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.
