Facebook LED blink on new notifications and messages

Step 3Download and configure the LED blinker

Download and configure the LED blinker
Download the LED Blinker from here, and unzip it somewhere.

Open Device Manager (you can do that by pressing WindowsKey+R and typing devmgmt.msc in the window that comes up), double click on Ports (COM & LPT), and then double click on your parallel port (it is usually listed as ECP Parallel Port or Printer Port or something similar).
On the new window that comes up, click on the Resources tab and note the first part of the I/O Range setting (check the attached screenshot). *

Once you have that, go to the folder where you unzipped the application, and open the address.txt file. Replace the contents of that file with the address you noted above (again, check the attached screenshot), and save it.

Once that's done, double click on LEDBlinker.exe to open the application (note: On Windows Vista/7 you must run it as an administrator for the first time!). You won't see anything, but you can verify that the program is running by looking for it in the Task Manager. If you have a firewall, it might warn you that the program is trying to listen on port 4012. You must allow it for the program to work (for more information check step 1).

Note: If you are getting an error when you run the application saying that it can't find mswinsck.ocx, then download it from here, and place it in the same folder as the program. It should work then (again, if you're using Windows Vista/7 you'll have to run it as an administrator for the first time).

*: If there are more than one I/O Ranges, then try them all until you find the one that works. Make sure you terminate LEDBlinker.exe via the Task Manager every time you change address.txt.
