Recovering At Commands - Paradyne 3825Plus Quick Reference Manual

To change a factory template, perform the following steps.
Procedure
1. Use the AT&F&W command to load the appropriate factory configuration to the
appropriate storage area. Enter the following:
TYPE: AT &F f &W n (in all uppercase or all lowercase)
Where: f is one of the following Factory configurations:
0 for Async Dial
3 for UNIX Dial
5 for Cellular (Mobile)
6 for Cellular (PSTN)
(&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
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 storage areas.
2. Press Enter.
The selected factory configuration is saved.
To establish a connection with a remote modem, use the D (Dial) command.

Recovering AT Commands

AT commands are issued from asynchronous terminals and personal computers.
Certain dialing methods, such as V.25bis and synchronous operation, disable the use
of AT commands. The 3825 Plus is capable of normal operation, but configuration
options cannot be changed unless AT command recovery is performed.
The AT Recovery command (AT***) places the modem into a temporary state that
restores AT commands. When in this state, the modem's previous settings are retained
except for the following configuration options:
The DTE Dialer Type configuration option (&M and &Q) is set to AT
The Async/Sync Mode configuration option (&M and &Q) is set to Async
The DSR Control configuration option (&S) is set to Forced On
The LSD Control configuration option (&C) is set to Forced On
