     One of the posts that keeps reappearing in the programming newsgroups is how to enumerate all the serial ports installed. The 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. .

Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
