kernel mode termios API's

Hi, We are having customized serial port driver, it always sets the baud to 9600 (by configuring UART BAUD_RATE register) on device file open, but not updating the termios structure. The python code(pySerial) reads the termios parameter for baud rate and only sets the baud rate if it needs to. So pySerial fails to work with this driver. Is there any kernel API to update termios structure about 9600 baud on driver device open? -- Thanks, Sekhar
