26 Intel Confidential Programmer’s Guide
previously-saved telephone numbers can be read from the modem using the view command,
AT&V n. The AT&Zn =x command stores one of four telephone numbers in the NVRAM. To dial
these telephone numbers, use the ATDS= n command.
If the active profile is not stored in one of the two user profiles after setting up the modem, then the
current settings are lost when the commands ATZ o r AT&F are issued or when the modem is
powered down.
Examples:
ATZ Resets and then configures the modem to
NVRAM user profile 0.
AT&F S0=1 &W1 &F configures the modem for factory defaults.
&Y1
S0=1 configures the modem to answer after
one ring.
&W1 saves the active configuration to user
profile 1.
&Y1 configures the modem to use NVRAM user
profile 1 as the power-up defaults.
AT&Z2 = 9, Stores a telephone number into the NVRAM as
phone number 2, which can be
(408)444-5555 re-dialed later using ATDS =2.
3.4 Modem Identification Commands [In, +FMI?, +FMR?, +FMM?, +GMI?, +GMM?, +GMR?, +FMFR?, +FMDL?, +FREV?]
The modem provides product identification AT commands that help determine the modem’s
manufacturer, model number, and product revision. To provide flexibility with older software
application programs, the modem supports several commands that can be used to request a single
item of identification (such as a modem model number). Table 3 -1 lists the commands used to
obtain product information (all identification commands are usable in data, fax, or voice mode).
