Customizing the Modem Configuration Files
You can create your own modem configuration file(s) 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 SP menus.
Note: If you have already set up your serial ports, line speeds, authorizations and
telephone numbers from the SP 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 telephone
numbers from the SP 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 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:
– condout
– condin
– ripo
4. Save the changes.
Xon/Xoff Modems
Some early modems assume software flow control (Xon/Xoff) between the computer and
the modem. Modems with this design send extra characters during and after the transmitted
data. The Service Processor cannot accept these extra characters. If your configuration
includes such a modem, your functional results may be unpredictable.
The sample modem configuration files included in this appendix do not support these
modems, so custom configuration files are necessary. Anchor Automation 2400E is an
example of such a modem.
If you experience unexplainable performance problems that may be due to Xon/Xoff
characters, it is recommended that you upgrade your modem.
