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).
