SN65HVD75 :Carrier detect solutions for RS485

Part Number: SN65HVD75
Other Parts Discussed in Thread: PROFIBUS, SN74LVC1G123, SN74LV123A, SN65HVD3082E

Hello,

We would like to have carrier detect signal from RX data (we use RS485 half duplex and fieldbus 1 Mbits like Profibus). In fact we would like to generate this signal  in order to acquire RX frame and send them to  a spybus ... 

Do you bave solutions or TI products to generate this carrier dectect ( it could be logical components or  small 8051 or huart or Pic...).  It would be nice of you to advice us

Link to screen shot with RX  TTL signal RS485, and Carrier detect from an old component.
