4. Carefully slide the PCI internal modem into the slot
you have chosen, applying even pressure until the
modem is completely seated in the slot.
5. Fasten the retaining bracket with the screw from
the slot cover. Make sure the modem is properly
aligned. Store the slot cover for future use.
6. Replace the computer cover and plug in your com-
puter.
7. Connectthetelephonecablefromthemodem'sLINE
connector to the telephone wall jack.

2.6 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 all cases, the modem should
respondwithanOKor0.Ifitdoesnot,eitherthemodem
has not been installed properly or the software has not
beenproperlyconfigured.ReviewSections2.2-2.5 and
be certain that the modem and the software have been
properly installed. If required, refer to Section 6 for
additional troubleshootinginformation.
2.7 UsingYourModem
The software included with your modem product

2.8 Where To Go From Here
Youshouldfamiliarizeyourselfwiththefunctions
available from the included software by reading its
manual. You will be accessing most, if not all, of the
modem'sfunctionsfromthis software.Youmayalsouse
anyothercommerciallyavailable communicationsoft-

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
questionsandproblems.

Section Four - S Registers
Your modem has 24 registers, designated S0
through S33. 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.RefertoSection3for

Section Six - Troubleshooting
Thissectiondescribessomeofthecommonprob-
lemsyoumayencounterwhileusingyourmodem.Ifyou
cannotresolveyourdifficultyafterreadingthischapter,
contact your dealer or vendor for assistance.
Modem does not respond to commands.
1. Make sure the modem is not configured with a
conflictingCOMportandIRQsetting(seeSections
2.2-2.5). As an example, your modem can not be
configuredasCOM1ifanotherdeviceinyoursystem
isalsoconfiguredasCOM1.
2. Makesurethecommunicationsoftwareisconfigured
to“talk”tothemodemonthecorrectCOMportandIRQ
setting (same COM port and IRQ setting as the
modem).Yourcommunicationsoftwaremustknow
whichaddressyourmodemisusinginthesystemin
ordertopassdatatoit.Similarly,IRQsettingsmustbe
set correctly to receive data from the modem.
3. Make sure that your modem is initialized correctly.
Yourmodemmayhavebeeninitializedtonotdisplay
responses. You may factory-reset the modem by
issuing AT&F and pressing ENTER. The factory
defaultallowsthemodemtodisplayresponsesafter
acommandhasbeenexecuted.
4. Make sure the baud rate setting in your software is
setto115200, 57600, 38400, 19200, 14400, 9600,
2400, 1200, or 300 bps. An incorrect baud rate
preventsthemodemfromoperatingproperly.
15
Modem does not dial.
1. Make sure the modem is connected to a working
phoneline.Replacethemodemwithaworkingphone
to ensure that the phone line is working.
Modem dials but does not connect.
1. Make sure the IRQ setting is identical on both the
modem AND the software. Modem and software
mustbeconfiguredidentically.
2. Makesurethephonelineisworkingproperly.Replace
themodemwitharegularphoneanddialthenumber.
If the line sounds noisy, you may have difficulty
connectingtotheremotedevice.
Modem makes a connection but no data
appears on your screen.
1. The remote system may be waiting to receive your
databeforeitbegins.TrypressingtheENTERkeya
few times.
2. Makesurethecorrectdataformat(databits,stopbits,
andparitybits)andflowcontrol(RTS/CTS)arebeing
used.
3. Make sure the correct terminal emulation mode is
beingused.
High pitch tone is heard whenever you answer
thephone.
1. MakesureAuto-Answeristurnedoff. Yourmodem
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. MakesuretheDTEspeedisthesameasthemodem
