SERIN incorrect baud rate detection and action

Hi,
I've been busy making a NMEA Heading repeater . I'm using the SERIN timeout option to flash the display when the NMEA sentence is lost ( disconnected wires etc). This is working fine. However, if I change the baud rate of the 'Talker' (Transmitter) the SERIN command appears to be simply ignored. Is this correct or should timeout also apply to incorrect baud rate ?
Thanks for any suggestions.

The timeout applies to lack of data received. Receiving data, which is wrong baud rate, corrupt, garbage or noise and is otherwise ignored, will reset the timeout and will prevent it from activating.

Thanks hippy. Is there anyway the resetting of the timeout can be detected so that I can get a flashing display for incorrect baud rate ?
Thanks

The timeout is entirely internal and its behaviour cannot be overridden or altered.

Okay thanks Hippy.
