A Go Anywhere PlugBy
If you've bought a laptop modem recently, it probably came with a warning never to plug it into the digital phone systems found in many offices and some hotels. Even if these systems don't fry your modem, they won't let it dial. That can make the Konexx Konector 111 from Unlimited Systems Corp. (800 275-6354) a useful addition to any road warrior's kit. The $159 device, about the size of a pack of cards, plugs in between the handset and phone. You then plug your modem into the box and can safely connect using any sort of line.
