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
icommand. (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
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.
Command: $MBn
Function: V.110 Network Rate*
Values: n = 600, 1200, 2400, 4800, 9600, 19200, 38400
Default: $MB38400
Description: If S77=1, then the network rate of the V.110 connection will match that of $MB (S76).
If a V.110 call is received and S77=1, then the incoming V.110 network rate must match
$MB (S76) or the connection will fail. If S77=2 and a V.110 call is originated, then the
network rate will match that of $MB (S76). If S77=2 and a V.110 call is received, then the
setting of $MB (S76) will have no effect on the network rate of that call (see S77 for a
