Connecting an external modem
You can use a PC Card modem in your computer’s PC Card slot. For
information on connecting and using a PC Card modem, see the
documentation that came with your modem, as well as the “Using a PC Card
Modem” section earlier in this chapter, and the “Using PC Cards” topic area
of Mac OS Guide, available in the Guide (h) menu.
You can also connect an external modem to the modem/printer port on the
back panel of the computer. The modem/printer port is GeoPort compatible.
To connect an external modem, follow these steps:
1 Make sure the computer is in sleep or shut down.
2 Connect the modem to a power source and to the phone line.
3 Make sure the modem is turned off.
4 Connect the modem cable to the port marked with this icon:
5 Turn on the modem.
6 Wake or restart the computer.
7 Open the Chooser and select the icon for a network printer (such as LaserWriter).
You must select a printer to be sure that the modem/printer port is available
for the modem.
8 Turn off AppleTalk in the Chooser.
If you see a message, click OK.
Note: If you are using an Ethernet or infrared connection, you don’t need to
turn AppleTalk off.
The external modem is ready to use.
