Data Operation
Issue 2 November 1996
3-13
Automatic Answering
The 8400B Plus Data Module can be set up to answer incoming data calls
automatically. To initialize this option, type the command line:
ATS0=
nnn
where nnn is a decimal number in the range of 1 through 255, representing the
number of rings to wait before answering. If nnn is 0 (the factory-default setting),
the automatic answer feature is turned off.
Remote Site Use
The 8400B Plus Data Module can be used at a remote site as a dedicated
service device to answer incoming data calls, send data to a remote end device,
and then hang up. For example, you may wish to provide access to a printer
from a remote site.
The following is a typical command line you might use for setting up this
operation (spaces are used here for readability, but are not required):
AT &F &C1 &D2 E0 Q1 S0=1 &W0 &Y0
Following the AT prefix, the commands in the example produce the following
results:
■ &F resets the options to the factory defaults.
■ &C1 sets the Data Carrier Detect (DCD) circuit of the 8400B Plus Data
Module to operate according to the EIA standard.
■ &D2 sets the 8400B Plus Data Module to go on hook when an on-to-off
transition is detected on the Data Terminal Ready (DTR) input,
disconnecting the call.
■ E0 turns off the echo.
