EnumSerialPorts v1.0

Welcome to EnumSerialPorts v1.0, A simple MFC function to enumerate the serial ports installed on your machine.

Features

• Simple C style function interface.
• The code works on both Windows 95/98 and NT. The whole problem is that there is no standard Win32 API call which allows serial port enumeration. The approach that this code uses is calling CreateFile directly. If the port cannot be opened, the code examines the error code to see if it was accessed denied error in which case it knows that the port exists even though it could not open the port.
• The code is fully Unicode compliant and include Unicode built options in the workspace file.

Usage

• To use the function in your code simply include enumser.cpp in your project and #include enumser.h in which ever of your modules needs to make calls to the function.
• Your code will need to include MFC either statically or dynamically.
• To see the class in action, have a look at the main function in the module "main.cpp".
