2.3 Hardware Installation  
Installation of this modem requires opening and  
manipulatingyourPC.Exercisecautionatalltimeswhen  
working with AC powered and static-sensitive equip-  
ment. Turn off and unplug your PC before installation.  
Dischargeanystaticelectricityfromyourbodybytouch-  
inganygroundedmetalsurfaceofthePCsystem,such  
as its power supply cover.  
1. Turn off and unplug your computer from the AC  
outlet.  
2. Remove your computer's cover (refer to your  
computer's owner's manual).  
3. Selectanyavailable32-bitPCIcardslotand remove  
the slot cover (refer to Figure 2-3).  
Figure 2-3 PCI Expansion Slots  
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.  
8. Optionally, connect your telephone to the modem's  
PHONE connector, a microphone to the MIC con-  
nector and a speaker to the SPK connector.  
9. Turn your computer on. Your modem is now in-  
stalled.

2.6 Testing Your Modem After Installation  
Inordertotestyourmodemyoushouldbefamiliar  
withyourcommunicationsoftware.Loadandsetupyour  
communicationsoftwareandenterintoterminalmode.”  
Make sure that the COM Port and IRQ settings of the  
modem match the software. Type AT on your terminal  
screenandpressENTER.YoumayseeAT”,AATTor  
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

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

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
