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

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
