Configuration Storage and Recall Commands
The MT5634HD8 stores parameters{xe "parameters"} in two places. It stores factory
default parameters in read-only memory ({xe "ROM (read-only memory)"}ROM),
and{xe "memory:read-only (ROM)"}{xe "memory:nonvolatile (NVRAM)"} custom-
ized parameters in {xe "NVRAM (nonvolatile random access memory)"}nonvolatile
random access memory (NVRAM){xe "memory:nonvolatile (NVRAM)"}. You cannot
change the default parameters in ROM, but you can change parameters in
temporary memory and then store them in NVRAM as custom settings. You can then
recall the custom settings as if they were factory default settings.
&W n Store Configuration{xe "storing a configuration"}{xe "AT
commands:&W"}{xe "Store Configuration command"}
n = 0
Default: &W0
The &W command stores current AT commands and S-register values in nonvolatile
memory, so you won’t lose your custom settings when you turn off the modem or reset
i t .
&W0 (or &W) stores all current AT command and S-register values in {xe "NVRAM
(nonvolatile random access memory)"}nonvolatile random access memory
(NVRAM){xe "memory:nonvolatile (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 ROM.
&F n Load Default Configuration{xe "AT commands:&F"}{xe "Load Default
Configuration command"}
n = 0
Default: &F0
MT5634HD8 modems store factory default AT command settings and S-register val-
ues in {xe "ROM (read-only memory)"}read-only memory (ROM){xe "memory:read-
only (ROM)"}; they store your custom AT command and S-register values in {xe
"NVRAM (nonvolatile random access memory)"}nonvolatile random access memory
(NVRAM){xe "memory:nonvolatile (NVRAM)"}.
The &F0 (or &F) command resets the modem to the factory default values stored in
ROM.
Z n Reset Modem{ XE "AT commands:Z" }{ XE "Reset Modem command" }
n = 0 or 1
Default: none
The Z command resets the modem to the configuration last saved by the &W
command. The default values come from the customized configuration in NVRAM.
Z1 is the same as Z0, and functions identically.
&Y n Select Stored Configuration for Hard Reset{ XE "AT commands:&Y" }{
XE "Select Stored Configuration for Hard Reset command" }
n = 0
Default: 0
