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®  
95), follow the instructions included with the operating  
system to configure Plug and Play cards.  
OnAcerpre-configuredsystemswiththismodemand  
Windows 95 software, this modem has been set to:  
'MODEM'  
Sierra 14.4 Data Fax Voice SQ3230

COM 1, IRQ 4  
'MODEMVOICE'  
Sierra 3230 (Voice)  
DMA 3, IRQ 10  
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.SelectaGenericClass  
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.YoumayseeAATTor  
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.  
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 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 Four - S Registers  
Your modem has 39 registers, designated S0 through  
S27, S36-S38, S46, S48-S50, S63, S82, S86, andS98. Table  
4-1 shows the registers, their functions, and their default  
values. Some registers can have their values changed by  
commands. Ifyouuseacommandtochangearegistervalue,

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  
“talktothemodemonthecorrectCOMportandIRQsetting  
(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.
