Serial port communication

[nbaker76]

Has anyone interacted with a RS232 (serial port)? I've found a couple of examples of how to do it in VB, but I really need to know how I can do this using C#. Studio 2005 is going to have an assembly System.IO.Ports that will handle this, but for now (using .NET 2003) everything I have found says I need to write a wrapper, but I can't really find an explanation of what I need to write. Basicially I just need to send a voltage signal to an RS232 port. Does anyone have any ideas how to do this?

Thanks

This article has info on how to talk to a COM port and a class called Rs232 written in C# that works as your wrapper:

It helped a lot, but I am still not there all the way for sending the right voltage.
