If you will be installing the modem into adifferent computer, refer to the manual that accompanied your computer orcontact your computer dealer for instructions on installing the modem in yourpersonal computer.1.3 Removing the computer coverTurn off the personal computer's power. No power must be applied to yourcomputer when you install the internal modem and computer could bedamaged.Make sure you can freely access the back of the personal computer.Unscrew the necessary screws to loosen the computer cover. Then set the
4screws in a safe place and remove the computer cover.1.4 Inserting the modemThe internal modem can fit into any available PCI slot in your personalcomputer. To insert the internal modem in your personal computer:1. Position yourself so that you can easily access the computer's expansionslots.2. Select any available half-card slot into which you can install the internalmodem.3. Remove any slot cover that may be over the slot. Then remove the slotcover and keep both in a safe place (you will need the screw to secure theinternal modem and you may need the slot cover if you decide to removethe internal modem in the future).4. Hold the internal modem above the slot you selected, making sure themodem's edge connectors are pointing down toward the base of thepersonal computer (see Figure1-1).5. Carefully slide the modem into the PCI slot, applying even pressure to bothends of the modem. Stop inserting the modem when its gold-plated edgeconnectors are aligned with and completely fit into the base of thecomputer.6. If you removed a screw from the slot cover, use that screw to secure themodem in the PCI slot. You may want to test the modem's telephoneconnection (described in the next section) before securing your modem.7. Use the cover-mounting screws to secure the computer cover.Figure 1-1. Inserting the modem
51.5 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 obtain a telephone adapter from a telephone or electronics store andfollow the installation instructions provided with the adapter, or have yourlocal telephone company replace your existing telephone jack with amodular-type jack and your existing 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 modemand plug it into the LINE modular telephone jack on the back of the modem(see Figure 1-2).4. Plug the other end of the telephone cord into the telephone jack on the wall,as you would any modular telephone.1.6 Connecting to your telephoneYour modem is so convenient, it provides a second modular telephone jackthat lets you connect your telephone to the same telephone line the modem isusing. This lets you manually dial data calls or make voice calls when you arenot using your modem.Use the following procedure to connect your telephone to your modem:Connect the telephone's modular cord into the PHONE jack on the back ofyour modem (see Figure 1-3).Lift your telephone's handset and listen for a dial tone.

Completed modem installationIf you connected the modem to a computer, place the computer into terminalmode and complete the configuration information required by the software.Refer to your computer manual 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, yourmodem sends an OK response to your screen and wait for your nextcommand.
7If you did not receive a response, make sure your computer is sendingcommands to your modem. If this does not solve your problem, contactyour computer dealer.2. Use your communication software to prepare your computer to dial a call.Then type AT D x phone number, where x is either T for touch-tonedialing or P for pulse dialing and phone number is the telephone numberthat your modem is using.For example, if your modem is connected to the telephone line 555-2121and Touch-Tone dialing is supported in your calling area, type ATDT5552121.3. Press the Enter key. You should receive a BUSY response and you shouldhear the busy signal through the modem speaker because the modem iscalling itself.Your modem is now ready for operation. Refer to the manual that came withyour communication software to begin communications. If you will becommunicating directly with your modem, or if you want to find out more aboutthe modem's operation, proceed to Chapter 2.1.8 Windows95/98ModemDriver Installation(PNP)1. Install the PnP modem into an available slot.2. Turn On your computer.3. As you enter Windows you should receive a message saying “PCIcommunication Device”, than “5634PCV V90 modem”.4. Windows will identify the modem and then present you with threechoices.Do not install a driverDriver from disk provided by manufacturerSelect from a list of alternate drivers.Select Driver from disk provided by manufacturer. Windows will askyou to insert your disk. Put the disk in your drive and select right inf
8file then hit OK. You will be presented with a listing of Topic modems.Select the model number of your modem and then hit OK.5. Click Finish and Windows will install the driver, and then finishbooting.6. To check the modem installation open Control Panel and thenModems. Click on the Diagnostics tab. Click on the port which listsyour modem. Click on More Info. Your modem should report backwith modem information. Your modem is functioning properly.1.9 Windows NT 4.0 ModemDriver Installation1. Install the PnP modem into an available slot.2. Insert Setup program for Windows NT drivers’ disk into drive A or B.3. Execute the “Setup” program to install the PCI agent driver.4. Then, after the installation is completed, reboot PC.5. After PC is rebooted and NT is running, follow the steps described insection 1.1 to add the modem and its drivers.NOTE: Microsoft does not support plug and play in Windows NT 4.0.1.10 Linux Red Hat 6.0Modem Driver InstallationA. Manual mode:1. At path /proc, find file pci then use vi editor to find Topic vender ID “151f”and the I/O-address, IRQ-number Linux assign to Topic modem. For example : cd /proc vi pci ………………………………………… Vendor id=151f. Device id=0. Medium devsel. IRQ=5. I/O at 0xe400 [0xe401]. (type :q to quit vi)2. At path /dev, use setserial tty-number uart 16550A irq IRQ-number port I/O-
9addressFor example : setserial ttyS2 uart 16550A irq 5 port 0xe4003. At path /dev, remove default modem link then link modem to the tty youassign in step 2For example : rm modem ln –s ttyS2 modem4. Now, you can use minicom to test the modem by type ATI3 to make sure themodem is Topic modem.For example : minicom ……………….. ATI3B. Automatic Mode1. Copy topic.modem excutable file to /bin2. Copy script file rc.serial to /etc/rc.d3. When Linux boot again you can see the message " Setup topic modem …" or you can run topic.modem directly.4. You can use minicom to check Topic modem.1.11 MS-DOS ModemDriver InstallationIntroductionThis program intends to provide the function for hardware resourceconfiguration via 5634PCV internal modem card. It is only can be executed inDOS environment, Windows DOS prompt is inhabited to run this program.InstallationPrior launching the program, 5634PCV PCI modem card must be installed inthe PC in advance. Besides, it can be used to configure the multiple PCI cards.ConfigurationWhen the program is launched, it will search the 5634PCV PCI card first. If nocard is found, an error message will be shown and the program will beterminated. If only one card is enumerated, a configuration dialog window willbe popped up immediately. User can set and the IO port address and interruptnumber of PCI card in this configuration dialog. After setting, user may select
10‘OK’ button to set the desired setting to PCI card and exit the program. If userselects ‘Cancel’ button, the changed setting will not be effective. Please notethe changed setting will not be stored and saved in PC BIOS or PCI card afterPC is rebooted.When ‘OK’ button is selected, the program will automatically test the IO portand interrupt number to see whether the PCI card can be operated normallywith the desired setting. If either IO or IRQ verification is failed, the programwill pop up a warning message and let user to set another value.If multiple cards are detected, the program will show a list box to demonstratethe found cards in the sequence (i.e., modem1, modem2...modemN). Thenthat, user may select any one of the modem from the list to configure.DiagnosisThere is push button ‘Diagnose’ existed in the configuration dialog. When thisbutton is selected, the program will issue some ‘AT’ commands to modem anddisplay the result for analysis. Before sending the command to UART of PCIcard, the program will first verify the IO and interrupt setting. If the verificationis failed, it will stop the diagnosis and prompt a waning message to the screen.After the diagnosis is done, it will show the PCI information, including device ID,vendor ID, subsystem ID and subsystem vendor ID. Moreover, the versionnumber and built date of modem controller and DSP code will be shown aswell.Command LineThis program also provides the function to set IO and interrupt number in thecommand line operation. Two optional arguments are defined as follows:-io <I/O window address, e.g. 0x240,0x300...>-int <Hardware interrupt number, e.g. 3,4,5...>When any one of the arguments is given when the program is run in DOScommand line, the program will assume the ‘Command line’ operation isdesired. Then that, it will not prompt the window interface and directly set theIO and interrupt number of PCI card by the given value. After setting, theprogram will be terminated immediately. Please note the both arguments mustbe given in the same time. If any one of argument is missed, the program willnot set the value to adapter and the error message will be shown.
11Chaper 2 AT Commands SetAT commands are issued to DTE to control the modem's operation. ATcommands can only be entered while the modem is in command mode. Exceptfor the A/ command and the +++ escape command, all commands must beprefixed with the attention code AT. For instance, the “A” command (below)would be entered as: "ATA<CR>". Without the AT prefix, the command linecannot be executed. For example: The format for entering AT commands is“ATXn” where X is the AT command, and n is the specific value for thatcommand.More than one command can be placed on a single line and (if desired)separated with spaces for readability. Once the carriage return (Enter) key ispressed, the command line is executed. A line with no carriage return isignored. Any command issued is acknowledged with a response in either textor numeric values known as result codes. In the following, all commands,command-values and result code recognized by the modem are shown; anyentries other than those shown cause the ERROR result code. The modemaccepts either upper or lower case characters in the command line andignores any spaces within or between commands. Typing errors can becorrected with the Backspace key. Exceptions are noted in the description ofspecific commands.+++AT Escape SequenceThe escape sequence allows the modem to exit data mode and enter onlinecommand mode. While in online command mode, you may communicatedirectly to your modem using AT commands. You may return to data mode byissuing the ATO command.2.1 Data Mode CommandA/ Executes Last CommandWhen modem receives this command, modem executes the last commandstring entered.

Themodem uses a line feed character in command mode when it responds to thecomputer.Range: 0-127, ASCII decimalDefault: 10 (line feed)Units: ASCIIS5 Command Line Editing Character (User Defined)This register sets the character recognized as a backspace and pertains toasynchronous only.Range: 0-127, ASCII decimalDefault: 8 (backspace)Units: ASCIIS6 Wait Before DialingThis register sets the length of time, in seconds, that the modem must wait(pause) after going off-hook before dialing the first digit. The modem alwayspauses for a minimum of two seconds, even if the value of S6 is less than twoseconds. Waiting for dial tone call progress features (W dial modifier in the dialstring) will override the value in register S6. This operation, however, may beaffected by some ATX options according to country restrictions.Range: 2-10Default: 2Units: secondsS7 Connection Completion TimeoutThis register sets the time, in seconds, that the modem must wait beforehanging up because carrier is not detected. The timer is started when themodem finishes dialing (originate), or goes off-hook (answer). In originatemode, the timer is reset upon detection of an answer tone if allowed by countryrestriction. The timer also specifies the wait for silence time for the @ dial
27modifier in seconds. S7 is not associated with the W dial modifier.Range: 1-255Default: 45Units: secondsS8 Comma Dial Modifier TimeThis register sets the time, in seconds, that the modem must pause when itencounters a comma (,) in the dial command string.Range: 1-255Default: 2Units: secondsS9 Carrier Detect Response TimeRegister S9 sets the time the remote modem's carrier signal must be presentfor the local modem to recognize it. This feature ensures that your modemdoes not mistake a busy signal, ring, or voice for the carrier signal. The valueof this register is in tenths of a second. The default value is 600 ms , althoughyou can change it from 1 to 255. For example, entering a value 13 means thatthe remote modem's carrier signal must be present for 1.3 seconds for thelocal modem to recognize it. Setting this value higher increases the chancesthe modem will not mistakenly identify the carrier signal.S10 Automatic Disconnect Delay after Carrier LossThis register sets the length of time, in tenths of a second, that the modemwaits before hanging up after a loss of carrier. This allows for a temporarycarrier loss without causing the local modem to disconnect. The actual intervalthe modem waits before disconnecting is the value in register S10.Range: 1-254Default: 14Units: 0.1 secondsS11 DTMF Dialing SpeedThis register determines the dialing speed which is prefixed for each country.Range: 50-255Default: 95Units: 0.001 seconds

30S25 Data Terminal Ready DelayWhen Modem is on-line, it will ignore a Data Terminal Ready signal lasting lessthan the value of this register. In this mode, the values for this register are 0 to255 in hundredths of a second, and the default value is 0.05 seconds. If youwill be entering synchronous mode after dialing asynchronously, this registerdetermines how long the modem waits before looking for the Data TerminalReady signal. This lets you detach the asynchronous terminal and connect asynchronous terminal while remaining in the Data Mode. The default value is 5Range: 0-255Default: 5Units: 0.01 secondsS26 Request To Send-to-Clear To Send DelayThis register affects synchronous operation only and applies only when youare using the &R0 command. This register determines how long the modemwaits to turn on the Clear To Send signal after a Request To Send OFF-to-ONtransition in 10 ms increment.

A value of zero prevents standby mode.Note: If a number between 1 and 4 is entered for this register, it will set the
31value to 5, and the inactivity before standby will be 5 s. This is done forcompatibility with previous products which allowed time-outs down to 1 s.Range: 0, 5-255Default: 10S95Bit Value Function0,1 Mapping to ATWn2 Mapping to AT\V3 Mapping to ATN4 Mapping to AT*OS96 Local Phone StatusThis register tells the status of the Local Phone.
