2.4 Hardware Configuration (Plug and Play)
YourmodemisconfiguredusingthePlugandPlay
(PnP) capabilities of your computer. Plug and Play is a
set of specifications that define the ability for the com-
puter hardware and operating system to automatically
configureallcompliantdevicesthatareinstalled,reliev-
ing the user of the need to determine which addresses
andinterruptstouseforeachdevice.ConsultyourPC's
owner's manual to determine if it is PnP Revision 1.0a
compliant.YoumostlikelyhaveaPlugandPlayRevision
1.0a compliant system if it was purchased after June
1994 or if the BIOS is dated after June 1994.
Proceedtooneofthefollowingsections,depending
onyoursystem'sconfiguration:
• Section 2.4.1 if you are running Windows
95 (with or without a Plug and Play PC)
• Section 2.4.2 if you are running Windows
3.1x or DOS on a PnP-compliant PC.
• Section 2.4.3 if you are running Windows
3.1x on a non-PnP PC.
2.4.1 ConfiguringinWindows95
When Windows 95 starts for the first time after
cardinstallation,itdetectsthemodemanddisplaysthe
NewHardwareFounddialogbox.
Under New Hardware Found, when asked to
“Select which driver you want to install for your new
hardware,” click on “Driver from disk provided by hard-
waremanufacturer.”Click“OK.”

The Install From Disk dialog box now instructs
youto“Insertthemanufacturer'sinstallationdiskintothe
drive selected, and then click OK.” Insert the modem's
Utility diskette into the disk drive and type A:\ (or B:\ if
inserted in drive B) in the “Copy manufacturer's files
from:” box. Click “OK.”
Windows95mayrequestitsowninstallationdisks

When all necessary files are copied, the modem is
configured. Windows95willassignthemodemaCOM
port and IRQ line.
Windows95communicationpackageswillrecog-
nizethemodembyname. Windows3.1xcommunication
packages running under Windows 95 need to access
the modem via the COM port designation given to the
modem. This can be found by running Control Panel
(Start|Settings|Control Panel), double-clicking Mo-
dems,selectingthemodemandclickingon“Properties”
under the General tab. Note which COM port is being
used by the modem. Proceed to Section 2.5, Software
Installation/Configuration.
2.4.2 ConfiguringinaPlugandPlaySystemwithout
Windows95
When this modem is installed in a Plug and Play
system without Windows 95, the computer's BIOS will
assign a COM port and IRQ line to the modem.

2.7 Testing Your Modem After Installation
Inordertotestyourmodemyoushouldbefamiliar
withyourcommunicationsoftware.Loadandsetupyour
communicationsoftwareandenterinto“terminalmode.”
Make sure that the COM Port and IRQ settings of the
modem match the software. Type AT on your terminal
screenandpressENTER.Youmaysee“AT”,“AATT”or
nothing on the screen. In any case, the modem should
respondwithanOKor0.Ifitdoesnot,eitherthemodem
maynothavebeeninstalledproperlyorthesoftwarehas
notbeenproperlyconfigured.ReviewSections2.2-2.5
and be certain that the modem and the software have
beenproperlyinstalled.Ifrequired,refertoSection6for
additional troubleshootinginformation.
2.8 Using Your Modem
The communication software included with your
modem product provides a user friendly interface to
accessthefax,voiceanddatafunctionsofyourmodem.
This software should be sufficient for all of your
communicationneeds.Theremaybetimeswhenyou
need to access the modem manually via modem com-
mands.ReadSection3forasummarydescriptionofthe
modem command set before manually accessing the
modem.Youmaywanttoreadthesoftwaremanualfirst,
however, as the software may already provide a user
friendlymethodofaccessingthefunctionsyouneed(i.e.
dialingoransweringcalls).
2.9 Where To Go From Here
Youshouldfamiliarizeyourselfwiththefunctions
availablefromtheincludedsoftwarebyreadingitsmanual.
You will be accessing most, if not all, of the modem's
functionsfromthis software.Youmayalsouseanyother
commerciallyavailable communicationsoftwarewiththe
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 - Trouble-
shootingtofindanswerstocommonlyaskedquestions
andproblems.

Section Four - S Registers
Your modem has 41 registers, designated S0
through S95. Table 4-1 shows the registers, their func-
tions,andtheirdefaultvalues.Someregisterscanhave
their values changed by commands. If you use a com-
mandtochangearegistervalue,thecommandremains
in effect until you turn off or reset your modem. Your
modem then reverts to the operating characteristics
specifiedinitsnon-volatilememory. RefertoSection3
for information on how to use the AT commands to
manipulatetheSregisters.
