void Win_QextSerialPort::setBaudRate ( BaudRateType  baudRate  )  [virtual]

Sets the baud rate of the serial port. Note that not all rates are applicable on all platforms. The following table shows translations of the various baud rate constants on Windows(including NT/2000) and POSIX platforms. Speeds marked with an * are speeds that are usable on both Windows and POSIX.
