If you need assistance, refer to the manual that accompaniedyour equipment or contact your computer dealer.3. After making the connection, check your computer or terminal requirements for theCarrier Detect and Data Terminal Ready signals. The &C command affects the CarrierDetect signal, and &D command affects the Data Terminal Ready signal. Refer toChapter 5 List of modem commands.1.6 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, either obtaina telephone adapter from a telephone or electronics store and follow the installationinstructions provided with the adapter, or have your local telephone company replaceyour existing telephone jack with a modular-type jack and your existing telephone cordwith a modular cord.2. Unplug your telephone's cable from the wall jack.3. Take one end of the modular telephone cable supplied with your modem and plug intothe LINE jack on the back of the modem (see Figure 1-1).4. Plug the other end of the telephone cord into the telephone jack on the wall.
5634RCS User’s Manual61.7 Connecting to your telephoneYour modem is so convenient. It provides a second modular telephone jack that lets youconnect your telephone 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.Use the following procedure to connect your telephone to your modem:1. Connect the telephone's modular cord into the PHONE jack on the back of yourmodem (see figure 1-1).2. Lift your telephone's handset and listen for a dial tone.1.8 Connecting to an AC outletUse the following procedure to connect your modem to an AC outlet:1.

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 softwaremanual to find out which commands to use.Then use the following procedure to verify your modem connections:1. Type AT and press the Enter key. The RD and TD LEDs flash on the modem frontpanel. If your system is operating properly, your modem sends an OK response to yourcomputer screen and wait for your next command.If the LEDs did not FLASH, or if you did not receive a response, make sure your computeris sending commands to your modem at a speed of 300, 1200, 2400, 9600, 19200, 38400,57600 or 115200bps. 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 typeATD 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 usingFor example, if your modem is connected to the telephone line 555-2121 and Touch-Tonedialing is supported in your calling area, type ATDT 555 21213. 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 communication. If you will be communicating directlywith your modem, or if you want to find out more about the modem's operation, proceed touse's manual.

Yourcomputer sends this sign al when the computer is ready to send or receivedata ( DTR is ON ). This LED does not work with Macintosh, which usesthe DTR signal for hardware flow control purposes.MR MR is the Modem Ready LED, This LED goes ON when your modem isconnected to an AC outlet and turned on.
5634RCS 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 line1. Type AT. These characters must precede every command line. (except when you typethe A/ command, described on page 31)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.
5634RCS User’s Manual112.5 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. Whenyou 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 software
5634RCS User’s Manual12program 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 alsodefine 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. with this responseset, you receive the CONNECT response for all connections, regardless of the speed atwhich 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, except NO DIALTONE,BUSY and NO ANSWER. When you send a Dial command with this response 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, except BUSY and NOANSWER.
5634RCS User’s Manual13When 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, except NO DIALTONE.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 willsend 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. This response set allows the modem to detect a dial tone and also a busysignal.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.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.

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:l MNP level 1 through 4l 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.

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.

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 valueTo 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:Type ATS0=3 from the command mode.1. 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.
5634RCS User’s Manual34Table 6-1 S-Register descriptionS-Register Range Default DescriptionS0 0-255rings 0Auto-answerAssigning a value from 1 to 255 in RegisterS0 tells the modem how many rings mustoccur before it can auto-answers calls. Thedefault, 0, turns off the auto-answer feature.S1 0-255rings 0Count incoming ringsRegister S1 counts the number of incomingrings when your telephone line rings. Whenthis value equals the value in Register S0,the modem auto-answer calls. This S-Register resets approximately 8 secondsafter the last ring.S2 0-255,ASCII 43(+) Escape character valueRegister S2 sets the ASCII value of escapecharacters, that switch the modem from datamode to command mode without losing theconnection to the remote modem. Valuesgreater than 127 disable the escapefeature, preventing a return to the commandmode. To return to command mode with theescape characters disabled, the remotemodem must hang up or an ON-to-OFFtransition of the DTR interface signal mustoccur with &D1, &D2 or &D3 in effect.S3 0-127,ASCII 13(CarriageReturn)Carriage return characterRegister S3 sets the ASCII value of thecarriage return (end-of-line) character, Thisis the character used to end the commandline(and have the modem execute the line)and also the character that follows modemresponses.S4 0-127,ASCII 10(Line Feed) Line feed characterRegister S4 sets the ASCII value of the linefeed character. The modem sends thischaracter after a carriage return only whenword responses are sent (V1 command ineffect). If a line feed characters is notwanted, change this register value to a nullcharacter.

To change this value, assign an ASCIIvalue between 0 and 32 or greater than127. Do not use values between 33 and 126since they correspond to printable ASCIIcharacters.S6 4-255seconds 4Dial tone wait timeRegister S6 determines how long themodem waits before dialing the first digit inDial command line. This feature isconvenient when it takes longer than twoseconds to obtain a dial tone.S7 1-255seconds 50 Carrier wait timeRegister S7 tells the modem how manyseconds to wait for a remote modem'scarrier signal before hanging up. The S7value can be increased if the modem doesnot detect a carrier within the specified time.If the modem detects a remote carrier signalwithin the specified time, it sends aCONNECT response and enter data mode.If it does not detect a remote carrier withinthe specified time, it sends NO CARRIER ,hangs up, and remains in command mode.S8 0-255seconds 2Comma pause time for dial delayRegister S9 tells the modem how manyseconds to pause for each comma (,) in aDial command line. The comma is usedwhen dialing through a PBX or other specialtelephone service to wait for an outsidetelephone line.S9 1-255tenthsof asecond6Carrier detect response timeRegister S9 tells the modem how long theremote modem's carrier signal must bepresent so the modem does not mistake thesignal for a busy signal, ring, or voice. Thedefault setting requires the modem to thecarrier signal for at least 0.6 seconds beforerecognizing it.

Increasing thisvalue to 255 slows the dialing rate to 1.9digits per second. Do not select a value lessthan 50 milliseconds. (Register S11 doesnot effect pulse dialing, which is fixed at 10pulses per second.)S12 0-2551/50seconds50 Escape character guard timeRegister S12 controls the time delayrequired before and after typing the escapecharacters. The default setting, 50, equalsone second. To reduce the chance thattransmitted data is mistaken for escapecharacters, the S12 value can be increased,but this makes using the escape characterstime-consuming. If a small value is used, itmay be hard to type the three escapecharacters fast enough, especially if theguard time is less than the time needed tosend 1 character at the current transmissionspeed. If S12=0, there will be no timerequirement for typing escape characters.

If youdo so, find out their IRQ settings from your computer dealer or from the hardware manuals.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.
5634RCS User’s Manual52n Refer to Chapter 8 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.Write 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 card, networkadapter, scanner card, bus mouse, or other device using IRQ3, set your modem'sswitches or jumpers to COM2 IRQ3 according to the user's manual that cames with yourmodem (both COM and IRQ must be set). If you only have "02F8" for COM port, setyour modem to 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.
5634RCS User’s Manual53OPTION 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 our experience that whether or not this kind of setting works ornot 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.OPTION 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=03E8
