Using the Serial Ports in Visual C++ - ee

members.ee.net

Some have a single communication port (COM1). Here, the Windows API is discussed and used to operate the COM ports. The serial ports are accessed through any version of Windows and Visual C++ by using a few system application interface (API) functions. An example of a short C++ function that accesses the serial ports is listed in Example 1.
