Thread: Send and Recive Information through the serial Port RS232

From what i know you will use System.IO.Ports.SerialPort class.

Info on how to use this class with some examples can be found here http://www.codeproject.com/csharp/Se...munication.asp.

On a side note if you want to attempt to do it trough parallell port then I'd suggest the use of PortAcces.Output() which can be used trough a dll ... more info at: http://www.codeproject.com/csharp/cspplcds.asp

I forgot to mention that im using Framework 1.1 an the visual studio 2003 , so that class that u mention on top is not on this version.

SUMMARYOut-of-the-box, the only way of coding RS232 serial communications applications in the .NET environment is to import the outdated and somewhat limited MSComm ActiveX control. This article describes the development of a lean, multithreaded, and modern RS232 base class library in C# managed code. The library uses Platform Invocation Services to interact with the Win32 API directly. Application programmers can use the library from any .NET language through inheritance; the article explores examples written in C# and Visual Basic .NET.

After some googling, they use CreateFile ( a win32 function ) , anyway I think you should take a look at that article as a start.
