Configuration File Selection

Use the following steps to select a configuration file:

1. Is your modem an IBM 7852-400?

If Yes, use modem configuration file modem_m0.cfg and go to step 7 on page 385.

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 387 for the correct switch

settings.

If No, continue with step 2.

2. Is your modem an IBM 7857-017?

If Yes, use modem configuration file modem_m1.cfg and go to step 7 on page 385.

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.

If No, continue with step 3.

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:

v ATZ reset command

v ATZ

reset commands, where

can be 0, 1, and so on?

If ATZ, configuration file modem_z.cfg is recommended.

If ATZ

, configuration file modem_z0.cfg is recommended.

Go to step 7 on page 385.

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 386 for more information. Go to step 7 on page 385.

If No, go to step 6.

6. Does your modem respond to:

v AT&F reset command

v AT&F

reset commands, where

can be 0, 1, and so on?
