EnumSerialPorts v1.02 - Enumerating Serial Ports

Introduction

Features

• Simple C style function interface.
• The code works on both Windows 95/98 and NT.
• 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.

History

• Initial Public release.

v1.01 (23 February 1999)

• Code now uses QueryDosDevice() if running on NT to determine which serial ports are available. This avoids having to open the ports at all. It should operate a lot faster in addition.

V1.02 (12 December 1999)

• Fixed a problem in the Win9x code path when trying to detect deactivated IRDA-ports. When trying to open those, you will get the error-code ERROR_GEN_FAILURE.
