When the modem is turned on or reset by command ATZ, the ACA
is first loaded with the FDP, and then is overwritten by the major
SCP. The commands you issue to the modem actually change the
contents of the ACA. However, once the modem is turned off, all
the settings in the ACA vanish.
To save the current ACA configuration to a SCP for further use,
issue command &W followed with the number of the SCP. For
example, issue &W1 saves the current configuration to SCP1.
The next time you want to use the same configuration, just issue
AT&1 to load the ACA with the SCP1 previously saved.
Issuing &V0 command displays the current configuration profile,
the stored configuration profiles, as well as the current speed, data
format, parity and protocol.
2.14 Stored Telephone Numbers (STN)
The STN are the digits retained in the modem NVRAM and used
for speed dialing. You may use it to save frequently used
telephone numbers, passwords, or credit card numbers.
To store a telephone number as an STN, use &Z followed by the
STN number, the"=" sign, and the telephone number. For example,
&Z2=886-2-2782-0305 stores 886-2-2782-0305 as STN2.
Note that only digits can be stored in STN. Other characters or
symbols are discarded.
To view the STN, issue command &V1. To dial an STN, issue S=n,
where n denotes the nth STN. For the example above, issuing
ATDS=2 instructs the modem to dial 886-2-2782-0305.
