Go to the stdafx.h and delete following #define
#define VC_EXTRALEAN            // Exclude rarely-used stuff from Windows headers

This VC_EXTRALEAN exclude declaration for SetCommState. Eliminate this define.
You can write character to COM with WriteFile. You careat the handle of the port with CreateFile function and supply the name of the file "COM3"
