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.

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.

3.3 Basic AT Commands

Section Four - S Registers

Your modem has 39 registers, designated S0 through
S27, S36-S38, S46, S48-S50, S63, S82, S86, and S98. Table
4-1 shows the registers, their functions, and their default
values. Some registers can have their values changed by
commands. If you use a command to change a register value,
the command remains in effect until you turn off or reset your
modem. Your modem then reverts to the operating character­istics specified in its non-volatile memory. Refer to Section
3 for information on how to use the AT commands to
manipulate the S registers.

Section Six - Troubleshooting

This section describes some of the common problems
you may encounter while using your modem. If you can not
resolve your difficulty after reading this chapter, contact your
dealer or vendor for assistance.

Modem does not respond to commands.

1. Make sure the communication software is configured to

“talk” to the modem on the correct COM port and IRQ setting
(same COM port and IRQ setting as the modem). Your
communication software must know which address your
modem is using in the system in order to pass data to it.
Similarly, IRQ settings must be set correctly to receive data
from the modem.

2. Make sure that your modem is initialized correctly. Your

modem may have been initialized to not display responses.
You may factory-reset the modem by issuing AT&F and
press ENTER. The factory default allows the modem to
display responses after a command has been executed.

3. Make sure the baud rate setting in your software is set to

57600, 38400, 19200, 14400, 9600, 2400, 1200, or 300 bps.
An incorrect baud rate prevents the modem from operating
properly.

4. Make sure that the modem is not conflicting with another

COM port or IRQ in a non-PnP system.

Modem does not dial.

14

1. Make sure the modem is connected to a working phone line.

Replace the modem with a working phone to ensure that the
phone line is working.

2. Make sure the phone line is connected to the jack marked

“LINE.” Incorrect connection prevents the modem from
operating properly. Refer to Section 2.2 for modem connec­tion instructions.

Modem dials but does not connect.

1. Make sure the IRQ setting is identical on both the modem and

the software in a non-Pnp system. Modem and software must
be configured identically.

2. Make sure the phone line is working properly. Replace the

modem with a regular phone and dial the number. If the line
sounds noisy, you may have difficulty connecting to the
remote device.

Modem makes a connection but no data appears
on your screen.

1. The remote system may be waiting to receive your data before

it begins. Try pressing the ENTER key a few times.

2. Make sure the correct data format (data bits, stop bits, and

parity bits) and flow control (RTS/CTS) method are being
used.

3. Make sure the correct terminal emulation mode is being used

(see communication software manual).

4. Make sure the modem is not sharing an IRQ or COM port with

another device in a non-PnP system.

High pitch tone is heard whenever you answer the
phone.

1. Make sure Auto-Answer is turned off. Your modem is factory

configured to NOT auto-answer. Issue AT&F to factory reset
your modem.

Modem experiences errors while communicating
with a remote modem.

1. Make sure the DTE speed is the same as the modem connec-

tion speed when in Direct Mode (\N1 command in effect).

2. Make sure the remote system and your modem use the same

communication parameters (i.e., baud rate, data bit length,
parity, and stop bit).

3. Make sure RTS/CTS hardware flow control is enabled and

XON/XOFF software flow control is disabled in the commu­nication software.

4. Make sure the data speed is not faster than your computer's

15

capability. Most IBM compatibles are capable of 19,200 bps
under DOS and Windows. Operating at higher speeds under
Windows requires a faster CPU (386/486 or better).

Modem experiences bursts of errors or suddenly
disconnects while communicating with a remote
modem.

1. Make sure Call Waiting is turned off.

2. Make sure the phone line does not exhibit excess noise.

Modem exhibits poor voice record or playback.

1. Make sure the correct modem type is selected in the Voice/

FAX software. Use “Sierra” or similar selection. Do not
select “Rockwell or Rockwell ICS” configuration.

9.3 DOC Compliance Information

NOTICE: The Canadian Department of Communications label

identifies certified equipment. This certification means that the
equipment meets certain telecommunications network protective,
operational and safety requirements. The Department does not
guarantee the equipment will operate to the user’s satisfaction.

Before installing this equipment, users ensure that it is permissible
to be connected to the facilities of the local telecommunications
company. The equipment must also be installed using an accept­able method of connection. The customer should be aware that
compliance with the above conditions may not prevent degrada­tion of service in some situations.

Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications com­pany cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical
ground connections of the power utility, telephone lines and
internal metallic water pipe system, if present, are connected
together. This precaution may be particularly important in rural
