Accessories cannot share COM ports and should not share IRQs. When
accessories try to share settings, they will either not work properly or not
work at all.
3Com has set your modem to a default Plug and Play setting geared
towards Windows 95 users. In this configuration, the shunts used to set
your modem’s COM port and IRQ settings are hanging from single jumper
pins and will not affect your modem’s settings
Some communications software programs require a particular setting for
your modem. Now is a good time to read the software’s manual to
determine what setting is required.
How to Change the Modem’s Settings 1. Always touch an unpainted metal part of your computer (the back is
usually unpainted) to discharge static electricity before handling the
modem. Static can damage your modem.
2. Take the modem out of its plastic bag.
3. Find the COM and IRQ jumper shunts (small black plastic pieces) on
your modem’s jumper pins (refer to the diagram).
