Loading The Factory Defaults (&F) - US Robotics COURIER User Manual

COURIER HIGH SPEED MODEMS
You'll find a list of NVRAM options and factory settings in
Appendix B. You can also display them by selecting option 5 of
-
-
the I (inquiry) command: -
ATl5 <Enter>
If you've sent the modem commands to change settings
throughout your session and want to save your current configu-
ration, send just the &W command. The current settings are
saved.
AT&W <Enter>
You may also specify the entire configuration in a single com-
mand string that ends with the &W command. The following
example sets the modem for the current session and stores the
configuration in NVRAM.
AT X4 &81 &H1 M3 &W <Enter>
After sending a configuration to NVRAM, you can change any
setting just for the current session, as in the following example.
The NVRAM configuration remains intact.
A TX7
<Enter>
But if you want the new setting to be a default, write it to
NVRAM at the same time, as in the following example. X7 is
substituted for the X4 setting stored earlier.
AT X7 &W <Enter>
LOADING THE FACTORY DEFAULTS (&F)
If DIP switch 10 is DOWN, the factory settings are loaded at
power-on instead of the NVRAM defaults. Factory settings for
the options that are stored in NVRAM are in Appendix B.
If the NVRAM defaults are loaded at power-on (DIP switch 10
OFF) and you want to load the factory defaults instead, use the
following command:
AT&F <Enter>
If NVRAM defaults are loaded, but you want to view a screen
listing of factory defaults, first load them (&F), to make them the
current settings. Then include the 14 inquiry option to display a
listing of the newly current settings, as in the following example.
AT&F 14 <Enter>
