MTA128ST-USB
Command: &Wn
Function:
Store Active Profile
Values: n = 0 or 1
Default: &W1 (Use factory default profile)
Description: Stores your active profile, or configuration, in memory, so you won't lose
custom settings when you turn off the TA or reset it.
&W0
Stores all current AT command and S-register values in nonvolatile
random access memory (NVRAM) and configures the TA so it reads
your custom settings in NVRAM when the TA is turned on or when it
is reset with the Z command. (The &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 factory default settings in
ROM whenever it is turned on or reset.
Command: &Zn=x
Function:
Store Telephone Number
Values: n = 0–9; x = dial string
Default: n/a
Description: The &Z= command lets you store a telephone number in a memory register
for faster dialing. To store a number, type &Z, the register number (0–9)
where you want to store the number, the = character, and the dialing string
that you want stored; then press ENTER. The dialing string can have up to
25 characters. To read a stored number, type AT&Zn? (e.g., AT&Z4?) where
n is the number of the register you want to read. To display a list of all
numbers stored in memory, type ATL and press RETURN:

Command: $Dn
Function:
Persistent DTR Dialing
Values: n = 0, or 1
Default: $D0 (Disabled)
Description: Enables or disables persistent DTR dialing (PDD). PDD causes the terminal
adapter to automatically and continuously redial stored telephone number 0
when the port has no active calls and DTR is high.
$D0
Disables PDD.
$D1 Enables PDD.
