At Command Recovery - Paradyne 2001 User Manual

AT Command Recovery

The following describes AT Command Recovery which returns
your DataPort 2001 from "Dumb" mode. While in Dumb mode,
the DataPort 2001 ignores all AT commands. This mode is only
applicable to DataPort 2001s used in synchronous applications.
P: Your DataPort 2001 enters Dumb mode.
S: Synchronous dialing disables the use of AT commands and
places the DataPort 2001 into a state known as Dumb
mode. The DataPort 2001 operates fine in this mode, but
cannot be returned to Asynchronous mode where AT
commands are used.
The following procedures, known as AT Command
Recovery, restore AT commands. Review these procedures
before performing the recovery.
1. Turn the DataPort 2001 Off.
2. Turn the DataPort 2001 ON and immediately hold down
the A key on your computer keyboard.
After the power-up self-test, in which all front panel lights
turn ON, several A characters appear on your monitor. Hold
down the key long enough for at least three consecutive A 's
to appear on your monitor.
3. Next, type T*** and press Enter. This must occur within
10 seconds of the previous entry.
(Make sure that you are consistent using uppercase or
lowercase characters, for example, at*** or AT***.)
OK appears on your monitor. The DataPort 2001 is now in
AT Command Recovery mode and remains in this state until
a Save (AT&W) or power reset occurs. If you do not issue
AT&W, the DataPort 2001 returns to Dumb mode when
power is lost.
