface. In order to control data transmission in such a way that baud rate changes can be easily detected, the baud rate is detected by the first data transmission apparatus while the autobauding function is activated in the first data transmission apparatus and in the data transmission device. The baud rate is transmitted by signaling to the second data transmission apparatus and is regulated therein parallel to the command data (AT commands) to be sent.
