Customizing the Modem Configuration Files
You can create your own modem configuration files or modify the samples provided. After you customize
your modem configuration files, you
must
access them through the Configure Remote Maintenance Policy
Service Aid rather than from the service processor menus.
If you have already set up your serial ports, line speeds, authorizations, and telephone numbers from the
service processor menus, use the service aid to specify your customized modem configuration files.
If you have not already set up your serial ports, line speeds, authorizations, and telephone numbers from
the service processor menus, use the service aids to set them while you specify your customized modem
configuration files.
To disable Auto-Reliable Mode testing of the remote modem, use the sample modem configuration file
/usr/share/modems/modem_f.cfg
as a model that you can modify, as follows:
1. Find the necessary command in your modem manual.
2. Copy the
/usr/share/modems/modem_f.cfg
file to a new file with a different name (for example,
modem_fx.cfg
).
3. In the new file (
modem_fx.cfg
), change the line
Send "ATE0T\r"
to
Send "ATcccE0T\r"
where ccc is
the added command as specified in your modem manual, as follows.
Change the third line of each of the following stanzas:
v
condout
v
condin
v
ripo
4. Save the changes.
