3. To change the COM port and IRQ settings,
you need to reposition the jumper shunts on
the COM port and IRQ pins. To do this, lift
the jumper shunts off the pins.
TIP: Grasp the jumper shunts with
a tweezers or needle-nosed pliers. DO
NOT grasp too firmly, as you may crush
the jumper shunts. If a jumper shunt
seems stuck, gently rock it back and
forth as you lift. Do not touch any other
part of the modem or your computer
with the tweezers/pliers. A jumper
shunt needs to be sitting on both
jumper pins in order to effectively set
the modem to the desired setting.
