Configuration Storage And Recall Commands; Modem Response (Result Code) Commands - Multitech MT5634HD16 User Manual

Configuration Storage and Recall Commands

The MT5634HD8/16 stores parameters in two places. It stores factory default parameters in read-only
memory (ROM), and customized parameters in nonvolatile random access memory (NVRAM). You can-
not 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.
&Wn Store Configuration
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 it.
&W0 (or &W) stores all current AT command and S-register values in 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 ROM.
&Fn Load Default Configuration
n = 0
Default: &F0
MT5634HD8/16 modems store factory default AT command settings and S-register values in read-only
memory (ROM); they store your custom AT command and S-register values in nonvolatile random access
memory (NVRAM).
The &F0 (or &F) command resets the modem to the factory default values stored in ROM.
Zn Reset Modem
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.
&Yn Select Stored Configuration for Hard Reset
n = 0
Default: 0
This command is included for compatibility with applications that issue the &Y0 command. Modem
functions are not changed.
&Y0 selects the profile stored at location 0 on power-up.

Modem Response (Result Code) Commands

The MT5634HD8/16's modems can give responses to commands. The most common one is OK , but the
modems can also alert you or your software to dial tones, busy signals, connection speeds, and whether the
