Stop! Don't plug your modem into the hotel-room telephone jack! If there's too much current on the line, it could fry your PC. Test the jack first with the Modem Saver Plus from Road Warrior International. This compact 3-ounce device tests the line and alerts you to excessive juice with a bright red light. If you get a green light (signifying a safe line), plug your PC into the Modem Saver, and it acts as a surge protector. Also available from Road Warrior is an international version, which filters foreign phone lines for tax pulses (intermittent signals that measure the amount of time you use the phone line and are potentially damaging to modems) and provides line-current and surge protection.
