Event interrupt in C++ (Visual Studio)

[anhnha]

I am using a PC based software (MFC app) for image processing. The software uses serial communication to communicate with other devices. Now I want to use event interrupt. Each time there is a character received, an interrupt is raised.
Could you give me some ideas how to do that in C++?
Actually, I don't have much experience about this?
Thank you.
