COURIER HIGH SPEED MODEMS

DEFAULT SETTINGS

USER-PROGRAMMABLE DEFAULTS

You can create your own default configuration and store it in nonvolatile random access memory (NVRAM) using the &W command described in Chapter 4. As long as DIP switch 10 is OFF when you power on the modem, your defaults are loaded into the modem's random access memory (RAM). To view your NVRAM settings at any time, use the ATI5 command.

Tables on the next several pages list the options you can store in NVRAM, including S-Register settings. If DIP switch 10 is ON at power-on, the factory template 0 settings are loaded instead. The modem has four factory setting templates (&F0−F3). By default, the first time the modem is turned on, the modem loads the settings stored in NVRAM, which are the same as the settings in factory template 1 (&F1).

The following command example substitutes several user- defined defaults for factory settings. The modem also stores the rate, word length and parity it detects from the AT command prefix.

AT X1 &B0 &M5 &H0 M3 &W <Enter>

The modem is shipped with DIP switch 10 OFF, so when it is powered on it loads the settings from NVRAM. Until these settings are changed, they are the same as the settings permanently stored in factory settings template 1 (&F1). You can alter any of these settings, create your own power-on defaults, and then save them with the &W command. See Chapter 4.
