.net 2003 only builds for .net framework v.1.1???

I tried to use System.IO.Ports, but it said the namespace couldn't be found. It maybe a namespace in .net framework v2.0.

On my machine I have both v1.1 and v2.0, is there a way to configure .net 2003 running on .net framework v2.0?

If you want to find out if a class/namespace exists in a certain framework, you should look at MSDN, its as easy as searching for the namespace/class in the search box;)
http://msdn2.microsoft.com/en-us/lib....io.ports.aspx
As you can see, it only exists in 2.0 and 3.0.

If you'd like to take advantage of the extra contents of .Net 2.0, you'd have to upgrade to 2005 or 2008:)

Though there isn't any direct support for serial ports under 2003, there are still serial port classes available. I found this link where I posted three classes that I had found as freeware based on a thread by Wossname.

I used one of these three under 2003, and found it easy to use and entirely functional. By this point, I don't remember which one I used, but maybe I mention it in the thread.

Thank you very much!

The big picture is clear now and I will have a try.
