title: Listening to Serial Com Ports that are In use
body: <p>I'm dealing with some legacy systems that are using RS232 to communicate with peripherals. I'm not very experienced with COM interfacing. I have some code that can open and use COM ports, but it can't open ports that are used by other applications. I need to black box the packets so that we can use the same protocol for updated communications.</p>
  
  <p><strong>Is there any way to "middle man" incoming packets to an open COM port and detect what packets are being sent?</strong> I'm using .NET, but I'm open to any type of solution.</p>
  
  <p>(I found <a href="http://com0com.sourceforge.net/" rel="noreferrer">this</a> out there, but I don't think this will work for me.)</p>
