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.
