Hello All,

The requirement is simple. I want to access serial port and do read and write operation on it.

Please help me

Depending on what you are trying to do take a look at the functions

Code:

---

BuildCommDCB()
ClearCommError()
CreateFile()
EscapeCommFunction()
GetCommModemStatus()
GetCommState()
GetCommTimeouts()
GetOverlappedResult()
ReadFile()
SetCommMask()
SetCommTimeouts()
WaitCommEvent()
WriteFile()

Additionally, the MSDN provides a detailed article about serial communication in Windows. Open MSDN, choose Index and type "Serial Communications". There are several subitems, choose 'Win32'... (it's also available online).

You could use JH.CommBase. Try looking at this article http://www.codeproject.com/csharp/freakshow.asp
