Netopia Firmware 4000-Series - Manual (Page 193)

Line Backup 7-5
Note:
• The modem cable should have a standard DB-9 female connector to connect to the console por t. This is the
standard type of modem cable connector.
• Macintosh users who use a USB-to-serial adapter to connect to the console serial por t can use a modem in
Modem/Auto mode. However, your terminal emulator software will not function in this mode via the USB
adapter, due to the pin assignments in the adapter. For console management access, Macintosh users should
use Console Only mode.
■ If you select Modem/Auto, you can select its Data Rate from a pop-up menu, edit the Serial Modem
Init String, if necessar y, and enter your local Serial Modem Directory Number.
Changes to Serial Por t Mode take place after a reboot. This is not automatic. You may continue to con-
figure these settings, and after you are finished, you must reboot the router manually. See
“Restar ting
the System” on page 11-12 .
■ Press Escape twice to return to the WAN Configuration screen, and select Advanced Connection
Options, then Backup Configuration (shown on
page 7-5 ).
