Regional Differences

Two connectors on the computer vary by region: the 25-pin
connector and the RJ-11 jack. These connectors are used for
modem and cellular phone connections.
Some computer models with an integrated modem feature both
an RJ-11 jack and a 25-pin connector.
Some computer models with an integrated modem feature only
an RJ-11 jack.
Some computer models, which can be used with an optional
PC Card modem, have neither an RJ-11 jack nor a 25-pin
connector.
However, all models can have modem functionality in all regions.
For information on using an integrated modem, using an optional
PC Card modem, and connecting an integrated modem to a
cellular phone, refer to Chapter 8, "Using a Modem."
