Have you tried the "Serial Communication Application Sample" Microsoft provides with its .NET Framework samples?

That is the pseudo-URL you get when you are in Visual Studio help.

If you are in VS2008 help ("Microsoft Document Explorer") and type that into the textbox at top, it should take you right to the article.  Or, if you have a different installation, you could google it.
