Configuration File Selection
Use this procedure to select a modem configuration file:
1. Is your modem an IBM 7852-400?
If yes, use modem configuration file
modem_m0_sp
, and go to step 7 on page 221
below.
Note: The IBM 7852-400 modem has dip switches on the right side of the unit. See
“IBM 7852-400 DIP Switch Settings” on page 222 for the correct switch
settings.
If no, continue with step 2 below.
2. Is your modem an IBM 7857-017?
If yes, use modem configuration file
modem_m1_sp
and go to step 7 on page 221.
Note: The IBM 7857-017 modem has two telephone line connections on the back
of the unit. One is marked LL (for Leased Line), and the other is marked
PTSN (for Public Telephone Switched Network). The service processor
expects to use the modem on the public network, so the telephone line
should attach to the PTSN connector. Also, see the note on page 91.
If no, continue with step 3 below.
3. Does your modem respond to the extended command set (prefixed with
&
)?
If yes, go to step 5. If no, continue with step 4.
4. Does your modem respond to either of the following:
v
ATZ reset command
or
v
ATZn reset commands, where n can be a numeral
If ATZ, configuration file modem_z.cfg is recommended. If ATZn, configuration
file modem_z0.cfg is recommended.
Go to step 7 on page 221.
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, this test must be disabled. Sample configuration files
/usr/share/modem_m0.cfg
or
/usr/share/modem_m1.cfg
can be used as models to
help you create a file for your particular modem. See “Customizing the Modem
Configuration Files” on page 221. Go to step 7 on page 221.
If no, go to step 6.
6. Does your modem respond to either of the following:
v
AT&F reset command,
or
v
AT&Fn reset commands, where n can be a numeral
