5. Does your modem command set include a test for V.42 error correction at the
remote modem (often called “Auto-Reliable Mode”)?
If Yes, disable this test. You can use sample configuration files
/usr/share/modem_m0.cfg or /usr/share/modem_m1.cfg as models to help
you create a file for your particular modem. See “Customizing the Modem
Configuration Files” on page 180 for more information. Go to step 7.
If No, go to step 6.
6. Does your modem respond to:
AT&F reset command
or
AT&F
n
reset commands, where
n
can be 0, 1, and so on?
If AT&F, configuration file modem_f.cfg is recommended.
If AT&F
n
, configuration file modem_f0.cfg or modem_f1.cfg is recommended,
depending on which provides the hardware flow control profile.
7. You have completed selection of the configuration file.
If your modem configuration selection is not available in the Service Processor
Modem Configuration Menu, you must access it through the Configure Remote
Maintenance Policy Service Aid.
If you find it necessary to adjust any of these configuration files, use the manual
provided with your modem to accomplish that task. It is recommended you
select settings that enable hardware flow control and respond to DTR.
Note: Some older modems do not respond to the X0 or &R1 commands. Edit
out these commands from the modem configuration file if yours is such a
modem. See your modem manual for more information.
Some modems, such as the IBM 7857-017, are not designed for the paging function.
Although they can be used for paging, they return an error message when they do
not get the expected response from another modem. Therefore, even though the
paging was successful, the error message causes the Service Processor to retry,
continuing to place pager calls for the number of retries specified in the Call-Out
Policy Setup Menu. These retries result in redundant pages.
