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 4, AT Commands and S-Registers).
" Procedure
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 SDCP as described earlier in
Selecting Configurations Using the SDCP. &F5
and &F6 are available only if ETC is installed.)
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 4, AT Commands and
S-Registers, for more on AT commands.
NOTE
When configuring your modem,
keep a record of its configuration
options as a future reference in
case the modem must be
replaced.
To establish a connection with a remote modem, use
the D (Dial) command. Refer to Chapter 4, AT Commands
and S-Registers, for more information.
