&W0 Stores all current AT command and S-register values in nonvolatile random access
memory (NVRAM) and configures TA to read custom settings in NVRAM when modem
turned on or when reset with
Z
command. (
&F
reset command continues to read factory
default settings in ROM.)
&W1
Erases your custom settings in NVRAM the next time the TA is turned off or reset, causing
the TA to read the factory default settings in ROM whenever it is turned on or reset.
