Store Phone Numbers
&Z
n=s
This command stores up to ten numbers, where
n is the position
0
−
9 in nonvolatile memory, and
s is the phone number string.
The number-string may be up to 40 characters long, including
any Dial command options.
AT &Z2=555-6789
Do not include modem settings in the &Z
n string. If the call
requires a special setting, insert it in the command string before
the DS
n command. In the following example, &M0 (no error
control) is inserted before the Dial command:
AT&M0 DS2
NOTE: The &Zn=s command functions differently when Dial
Security is enabled. See Appendix D for more information.
&Z

Display the phone number stored in NVRAM at position

(
n = 0
−

Redialing
A/
Re-execute the last issued command. A/ doesn't take the AT
prefix or a Carriage Return, and can be used to redial.
A/
Automated Redialing (>, A>)
While > and A> can be used to continuously repeat any
command, they are designed for automated redialing.
Enter Repeat Mode
>
If you know the modem you are calling is frequently busy,
include the Repeat command in the Dial string, as follows:
AT > DT 1234567
AT DT 1234567 >
The modem enters Repeat mode, dials the number, waits 60
seconds for a carrier (default), and hangs up. Then after a two-
second pause, it redials.
