2.3 Plug and Play
Your modem supports Plug and Play (PnP) and can
easily be configured using any Plug and Play compliant PC.
YourPCisPnPcompliantifyouhave:1)anoperatingsystem
that supports Plug and Play, and 2) PnP BIOS/chipset.
InaPnPcompliantoperatingsystem(e.g. Windows®

2.4 Software Installation/Configuration
Youarenowreadytoinstallandconfigurethecommu-
nication software. Refer to your software manual for instal-
lation 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
yourdatacommunicationssoftware.Selecta“GenericClass
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
accessedthroughsoftware. PleaseconsultyourFAX/Voice/
Speakerphone software manual about procedures on using
thesefunctions.Notethatthemodem'sFAX/Voice/Speaker-
phone commands are used by the software to implement
these functions and are not designed to be used as stand-
alone AT commands.
Voice functions include recording and playback of
voiceprompts(files).Youmay recordorplaybackvoicewith
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
terminalscreenandpressENTER.Youmaysee“AATT”or
nothing on the screen. In either case, the modem should
respondwithanOKor0.Ifitdoesnot,pleaserefertoSection
6 for troubleshooting information.
2.7 Using Your Modem
The communication software included with your mo-
dem product provides a user friendly interface to access the
fax, voice, anddatafunctionsofyourmodem. Thissoftware
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
provideauserfriendlymethodofaccessingthefunctionsyou
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.ReadSection3onlyifyouareinterestedinaccessing
themodemmanually,andnotthroughtheincludedsoftware.
Section 4 and 5 contain reference material, and can be
skipped.Ifyouhavedifficultiesgettingyourmodemtowork,
read Section 6, Troubleshooting, to find answers to com-
monly asked questions and problems.

mand Mode until you dial a number and establish a connec-
tion. Commands may be sent to your modem from a PC
running communication software or any other terminal de-
vices.
Yourmodemiscapableofdatacommunicationatrates
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 withAT
andendwithENTER. Allcommandsmaybetypedineither
upper or lower case, but not mixed. To make the command
line more readable, spaces may be inserted between com-
mands. 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.

Section Six - Troubleshooting
This section describes some of the common problems
you may encounter while using your modem. If you can not
resolveyourdifficultyafterreadingthischapter,contactyour
dealer or vendor for assistance.
Modem does not respond to commands.
1. Make sure the communication software is configured to
“talk”tothemodemonthecorrectCOMportandIRQsetting
(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
fromthemodem.
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
displayresponsesafteracommandhasbeenexecuted.
3. Make sure the baud rate setting in your software is set to
57600, 38400, 19200, 14400, 9600, 2400, 1200, or300bps.
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.
