2.3 Plug and Play

Your modem supports Plug and Play (PnP) and can
easily be configured using any Plug and Play compliant PC.
Your PC is PnP compliant if you have: 1) an operating system
that supports Plug and Play, and 2) PnP BIOS/chipset.

In a PnP compliant operating system (e.g. Windows

95), follow the instructions included with the operating
system to configure Plug and Play cards.

On Acer pre-configured systems with this modem and
Windows 95 software, this modem has been set to:

'MODEM'

Sierra 14.4 Data Fax Voice SQ3230

®

2

COM 1, IRQ 4

'MODEM VOICE'

Sierra 3230 (Voice)
DMA 3, IRQ 10

2.4 Software Installation/Configuration

You are now ready to install and configure the commu­nication software. Refer to your software manual for instal­lation procedures. Your software must be configured to
communicate with the modem on the same COM port and
IRQ line used by the modem.

We suggest the following communication parameters
when you first use your data communication software.
Consult the software manual for information on using these
and other parameters/features.

38,400 bps; 8 data bits; no parity; 1 stop bit; RTS/
CTS flow control set to “on;” initialization string:
AT&F

The commands used by the modem are compatible
with the command set used by the “Hayes V-series Ultra
Smartmodem 14400” modems, select this modem type in
your data communications software. Select a “Generic Class
2” modem type in your FAX software and select a “Sierra”
modem type in your voice software.

2.5 Using Fax, Voice, and Speakerphone

Capabilities of the Modem

Your modem has built-in advanced FAX, Voice, and
Full Duplex Speakerphone functions. These functions are
accessed through software. Please consult your FAX/Voice/
Speakerphone software manual about procedures on using
these functions. Note that the modem's FAX/Voice/Speaker­phone commands are used by the software to implement
these functions and are not designed to be used as stand­alone AT commands.

Voice functions include recording and playback of
voice prompts (files). You may record or playback voice with
your modem by attaching a telephone to the RJ-11 jack
marked "PHONE" or by attaching a microphone to the MIC
jack located on the back of the modem bracket. Then follow
instructions in the FAX/Voice/Speakerphone software on
recording and playback of voice prompts.

2.6 Testing Your Modem After Installation

In order to test your modem you should be familiar
with your communication software. Load and set up your
communication software and enter into “terminal mode.”
Make sure that the COM Port and IRQ settings of the
software modem match the modem. Type AT on your
terminal screen and press ENTER. You may see “AATT” or
nothing on the screen. In either case, the modem should
respond with an OK or 0. If it does not, please refer to Section
6 for troubleshooting information.

2.7 Using Your Modem

The communication software included with your mo­dem product provides a user friendly interface to access the
fax, voice, and data functions of your modem. This software
should be sufficient for all of your communication needs.
There may be times when you need to access the modem
manually via modem commands. Read Section 3 for a
summary description of the modem command set before
manually accessing the modem. You may want to read the
software manual first, however, as the software may already
provide a user friendly method of accessing the functions you
need (i.e. dialing or answering calls).

2.8 Where To Go From Here

You should familiarize yourself with the functions
available from the included software by reading its manual.
You will be accessing most, if not all, of the modem's
functions from this software. You may also use any other
commercially available communication software with the
modem. Read Section 3 only if you are interested in accessing
the modem manually, and not through the included software.
Section 4 and 5 contain reference material, and can be
skipped. If you have difficulties getting your modem to work,
read Section 6, Troubleshooting, to find answers to com­monly asked questions and problems.

Section Three - AT Command Set

3.1 Executing Commands

Commands are accepted by the modem while it is in
Command Mode. Your modem is automatically in Com-

4

mand Mode until you dial a number and establish a connec­tion. Commands may be sent to your modem from a PC
running communication software or any other terminal de­vices.

Your modem is capable of data communication at rates
of: 300, 1200, 2400, 4800, 9600, 14400, 19200, 38400, and
57600 bps. Make sure your COM port baud rate setting in
your communications software is set to one of the above
speeds.

3.2 Command Structure

All commands sent to the modem must begin with AT
and end with ENTER. All commands may be typed in either
upper or lower case, but not mixed. To make the command
line more readable, spaces may be inserted between com­mands. If you omit a parameter from a command that
requires one, it is just like specifying a parameter of 0.
Example:

ATH [ENTER]

This command causes your modem to hang up.
