SERIES II INTELLIGENT DATA/FAX MODEMS
5.4.4 Configuration and Default Storage
Commands
Store Configuration & S-Register Parameters
in Non-Volatile Memory &W
The Series II Modem can store configuration parameters and S-Register
values in its nonvolatile read/write Random Access Memory (RAM)
memory. The &W command does this, which prevents any re-
configuration from being lost on a power-down or Reset (ATZ)
condition.
&W0 (or AT&W) causes the Modem to store your customized AT
command settings and S-Register values in its nonvolatile RAM. &W0
also sets the modem so that it reads your customized settings stored in
nonvolatile RAM when powered down or reset. (The &W0 command
only changes the settings stored in nonvolatile RAM that you specifically
intend to alter. All other default parameters are applicable.)
&W1 causes the Modem not to store your customized settings to
nonvolatile RAM so that, after powering down or resetting the modem,
it reads the factory default settings stored in ROM.
Loading Factory Defaults &F
The &F command provides a choice between customized configuration
settings in RAM and the factory default configuration settings in ROM.
The &F8 and &F9 commands define the function of the &F command.
The Series II Modem is shipped from the factory with a pre-configured
set of command and S-Register default settings. This set of factory de-
faults can be recalled by issuing the &F command.
In addition to being able to recall the factory-installed defaults, the &F
command can also recall those defaults stored under &W0.
This is done using the &F9 command. If you have stored parameters
with the &W0 command and wish these settings to always be used as
your defaults, you would enter &F9&W0.
To return the &F command to read factory installed defaults, enter
&F8&W0. &F8 is the factory default.
