Can't import System.IO.Ports

Can somebody please help me! This problem drives me mad!

I've got a small GPS-Reciever; very nice little thing.
Now I want to design a little program to connect to the reciever. I looked
on the internet for some help to connect to the COM-port. Just a little code
"Imports System.IO.Ports".

When I typed this code in VB.NET, it wouln't work because the namespace
"System.IO.Ports" cannot be found. In the references of the project is
already a version of "System.dll". This is the only version I've got.

Does anyone know what went wrong over here and how I can solve this strange
problem?

If I am not mistaken, System.IO.Ports is supported from up to version
2.0. If you are using version 1.1 then this namespace isn't there.

Hi,

Assuming you are using VB 2005, no I cannot explain it. Perhaps some sort
of bug. If you are using VS 2003, the you can download DesktopSerialIO from
my homepage (I also have a DecodeGPS dll that you may want to use). There
also is a VS 2005 version of DesktopSerialIO.dll that you can use as a
work-around. These all are free.
