title: c# SerialPort MultiDrop connection
body: <p>I have been reading up on the web and cannot find any information on working with a RS485 MultiDrop connection in c#</p>
  
  <p>To give a bit of insight. I have written an application to communicate with a Serial device using the MODBUS RTU protocol. Now the client has informed me there devices may be hooked up using multidrop communications links. Being a novice when it comes to working with serial devices I am a bit lost here. </p>
  
  <p>My question is simply: Where do I start? a Google search has thus far only produced hardware converters and wikipedia entries for different Serial Communication standards. </p>
  
  <p>Thanks! </p>
