   Please tell us which chip you use!            01/01/70 00:00      
      i must simulate ECU behavior,not a single chip            01/01/70 00:00      
         what is the bit rate and will this do            01/01/70 00:00      
            5 bps!            01/01/70 00:00      
               it will make the output 110 ohms            01/01/70 00:00
