If you have already changed the factory preset configuration you may have lost AT command control. To regain AT command control, select, via the DCP, the Async Dial factory preset configuration as described earlier in Using the Diagnostic Control Panel (DCP).

To change a factory template using AT commands, perform the following steps (for more information on changing factory templates using AT commands, refer to Chapter 13, AT Command Set and S-Registers).

1.Use the AT&F&W command to load the appropriate factory configuration to the appropriate storage area. Enter the following:

TYPE: AT&Fy&Wn

Where: y is one of the following Factory configurations:

0 for Async Dial

1 for Sync Dial

2 for Sync Leased (Answer)

3 for UNIX Dial

4 for Sync Leased (Originate)

5 for Cellular (Mobile)

6 for Cellular (PSTN)

(NOTE: &F1, &F2, and &F4 remove AT command control. The only way to return to AT command control is through the DCP as described earlier in Using the Diagnostic Control Panel (DCP).)

and

Where: n is one of the following storage areas: 0 for Active (Saved)

1 for Customer 1

2 for Customer 2

(NOTE: These three configuration areas are nonvolatile memory locations. Active (Saved) contains the most recently saved changes to any configuration options. In the event of power loss, the modem retrieves these configuration options. Customer 1 and Customer 2 are user-defined configuration areas.)

PRESS: Return (Enter)

2. The selected factory configuration is saved.

The &V (View) command can be used to display the configuration options in effect. The output of the &V command can be saved to a file and printed (using your communications software), providing both a record of your configuration and a worksheet for configuration enhancements. Refer to Chapter 13, AT Commands and S-Registers, for more on AT commands.
