ABSTRACT:
A method of verifying the baud rate for communication of data by an Asynchronous serial device residing within a data processing system. The data processing system having a first Asynchronous serial device and a second Asynchronous serial device. The first and second serial devices are connected one to another for communication of data therebetween. The first and second serial devices are initialized with a common baud rate for transmission and reception of data, respectively. A test sequence pattern is created, and transmitted at the common baud rate from the first serial device to the second serial device. The second serial device transmits the received test sequence pattern back to the first serial device. The test sequence pattern is then verified as either valid or invalid.
