<p>A method for automatically determining the baud rate of a serial data transmission comprises the steps of setting a receiving device to a first baud rate, processing (65) a first data word received by said receiving device and possibly further information to determine said baud rate of said data transmission, possibly setting (68) said receiving device to a second baud rate in order to enable said receiving device to find the beginning of a subsequent data word in said serial data transmission, and possibly setting (74) said receiving device to said determined baud rate. A corresponding apparatus and a mobile telephone each employs this method. The invention provides an autobauding function which causes little expense in terms of hardware and processing time, and which will correctly synchronize with the serial data transmission even if the transmitted data words immediately follow each other.</p> |
