4-8 Issue 2 November 1996
The green LED is
flashing, and the red
LED is on, but the
8400B Plus Data
Module does not
automatically
answer the
incoming call.
The automatic
answer option is
not enabled.
From the command mode, type
ATS0=1
to turn on the automatic answer
feature. Set the value following the
equal sign (
1 in the example) to the
ring number on which you want the
8400B Plus Data Module to answer an
incoming call. The automatic answer
feature is turned off by setting this
value to
0.
The automatic
answer option is
enabled, but the
terminal device is
not ready.
If the local terminal is a PC, configure
the communications software to turn on
the DTR lead, or set the 8400B Plus
Data Module to ignore the DTR lead by
typing
AT&D0
Transmitted and/or
received data
contains errors.
Speed settings of
the terminal device
and the 8400B Plus
Data Module are
not the same.
Change terminal device speed to agree
with the speed that was indicated in the
CONNECT
nnnn message.
The local terminal
device and the
far-end device are
configured for
different parity
settings.
Change the parity setting of the local
terminal device to match that of the
far-end device.
Far-end data errors
occur only during file
transfer with PC
communications
package.
PC does not
support hardware
flow control.
Disconnect the call, change the
Disable Data Metering Feature option
to Yes, reestablish the call, and try the
file transfer again.
