Modem tips and troubleshooting
If your modem does not make a call or a connection, try these procedures.
Make sure the modem is specified correctly in your communications
software.
The modem information you should provide in the setup portion of a
communications program includes the following:
m The modem port is Internal Modem.
m The modem’s name is PowerBook G3 Internal 33.6 or PowerBook G3
Internal Modem in the list of modems for a communications program.
m The modem initialization string is AT&F. (You may be able to use the
initialization string as the necessary setup information in a communications
program that does not have PowerBook G3 Internal Modem in its list
of modems.)
m If your communications program has an option for hardware handshaking,
turn it on. In some communications programs, this capability is called
“flow control”; the option to select is CTS & RTS (DTR).
Make sure the modem is selected in the communications program.
Depending on the software you are using, check the modem setup procedure
and verify that the PowerBook G3 Internal Modem or PowerBook G3
Internal 33.6 (they are the same modem) is selected. See the instructions that
came with your communications program for details on selecting the modem.
In some instances, you may need to select the modem in a control panel. For
example, if you are using Apple Remote Access 3.0 (or a later version), you
need to open the Remote Access control panel and specify the modem. If you
are using Apple Remote Access 2.1, you specify the modem in the Remote
Access Setup control panel.
If you do not have Apple Remote Access software installed, open the Modem
control panel and make sure the PowerBook G3 Internal Modem or
PowerBook G3 Internal 33.6 is selected in it.
