5634BIF User’s Manual4CChhaapptteerr 11 IInnssttaalllliinngg tthhee mmooddeemmChapter 1 provides detailed instructions for installing your modem.1.1 Checking your componentsUnpack your components and make sure you have the following items:l The modem.l A modular telephone cable to connect your modem to the telephone line.l This user's manual.l Communication software and manual.When you open your package, make sure all of the above items are included and notdamaged. If you see that any components are damaged, please notify your dealerimmediately.1.2 What else you needTo complete your data communication system, you will need the following items :l Some type of communication software, if not included.l A telephone set and line. (if you do need to use a telephone with your modem)l You also need an available card slot in the personal computer.1.3 Installing the modemThe following instructions explain how to install the modem in a IBM compatible typepersonal computer. If you will be installing the modem into a different computer, refer tothe manual that accompanied your computer or contact your computer dealer forinstructions on installing the modem in your personal computer.1.4 Removing the computer coverTurn off the personal computer's power. No power must be applied to your computer whenyou install the internal modem and computer could be damaged.Make sure you can freely access the back of the personal computer.Unscrew the necessary screws to loosen the computer cover. Then set the screws in asafe place and remove the computer cover.1.5 Setting the modem switchesRead this section if :l You have a serial communication card for another modem.l You will be configuring the internal modem for a communication port other than COM1.If your computer contains a serial or multifunction card, you may have to change theCOM1 address of the modem so that your personal computer can then communicate with
5634BIF User’s Manual5your serial or multifunction I/O card at one COM port and your modem at another.The COM port setting is a "logical" address, and has nothing to do with the slot in whichthe modem(or serial adapter) is installed.To change the default COM port setting from COM1 to another setting :1. Set the switches ( jumpers ) on the modem to specify COM2, COM3, or COM4. Figure1-1 shows the switch locations on the modem. Table 1-1 describes the setting.2. Configure your communication software to the new COM port and IRQ settings.34579101112SHORT15IRQOPENABCD5634BIFFigure 1-1 View of the modemTable 1-1 modem switch (jumper)settingsCOM Port ABCD HexAddress IRQCOM1 ON OFF ON OFF 3F8 to 3FF 4COM2 ON OFF OFF ON 2F8 to 2FF 3COM3 OFF ON ON OFF 3E8 to 3EF 4,5,9,10,11,12,15COM4 OFF ON OFF ON 2E8 to 2EF 3,5,9,10,11,12,15
5634BIF User’s Manual6I/O Port (JS2) SettingIRQ (JS3,JS4&JS5) SettingShort OpenFigure 1-2. Jumper diagramAs Table 1-1 shows, a serial device configured to use COM1 will conflict with anotherserial device configured to use COM3 which happen to select IRQ4, because these portsshare the same interrupt. To avoid this conflict, one of device should use COM4. Similarly,a serial device on COM2 will conflict with a serial device using COM4, because theseports share the same interrupt (IRQ3). In this case, one of the devices should use COM3.Whichever COM port setting you use, make sure the software you are using is set up toaddress that port.For maximum flexibility, your modem supports IRQ2-5 interrupt requests. Typically, youwill use IRQ3 or IRQ4. However assume your PC has a serial printer configured as COM1and serial mouse configured as COM2. If you want to use your modem while printing inthe background, you cannot set the modem to COM3 (which uses IRQ4) because theIRQ4 setting for COM3 conflicts with the printer using COM1, which also uses IRQ4.Setting the modem to COM4 (IRQ3) conflicts with the mouse using COM2 (IRQ3).To solve this problem, you can use Jumper 1(JP1) to select IRQ2 or IRQ5( refer to table1-1). This means that you can print in the background using a printer configured as COM1,use a mouse configured as COM2, and perform modem activities all at the same time!IRQ settings 2 through 5 should be used only if you have no other choice. Not all PCs andDOS versions support IRQ5. IBM PC/AT computers and compatibles should be able touse IRQ2 or IRQ5, so long as the computer does not have a parallel port set up as LPT2or another device that is using IRQ2.4CDACABDB91011351215
5634BIF User’s Manual71.6 Inserting the modemThe internal modem can fit into any available slot in your personal computer. To insert theinternal modem in your personal computer:1. Position yourself so that you can easily access the computer's expansion slots.2. Select any available half-card slot into which you can install the internal modem.3. Remove any slot cover that may be over the slot. Then remove the slot cover andkeep both in a safe place (you will need the screw to secure the internal modem andyou may need the slot cover if you decide to remove the internal modem in the future).4. Hold the internal modem above the slot you selected, making sure the modem's edgeconnectors are pointing down toward the base of the personal computer (see Figure1-3).5. Carefully slide the modem into the slot, applying even pressure to both ends of themodem. Stop inserting the modem when its gold-plated edge connectors are alignedwith and completely fit into the base of the computer.6. If you removed a screw from the slot cover, use that screw to secure the modem in theslot. You may want to test the modem's telephone connection (described in the nextsection) before securing your modem.7. Use the cover-mounting screws to secure the computer cover.Figure 1-3. Inserting the modem1.7 Connecting to the telephone lineUse the following procedure to connect your modem to the telephone line:1. Make sure you have an RJ-11 telephone jack. If you need a modular jack, eitherobtain a telephone adapter from a telephone or electronics store and follow theinstallation instructions provided with the adapter, or have your local telephonecompany replace your existing telephone jack with a modular-type jack and yourexisting telephone cord with a modular cord.2. Unplug your telephone's cable from the wall jack.3. Take one end of the modular telephone cable supplied with the modem and plug itinto the LINE modular telephone jack on the back of the modem ( see Figure 1-3).4. Plug the other end of the telephone cord into the telephone jack on the wall, as you
5634BIF User’s Manual8would any modular telephone.1.8 Connecting to your Fax MachineYour modem is so convenient, it provides a second modular telephone jack that lets youconnect your fax machine to the same telephone line the modem is using. This lets youmanually dial data calls or make voice calls when you are not using your modem.1. Use the following procedure to connect your fax machine to your modem:2. Connect the telephone's modular cord into the PHONE jack on the back of yourmodem (see Figure 1-4).SPKLINEPHONEMIC5634BIFFigure 1-4. Back of the modem1.9 Connecting to the microphone and speakerFor voice message recording and playing, your modem provides MIC and SPK jacks thatlet you connect your microphone and speaker to the modem.Use the following procedure to connect your microphone and speaker to your modem :1. Connect the Microphone speaker plug cord into the MIC and SPK jacks on the back ofyour modem (see Figure 1-4).1.10 Verifying your connection Before you proceed to next step, make sure your connection matches the one shown inFigure 1-5.

Completed modem installationIf you connected the modem to a computer, place the computer into terminal mode andcomplete the configuration information required by the software. Refer to your computermanual to find out the appropriate command to use.Then use the following procedure to verify that your connections:1. Type AT and press the Enter key. If your system is operating properly, your modemsends an OK response to your screen and wait for your next command.If you did not receive a response, make sure your computer is sending commands toyour modem. If this does not solve your problem, contact your computer dealer.2. Use your communication software to prepare your computer to dial a call. Then typeAT D x phone number, where x is either T for touch-tone dialing or P for pulse dialingand phone number is the telephone number that your modem is using.For example, if your modem is connected to the telephone line 555-2121 and Touch-Tone dialing is supported in your calling area, type ATDT 5552121.3. Press the Enter key. You should receive a BUSY response and you should hear thebusy signal through the modem speaker because the modem is calling itself.Your modem is now ready for operation. Refer to the manual that came with yourcommunication software to begin communications. If you will be communicating directlywith your modem, or if you want to find out more about the modem's operation, proceed toChapter 2.−When you turn off your computer, the modem will turn off automatically. It will turnon again when you turn on the computer.
5634BIF User’s Manual10CChhaapptteerr 22 TTyyppiinngg ccoommmmaannddss aanndd rreecceeiivviinngg rreessppoonnsseessChapter 2 describes the format to use when typing modem commands. Chapter 2 alsodescribes the responses that your modem sends to your computer screen when youexecute, or try to execute, modem commands.If you will be using a communication software program to make data calls, you willprobably not need to type commands, because your software program will handle thesetasks for you. Similarly, you will probably not see the responses because your softwareprogram may intercept them.However, if you perform data activities directly with your modem, you will find the formatfor typing modem commands and modem response helpful.2.1 Typing a commandUsing commands, you can have your modem perform a variety of activities, such asdialing or answering a data call or sending a fax. In order to send commands to yourmodem, You must type a command line while your modem is in command mode.2.2 To type a command line :1. Type AT. These characters must precede every command line. (except when you typethe A/ command, described on page 30)2. Type the commands you want your modem to execute. A command line can containup to 40 characters.3. Press the Enter key. The modem will then execute the commands on the commandline.2.3 Correcting a typing mistakeIf you make a mistake while typing a command, press the Backspace key to delete theerror. You can delete every command except AT.2.4 ReadabilityTo make a command line easy to read, you can insert spaces parentheses, hyphens, andother punctuation in your command line. For example :AT M3 DT 9, 1(818)555-1234Your modem ignores spaces and punctuation when executing a command line, but thesecharacters apply to the 40 characters limit.2.5 Typing more than 40 charactersIf you want to type more than 40 characters on a command line, type a regular commandline (up to 40 characters long) and end it with a semicolon as the last character. When
5634BIF User’s Manual11you press Enter, your modem executes the commands and returns to command mode, soyou can type your next command line.2.6 Omitting a parameterSome commands require a numeric parameter such as 0,1, or 2. For example, the Qcommand determines whether your modem sends a modem response after executing amodem command line :Q0 tells the modem to send responses.Q1 tells the modem not to send response.If you type ATQ and press the Enter key without typing a parameter of 0 or 1 after the Q,it's like typing Q0 and the modem will send modem responses.2.7 Repeating a command lineFor your convenience, the last command line you execute remains stored in the modem'smemory until you type a new command line and press the Enter key. If you want to re-execute the last command, type A/.When you want to use the A/ command, you don't need to preface it with the ATcharacters or end it by pressing the Enter key. Just type A/ to have your modemautomatically re execute the last command line.The A/ command is particularly useful when you want your modem to re-execute a lengthycommand line or redial a number that was busy.You can continue using A/ to automatically re-execute the last command line until youtype a new command line that begins with AT or reset your modem, or until your modemloses power.2.8 Modem responsesWhen you send a command to your modem, it sends a response to your computer. Forexample, if you send a modem command to your modem, the modem should respond withOK. You may never see these responses, however because certain communicationsoftware will intercept them before they can be displayed on your computer screen.This section describes the modem responses returned by the modem when youcommunicate directly with the modem. If you will be using a communication softwareprogram to make data calls, you may not see these responses because your softwareprogram will probably intercept the responses.Response setsModem responses can come from one of five response sets. These response sets aredesigned X0, X1, X2, X3, and X4.The response sets determine which modem responses are sent by the modem. They also
5634BIF User’s Manual12define certain dialing characteristics and how the modem handles dial tones and busysignals, as described in the following sections.2.9 Word or numeric responsesModem responses can appear as words or numbers. Your modem is set up to return wordresponses. Word responses are followed by a carriage return and line feed.If your modem is operating under an application that handles character strings inefficientlyor cannot handle them at all, you can use the V0 command to switch to numeric modemresponses. Numeric responses are followed by a carriage return only.If you do not want to receive modem responses at all, you can use Q1 command todisable them. You may want to disable responses entirely if your modem is connected to aprinter and you do not want the modem responses printed.2.9.1 X0 response setThe X0 response set consists of the first five responses in Table 2-1(see page 19). withthis response set, you receive the CONNECT response for all connections, regardless ofthe speed at which they're made.When you send a Dial command line with this response set in effect, the modem will waittwo seconds after receiving your Dial command, then automatically dial the telephonenumber whether or not a dial tone is present This is known as "blind dialing." You maywant to use blind dialing if you will be using the modem in an area that has an irregular orweak dial tone that your modem cannot always detect.2.9.2 X1 response setThe X1 response set consists of the all responses in Table 2-1 (see page 19), except NODIALTONE, BUSY and NO ANSWER. When you send a Dial command with thisresponse set in effect, your modem will blind dial call.2.9.3 X2 response setThe X2 response set consists of all responses in Table 2-1(see page 19), except BUSYand NO ANSWER.When you send a Dial command with this response set in effect, your modem will listenfor a dial tone before dialing. If it does not detect a dial tone within five seconds, it hangsup and returns the NO DIALTONE response.2.9.4 X3 response setThe X3 response set consists of all responses in Table 2-1 (see page 19), except NODIALTONE.When this response set is in effect and you send a Dial command to your modem, yourmodem will blind dial the call. If the telephone number dialed is busy, your modem will
5634BIF User’s Manual13send the BUSY response.2.9.5 X4 response setThe X4 response set is the factory-default response set. It consists of the all responses inTable 2-1(see page 19). This response set allows the modem to detect a dial tone andalso a busy signal.2.10 Correction & compression responsesIf your modem supports the MNP and V.42/V.42bis error-correction and data-compressionprotocols, you can use the Wn command to enable the extended responses shown inTable 2-1(see page 19).l The W command that enables negotiation progress responses is not the samecommand as the W dialing modifier used in dial command lines.The default setting, W0, disables extended responses. With W0, all CONNECT responsesreport the DTE speed.To receive the CARRIER and PROTOCOL responses in Table 2-1, send the W1command. When this command is in effect, the CONNECT response will show the DTEspeed.If you want the CONNECT response to show the DCE speed rather than the DTE speed,send W2 command. With this command, extended responses will be disabled.Modems that support the MNP and V.42/V.42bis error-correction and data-compressionprotocol can also use the \V1 command to append /ARQ to the end of all CONNECTresponses when your modem makes an error-correction data connection with a remotemodem.If you do not want /ARQ appended to the end of CONNECT responses when an error-correction data connection is made, send the \V0 command.Table 2-1.

The profiles will be saved, even when you turn off your modem.When you need to use a certain profile, send the appropriate command.You can save two custom configuration profiles in your modem's nonvolatile memory. Yousave profiles using &Wn command. The n can be the number 0 or 1, which correspondsto the location in nonvolatile memory where you want the profile stored.Using the &Wn command, you can store the following commands (refer to Chapter 5 fordescription of these commands):B1, T, E1, F0, L2, M1, Q0, V1, X4, Y0, &C0, &D0, &G0, &J0, &K3, &L0, &P0, \A3, \B2,%C1, \N3 .........You can also store the following register values (refer to Chapter 6 for a description ofthese registers) :S0=0, S2=43, S6=2, S7=30, S8=2, S9=6, S10=14, S11=95, S12=50, S18=0, S25=5 ...3.1 Storing a profileThe following example shows how you can store a profile. Assume that you want to savethe following commands in profile 0:X1 E0 &C1 &D0 &M0 S0=3To do so :1. Type AT2. Type the commands shown above3. Type the &W0 command as the last command on the command line to save thesecommands as user Profile 0.4. Press the Enter key.

5634BIF User’s Manual19CChhaapptteerr 44 EErrrroorr ccoorrrreeccttiioonn aanndd ddaattaa ccoommpprreessssiioonnYour modem supports sophisticated MNP 1- 4 and V.42 error- correcting protocols. Theseprotocols ensure the transmission of error-free data − even over noisy, error- pronetelephone lines. Your modem also supports the V.42bis and MNP 5 data-compressionprotocols, which maximizes data throughput and significantly reduces the time needed toexchange data.4.1 Error-correction protocolsYour modem includes two error-correction protocols:• MNP level 1 through 4• CCITT V.42When these protocols are used, the two modems perform calculations on each "packet" ofdata being exchanged and compare their values. If the values do not match, the receivingmodem requests the sending modem to re transmit the packet.MNP is an acronym for Microcom Networking Protocol. MNP detects and corrects errorsthat occur when data is exchanged between two systems. Errors can result fromtelephone- line noise and other signal distortions.4.2 V.42V.42bis the accepted international standard for error correction, ratified by ITU-T inJanuary 1990. It is generally felt that the handshake and protocol establishment processof V.42 is superior to that MNP 4. Therefore, it will provide better initial connections onpoor quality telephone lines.Moreover, while the effective data speed of V.42 and MNP 4 are almost identical overnoise-free telephone lines, V.42 provides significantly better performance than the ITU-T-specified MNP4 over noisy telephone lines.4.3 Configuring for auto-reliable operationAuto-reliable operation is the modem's default configuration, so if you haven't given themodem any \N commands, it should already be in auto-reliable mode.Auto-reliable mode lets your modem communicate with both MNP/V.42/V.42bis modemsand modems that do not use MNP/V.42/V.42bis :1. Type AT\N3%C3 (Factory Setting)2. Press the Enter key. Your modem responds with OK. When your modem originates oranswers calls, it will try to make a V.42bis/V.42 connection. If either or both fail, yourmodem will try to make an MNP connection. If that fails, your modem will try to make anormal connection that does not use error correction.

Type AT\N0 and press the Enter key to return to standard operation with buffering. orAT\N1 and press the Enter key to return to standard operation without buffering2. Your modem responds with OK.4.6 MNP5 and V.42bis data-compressionThere are two major data-compression protocols used in data communications, MNP5 andV.42bis. MNP5 was the first data-compression protocol to be developed and provides adata-compression ratio of 2:1.In January 1990, ITU-T ratified the V.42bis data-compression protocol as the internationalstandard. V.42bis performs significantly better than MNP5, providing a data-compressionratio of approximately 3:1 − and in some case, up to 4:1.By supporting both types of data-compression protocols, your modem can communicatewith the installed base of MNP5 and V.42bis modems and modems.To communicate with remote MNP5 modems only1. Type AT%C12. Press the Enter key. Your modem responds with OK. When your modem originates oranswers calls, it will try to make an MNP5 connection.

If you will be usinga data communication software program to send and receive files, you will probably notneed to use these commands, because your software program will handle these tasks foryou. However, if you want to bypass your communication software program and performmodem tasks directly with your modem, you will find the commands described in thischapter helpful.Standard modem commands begin at Table 5-1. MNP/V.42/V.42bis commands begin onpage 37. If a command requires a parameters such as 0 and 1, the parameter is identifiedas n in the left column and described in the right column in the following tables.−Remember that each command, except for +++ and A/, is prefaced by AT andexecuted when you press the Enter key. To review the format used to send modemcommands, refer to Chapter 2.Please refer to Chapter 4 for more information on MNP/V.42/V.42bis error correction anddata compression protocols.Table 5-1.

5634BIF User’s Manual29CChhaapptteerr 66 LLiisstt ooff mmooddeemm SS--rreeggiisstteerrYour modem has S-registers that affect various operating characteristics, let you obtaininformation about the modem, and let you test the modem. Each S-Register has a factory-set value, which you can read or change to fit your particular requirements. Chapter 6explains how to read and change S-Register repeatedly. A sequential list of S-Register isalso provided.6.1 Reading an S-Register valueTo read the current value of an S-Register :1. Type ATSr? from the command mode, where r is an S-Register number.2. Press the Enter key. The modem responds with decimal value of the S-Register , inthree-digit form, followed by OK.To read values from more than one S-Register :1. Type ATSr?Sr? from the command mode and press the Enter key. For example, toread the value of Register S0 (auto-answer after the number of rings specified by thisS-Register value) and S1(count the number of incoming rings), type ATS0?S1? fromthe command mode.2. Press the Enter key. The modem displays the first S-Register value, a carriage return,the next S- Register value, a carriage return, and OK(or 0).6.2 Changing an S-Register value To change an S-Register value, use the Sr=n command, where r is an S-Register numberand n is the new value you want to assign to the S-Register. For example, to have themodem auto-answer incoming calls after the third ring:1. Type ATS0=3 from the command mode.2. Press the Enter key. The modem responds with OK or 0 to show it has executed yourcommand and changed the S-Register value. The value remains in effect until themodem is turned off and on, or reset. The modem then revert to its default S-Registervalues (in this case, Register S0 returns to a value of 0, disabling auto answer).6.3 S-Register descriptionsTable 6-1 summarizes the modem S-Register, their default values, and their functions.

Applicable toerror-correction connection only. This registercan be used to ensure that data in the modembuffer is sent before the modem disconnects.If S38 is set to a value between 0 and 254, themodem will wait that number of seconds for theremote modem to acknowledge all data in themodem buffer before disconnecting. If timeexpires before all data is sent, the NOCARRIER result code will be issued to indicatedthat data has been lost. If all data is transmittedprior to time-out, the response to the H0command will be OK.If S38 is set to 255, the modem does not time-out and continues to attempt to deliver data inthe buffer until the connection is lost or the datais delivered.

Ifyou do so, find out their IRQ settings from your computer dealer or from the hardwaremanuals.7.1 FOR WINDOWS 95n Add a COM Port1. Please choose START then Settings, then Control Panel. In Control Panel, doubleclick on Add New Hardware. In the "Add New Hardware Wizard" Click on "Next>" button. It will then ask you if you want Windows 95 to search for New Hardware,click on YES, and then the "Next >" button. Read the Warning, and if you agree,click on "Next >". Now wait for the Wizard to complete its inspection of your systemconfiguration. You can click on "Details" and if all is correct, then click on "Finish"button. Then when it asks, click on "Yes" to reboot your computer. 2. Now go to START, then SETTINGS, then Control Panel. Double Click on System.Then click on the Device Manager TAB. Double Click on "Ports (COM & LPT)".Whatever COM ports show up, you cannot use for the modem, unless you disablethem first in the BIOS of you COMPUTER, ON the Motherboard or on your I/O Card.If you choose to disable one of your current ports to put the modem in, then rerun thistest to make sure that it was actually disabled correctly. 3. You can now continue to OPTION 1 of this section.n Refer to Chapter 7 to continue the installation of the modem7.2 FOR WINDOWS 3.1x or DOSTurn your computer on and go to the "C" prompt (C:\>).If you have MS-DOS 6.0, or higher, or MS-Windows 3.1x, type MSD (Microsoft Diagnostic)at "C" prompt. This will not work if you only have Windows 95, (see above section).MSD is going to give you information on your computer system. Look and see if youcan locate an entry call "COM Port." There should be a number right next to that entryidentifying the number of COM ports you have. Write the number down on a piece ofpaper.Press "C" to go into the COM Port screen.
5634BIF User’s Manual44Write the port addresses for each COM Port down. Regardless of what MSD says,"03F8" is COM1, "02F8" is COM2, "03E8" is COM3, and "02E8" is COM4. If it has"02E8" under COM3, don't worry about it. It just means you skipped a COM Port, this isvery common. You only have to go by the port addresses.OPTION 1If you only have "03F8" in the COM Port screen and do not have any sound, network,scanner card, bus mouse, or other device using IRQ3, set your modem's switches orjumpers to COM2 IRQ3 according to the user's manual that came with your modem (bothCOM and IRQ must be set). If you only have "02F8" for COM port, set your modemto COM1 IRQ4, again following the directions of your Modem User's manual.OPTION 2If you have both "03F8" and "02F8" and do not have any sound, network, scanner card,bus mouse, or other device using IRQ5, set your modem to COM3 IRQ5.OPTION 3If you have "03F8" and also have "02E8" and you do not have any sound, network,scanner card, bus mouse, or other devices using IRQ5, set your modem to COM2 IRQ5.OPTION 4If you have "03F8" and also have "02E8" and you do have another device using IRQ5,please consult your "Multi I/O Card User's Manual" and have COM4 "02E8" IRQ3disabled. This "Multi I/O Card User's Manual" ought to come with your computer system.Check with your computer dealer if you can't find one in the package. Set your modemto COM2 IRQ3 after COM4 IRQ3 is disabled on the I/O card.OPTION 5If you have both "03F8" and "02F8" and you do have another device using IRQ5 while youdon't have any external device connected to COM2 "02F8", have COM2 "02F8" IRQ3 onyour I/O card disabled. Set your modem to COM2 IRQ3 after COM2 IRQ3 has beendisabled on your I/O card.OPTION 6 (depends on your system's multi-I/O card)If you have both "03F8" and "02F8" and do have another device using IRQ5 while there isan external device connected to COM2 "02F8" and a serial mouse is connected to COM1"03F8," you can try to put your modem on COM4 IRQ3. However, this is not alwaysguaranteed to work. It is to our experience that whether or not this kind of setting worksor not depends a lot on the multi-I/O card itself. Sometimes the I/O card does not like toshare IRQ (IRQ3 in this case) with another device. Sometimes this setting will work fora while and suddenly stopped working. Sometimes it will work flawlessly. The PCBus architecture was not designed to share IRQ's.
5634BIF User’s Manual45OPTION 7If you have a setting that matches Option 6 above and Option 6 does not work on yoursystem, you can try to move the device that's using IRQ5 to an unused IRQ and set yourmodem to COM3 IRQ5. If the device that's using IRQ5 does not support other IRQ's,you have ran out of available IRQ. Consult your local dealer or a consultant to see ifthey can give you some advice. You must also realize that if your system is fully loadedwith no available COM Port or IRQ, another device must be sacrificed (disabled) to makeroom for the fax modem.When you find the COM Port and IRQ setting for your modem, set the modem accordingto the instructions in your Fax Modem User's manual. Turn your computer off, unplugthe power cord, remove the cover to your computer, locate an available expansion slot onthe motherboard, remove the screw that's holding the slot cover if there is one, andcarefully slide the modem into the slot completely. Secure the modem in the slot withthe screw. Connect your DEDICATED phone wire to the fax/modem's "LINE" jack.You may want to install the software that came with the package and test the modembefore you put the computer cover back. But be careful not to touch any systemcomponents with the power cord plugged into the wall socket.NOTE: Windows 3.1x Systems (COM Port Packing)If you are skipping COM3, and you are installing any Windows based communicationssoftware, you will need to add the following two lines to your SYSTEM.INI file's [386Enh]section:Example: COM3IRQ=-1 COM3BASE=03E8This applies in general to any skipped COM Port, where 'x' is the Port Number skipped. COMxIRQ=-1 COMxBASE= {note the appropriate port address}Port Addresses COM1 = 03F8 COM2 = 02F8 COM3 = 03E8 COM4 = 02E8
