&Z Save Addresses (Dial Directory)
Allows the user to save commonly used IP addresses in a nonvolatile memory location <n>, where
<n> can be from 0 to 9. These addresses can be used as dial strings, ping targets, or to define friends
(see Friends Only operation under TCP and UDP). A port number can also be included with the
address. A saved dial string can be invoked with the ATD command modifier Sn, or as a ping target
with an AT*PSn.
Format:
AT&Z=string Save string in location 0
AT&Zn=string Save string in location <n>
AT&Z? Display saved strings
Result codes:
OK Valid argument
ERROR Invalid argument
Table F-3. Commands beginning with Backslash (\)
\F Set Data Forwarding Operation
Determines whether the data forwarding characters specified in S-Registers 51 and 52 are included in
the packet transmitted to the remote data service. For the data forwarding characters to be recognized,
manual transmit mode (\M command) must be enabled.
If only a single data forwarding character is required, set S-Registers 51 and 52 to the same value and
select AT\FO or AT\F3 as appropriate. Refer to Chapter 4, Broadcast and Multicast Operations, Data
forwarding, for more information.
Format:
AT\F0
Data forwarding characters are excluded from the packet (not transmitted)
AT\F1 Data forwarding character specified by S51 is included, but S52 is excluded
AT\F2 Data forwarding character specified by S52 is included, but S51 is excluded
AT\F3 The data forwarding characters in both S51 and S52 are included in packets sent
to the remote data service (default)
Result codes:
OK Valid argument
ERROR Invalid argument
\J Restrict Channel Selection
Enables the modem’s choice of cellular channels to be restricted based on certain CDPD Network
parameters. Each active CDPD channel has an associated SPNI and LSAI (CDPD 1.0), or an SPI,
SPNI, and WASI (CDPD 1.1). The user can require that all, some, or none of these parameters match
similar parameters stored in the DART. Doing so limits the channels and/or the geography available for
modem use. Refer to Channel acquisition restrictions, p. 8-20, for more information.
The SPNI, LSAI, SPI, and WASI are entered and displayed using the AT commands ^H, ^I, and ^L.
\J settings are not reset by ATZ, AT-R, &F or by power cycling the modem.
