The ISL is a little known trick for making your internet, sound cards, cable modems, and other computer attachments run faster. What you do is plug them into the 9-pin serial connection of your computer, but first bridge pin's 7 and 8 together causing an infinite speed loop... Makes them go fastah!
Dude, my new soundcard works so much better now that I got it caught in an ISL - Infinite Speed Loop!
