On initial power-up, the modem is in Command
mode. To verify that the modem is connected and
functioning properly, enter the following:
TYPE: AT
PRESS: Return (Enter)
The screen displays OK.
If the modem does not return OK, refer to Appendix C,
Troubleshooting.
NOTE
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 14, 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 14, AT Command Set and
S-Registers, for more on AT commands.
