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 via the
Configure Remote Maintenance Policy Service Aid rather than from the Service
Processor menus.
Note: If you have already set up your serial ports, line speeds, authorizations and
telephone numbers from the Service Processor menus, specify your customized
modem configuration files from the service aid.
If you have not already set up your serial ports, line speeds, authorizations, and tele-
phone numbers from the Service Processor menus, you may set them up with the
service aids 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 to modify.
1. Find the necessary command in your modem manual.
2. Copy /usr/share/modems/modem_f.cfg 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 "ATET\r" to Send
"ATcccET\r" where ccc is the added command found in your modem manual.
Change the third line of each of the following stanzas:
condout
condin
ripo
4. Save the changes.
Use this new modem configuration file as described earlier in this section.
