Modem Configurations - Diamond SupraExpress 56e Manual

You will probably use only one set of communication standards, unless you make international
calls.

Factory Default, Active, and Stored
There are three types of modem configurations: factory default, active, and stored. (The stored
configuration Feature #120 is available only on certain modem models.)
Factory Default:
Active Configuration:
Stored Configuration:
Loading the Factory Configuration
To load the factory default configuration, issue AT&FØ (for IBM or compatible computers) or
AT&F1 (for Macintosh computers). This tells your modem to use AutoReliable mode, hardware
handshaking, and CONNECT XXXX messages that reflect the computer's rate. (If you have
NVRAM, issue AT&W to store the configuration so it loads automatically when you turn on the
modem.) The factory default configuration works for most situations.
The factory default configuration settings include other commands described below:

ODEM ONFIGURATIONS
Before your modem left the factory, it was set up to act a certain way. For example, it returns
full-word Result Codes and waits for a dial tone before dialing. Factory configurations differ,
depending on what kind of computer you are using and whether you need error correction and
data compression. These settings comprise the "factory default configuration."
The factory default configuration is stored in the modem's permanent memory (called
firmware ROM). Whenever you turn on your modem, it loads the factory default configuration
into the active configuration area.
The active configuration is the one you use when you have your modem turned on. It is stored
in the modem's temporary memory (called temporary RAM).
Changes made to the active configuration are lost when you turn the modem off. If you want
the changes to be in effect when you turn on the modem the next time, you can add any
changes from the factory defaults to your software initialization string. However, many
applications issue AT&F as part of their initialization, so even if you save your active profile,
the application's initialization will reset the factory defaults.
If you have a modem with a nonvolatile random access memory (NVRAM), you can save the
active configuration. It becomes a stored configuration residing in the modem's NVRAM.
(Issue the ATi10 command from your software terminal mode to display the list of features
your modem supports. NVRAM is Feature #120.)
