Suitable header file for serial port or RS232 communications

[infineonintern]

Does anyone know which header file is suitable to be use to generate rs232 communication between two PCs or to set the serial port.

What i am doing currently is to connect two PC via null modem and allow one PC to be "talking" meaning sending data to the other PC which is "listening" by monitoring the data sent.

I have tried to use bios.h header file but it is not inside the include folder of Microsoft Visual Studio 2005 C++.

I am very new for this kind of PC and communications stuff and hope someone can help. The only software that i have is Microsoft Visual C++.

Do help!

I don't think you need any specific header other than windows.h.

If your using Microsoft Visual Studio 2005 C++ - You'll need to download the "Windows Platform SDK" to use the windows.h - Otherwise grab Visual Studio 2008 - It comes with the Platform SDK
