Apple Macintosh 6500 - Manual (Page 89)

Modem cables (for external modems)
If you purchase an external modem that is designed for use with a Macintosh,
it will probably include a Macintosh-compatible modem cable. If you have to
purchase a cable separately, make sure it supports hardware handshaking, a
protocol that controls the flow of data between computers. Also make sure the
cable has a rounded connector that will fit the modem port on the back of
your computer (labeled with a W icon). A cable designed for use with a
Windows- or DOS-compatible computer won’t work with your Macintosh.
Bundled software
Many modems include bundled software, such as fax software, a terminal
emulation program, and free trial membership software for online services. If
you can’t decide between two comparably priced modems, pick the one that
comes with the best bundled software.
Connecting a modem
To connect an external modem, follow the instructions in the manuals that
came with your modem. To install and connect an internal modem card,
follow the instructions in Appendix B of this manual for installing
communication cards as well as the instructions in the manual that came
with the card.
Note: Some modems have a single phone jack, while others have two. If your
modem has only one phone jack, consider purchasing a line splitter at an
electronics supply store. A line splitter enables you to plug your phone and
your internal modem into the same jack at the same time. (By the way, you
can keep your answering machine connected to your phone, even if your
phone and modem share the same telephone line.)
IMPORTANT When connecting a modem, make sure you connect the modem to
an analog phone line—the kind used typically in homes. Connecting to an
ISDN line could damage the modem.
IMPORTANT Disconnect your modem from the phone jack during lightning
storms. This will prevent a destructive voltage overload from damaging
the modem.
