A Method of Real Time Communication on Serial Port Using Win32 APIs

This paper presents a method for real time communication on serial port which program with Win32 API and run under Win9X or above operating systems. By using of multithread, asynchronous I/O operations and events drive mechanism,the problem of real time communication on serial port which encounter in the computer surveillance and control systems work under 32bits operating systems, had being successfully solved. Part of the communication program codes are presented in the paper.
