MT3334HD8 User Guide

The &W0 (or &W) command stores all current AT command and S-register values into nonvolatile random access memory (NVRAM) and configures the modem so that it reads your custom settings in NVRAM when the modem is turned on or when it is reset with the Z command. (The &F reset command will continue to read the factory default settings in read-only memory [ROM] unless you also store the &F9 command. See Chapter 3.) For convenience, you can include the &W command in the same command string that sets the new values in active memory, as in the following example:

AT&E2$SP1#L3$R0$MB19200$SB115200$EB1S0=10&W0<CR>

The &W1 command erases your custom settings in NVRAM the next time the modem is turned off or reset, causing the modem to read the factory default settings in ROM when it is subsequently turned on or reset.

For further information on how the &W command interacts with the reset commands, see Table 2 on page 21.

Before you use the &W command, check the modem’s current operating parameters by using the L5, L6, and L7 commands.
