title: How to emulate a serial port for testing
body: <p>I neeed to write a device emulator for testing purposes that connects through a serial port. I know there are some apps out there to do this, but that doesn't really help my curiousity, lol. I would like to know how in .net I could write a sniffer to watch the traffic in and out on a serial port. I'm also interested in what suggestions anyone has to accomplish my testing, but I want something in .net and not a 3rd party download.</p>
