How do I talk through the serial port using VB.NET?
While you could always do all the work yourself by using pinvoke down to CreateFile and ReadFile from the Win32 API, why make it hard on yourself? A quick search on MSDN turned up two libraries that you may want to consider. The first is John Hind's MSDN Magazine article, "Use P/Invoke to Develop a .NET Base Class Library for Serial Device Communications" ( http://msdn.microsoft.com/msdnmag/issues/02/10/netserialcomm/). The second is DualBrain's .NET layer that matches the MSCOMM32.OCX api if you're used to that. ( http://www.gotdotnet.com/community/workspaces/workspace.aspx?ID=0A680784-1D84-4E0A-8A62-9DCBCF79E1FB).
