Appendix B. Modem information
Modem features
Using a telephone network, a modem allows your computer to communicate with
other computers, fax machines, or telephones. For information about connecting
your modem to a telephone network, See “Connecting your modem to the
telephone network” on page 4-10.
Some IBM computers have a modem already installed. If your computer came with
a modem, all you have to do is connect the modem to a telephone line. (You may
also connect a telephone to the modem if it has two RJ11C jacks). The system
firmware is already configured to load the modem drivers and software once you
have made the connections.
If your computer does not have a modem but you intend to install one, see the
documentation that came with the modem for installation instructions and reference
information.
Attention!
Before you plug your modem into a
telecommunications system outside the country in
which it was purchased, make sure your modem is
designed to work with that telecommunications
system. Otherwise, you could damage your computer.
Read the guidelines in “Safety information” on page xiii
before you plug your modem into any
telecommunications system.
