Sound Card and Speaker Connections (If you have the Voice Option)  
For voice mail or speakerphone applications, use a 3.58mm (9/64-inch) plug male-to-male stereo patch  
cord to connect the LINE OUT jack on the modem to the LINE IN jack on your sound card. If your sound  
card does not have a LINE IN jack, use its MIC jack.  
This will allow you to hear modem activity whether it is originating or answering a call, or playing a  
recorded message. If you do not have a sound card, you can plug an amplified speaker into the LINE  
OUT jack.  
Step 3: Install the Modem Driver  
If you use Windows 95 or newer, you must install the modem driver. The modem driver tells Windows  
how to control the modem. If you use a Linux operating system, please see Appendix F for installation  
instructions. If you use the SCO OpenServer operating system, please see Appendix G.  
Installing the Modem Driver in Windows 95/98/Me/2000/XP  
1. Make sure your modem is connected properly, and then turn on your computer. Windows should  
detect your new modem and open the Install New Modem wizard.  
2. Insert the system CD into your CD-ROM drive, and then click OK.  
3. Windows installs the modem driver.  
4. Click Finish to exit.  
Changing the Windows 95/98/Me COM Port Assignment  
Unlike an external modem, the MultiModemZPX contains its own serial port. When Windows detects  
the MultiModemZPX, it assigns the next available COM port to it. Since COM1 through COM4 are  
standard serial ports in Windows computers, Windows typically assigns COM5 to the modems serial  
port.  
If Windows assigns the modem to a COM port higher than 4, then certain legacy software applications will  
not recognize the modem. To correct this situation, Multi-Tech Systems provides two additional driver  
files on the MultiModemZPX CD that may be used to reassign the modem to either COM3 or COM4. To  
reassign the COM port:  
1. Insert the MultiModemZPX CD into your computers CD-ROM drive.  
2. Click Start | Settings | Control Panel. Double-click the System icon.  
3. Select the Device Manager tab, and double-click the Modem icon.  
4. Double-click MT5634ZPX-PCI to go to the Properties dialog box.  
5. Select the Driver tab. Click the Update Driver button and follow the Update Device Driver wizard  
prompts. The wizard requests you to specify the path of the new driver. If youd like to reassign your  
modem to COM3, type D:\COM-3\pcicom3.inf, where D: is the drive letter associated with your  
computers CD-ROM drive. If you want to reassign your modem to COM4, type D:\COM-  
4\pcicom4.inf and continue with the wizards instructions.  
6. When the wizard completes its installation, your modem should be reassigned to the new COM port.

Verifying the Windows 95/98/Me Configuration  
Windows assigns an interrupt request (IRQ) number for your modem. Because the number of IRQs is  
limited, a computer with several accessories may not have an available IRQ for your new modem. In  
that case, you may have to decide which of your other accessories you can modify or do without.  
Be aware that resource settings should be changed only by users with expert knowledge of computer  
hardware and hardware configurations.  
Note: Changing resource settings improperly can disable your hardware and can cause your computer  
to malfunction or be inoperable.

Info causes Windows to send commands to and receive responses from the modem. The system also  
displays information about the modems COM port.  
9. Write down the modems port, interrupt, address, and highest speed. You will need this information  
to configure any legacy (nonWindows) communications software you install.  
Port: COM ______ Interrupt: _______ Address: _________ Speed: _________  
10. Click the General tab. Select Multi-Tech Systems MT5634ZPX-PCI, and click Properties to review  
the modems default communications settings. Do not change any settings unless you have special  
requirements.  
11. Click Dialing Properties and review your dialing settings. If you are required to dial 9 to get an  
outside line, type 9 in the local and long distance boxes. If you have Call Waiting service, disable  
Call Waiting to prevent it from interrupting a data or fax transmission. When you are finished, click

Step 5: Install PhoneTools  
You can use PhoneTools to setup the operation of your modem. Multi-Tech includes this data  
communications software program on the product CD shipped with your modem. In general, the  
modem will work with most data communications software programs. Data communications software  
gives you access to commands that govern how the modem operates; that is, how the modem handles  
incoming and outgoing data streams, etc.  
1. Insert the MultiModemII system CDinto your CD-ROM drive. Allow Autorun to bring up the  
introductory screen.  
2. Click on the PhoneTools icon and choose the appropriate country/language.

3 Remote Configuration  
MultiModemZPX User Guide  
Chapter 3 - Remote Configuration  
Remote configuration is a network management tool that allows you to configure MT5634ZPX and  
MT5634ZBA modems anywhere in your network from one location. With password-protected remote  
configuration, you can issue AT commands to a remote modem for maintenance or troubleshooting as if  
you were on site.  
Basic Procedure  
The following steps are valid regardless of whether the connection is established by the local or the  
remote Multi-Tech modem.  
Note: For this procedure, the remote computer must be running, and a communication program  
must be ready for a data connection, which will be indicated by a lighted TR indicator on the front  
of the modem.  
1. Establish a data connection with a remote MT5634ZPX or MT5634ZBA modem.  
2. Send three remote configuration escape characters followed by AT and the setup password, and  
press ENTER. Example: %%%ATMTSMODEM. You have four tries to enter the correct password  
before being disconnected. If the password is correct, the remote modem responds with OK.  
3. Type AT commands to configure the remote modem.  
4. When you have finished configuring the remote modem, save the new configuration by typing  
AT&W0 and pressing ENTER.  
5. Type ATO and press ENTER to exit remote configuration. You can now break the connection in the  
normal way.  
Setup  
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who has  
the User Guide knows the default setup password, you should change the password and possibly also the  
remote configuration escape character.  
To Change the Setup Password  
1. Open a data communications program such as HyperTerminal or PhoneTools.  
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the  
MTSMODEM password with xxxxxxxx) and press ENTER. The modem responds with OK if the setup  
password is correct, and ERROR if it is wrong.  
3. To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then  
press ENTER. The password can include any keyboard character, and can be up to eight characters  
long. The modem responds with OK.  
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the  
same case as you set it up.  
4. The new password is saved automatically. You can now either enter more AT commands or exit the  
data communications program. The next time you wish to set up the modem, you must use the new  
password.

3 Remote Configuration  
MultiModemZPX User Guide  
To Change the Remote Escape Character  
To further improve security, you can change a remote modems remote configuration escape character ei-  
ther locally or remotely. The remote configuration escape character is stored in register S9. The factory  
default is 37, which is the ASCII code for the percent character (%). Setting S9 to 0 (zero) disables remote  
configuration entirely.  
CAUTION: If you do this remotely, you wont be able to change it back remotely.  
1.  
2.  
Establish a remote configuration link with the remote modem as described in Basic Procedure.”  
Type ATS9=n, where n is the ASCII code for the new remote configuration escape character, and  
then press ENTER.  
3.  
4.  
Save the new value by typing AT&W and pressing ENTER.  
Type ATO and press ENTER to exit remote configuration.

4 Troubleshooting  
Chapter 4 - Troubleshooting  
Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a  
successful connection, or if you experience data loss or garbled characters during your connection, it is  
possible that the modem is defective. However, it is more likely that the source of your problem lies  
elsewhere. The following symptoms are typical of problems you might encounter:  
The modem does not respond to commands.  
The modem cannot connect when dialing.  
The modem disconnects while online.  
The modem cannot connect when answering.  
File transfer is slower than it should be.  
Data is being lost.  
There are garbage characters on the monitor.  
The modem doesnt work with Caller ID.  
Fax and data software cant run at the same time.  
The voice functions dont work.  
If you experience problems, please check the following possibilities before calling  
Technical Support (see Appendix D).  
The Modem Does Not Respond to Commands  
Make sure you are issuing the modem commands from data communications  
software, either manually in terminal mode or automatically by configuring the  
software. (You cannot send commands to the modem from the DOS prompt.)  
Make sure you are in terminal mode in your data communications program,  
then type AT and press ENTER. If you get an OK response from your modem,  
your connections are good and the problem likely is in the connection setup in  
your communications software.  
If you dont get an OK, make sure you have properly configured the port in your  
communications program. Most legacy (prior to Windows 95) communications  
programs connect to the COM port when the software loads and remain  
connected until the program terminates. Some programs can disconnect without  
exiting the program. If this is the case, try issuing the softwares connection  
command. If more than one communications program is open, they may conflict  
with each other. Make sure all other communications programs are closed, and  
then try to make the connection again.  
If you are using DOS or Windows 3.1 communication software, make sure the  
initialization string includes &F as the first command, to cancel any leftover’  
command that could affect the modems operation.  
Your communication software settings might not match the port the modem is  
connected to. Make sure the COM port you chose during setup matches the COM  
port set in your communications software. See Chapter 2 for more information.

4 Troubleshooting  
Another expansion card, such as a sound or game card, might be using the same  
COM port, memory address, or interrupt request (IRQ) as your modem. See  
Chapter 2 for information on verifying the configuration for your operating  
system. Look for conflicts with other devices installed on your computer.  
Resources are assigned at power-up by the computers BIOS. If the resources  
assigned to the MultiModemZPX-PCI conflict with the resources of another  
device, the resources of the second device have to be changed. Select the port the  
conflicting device is on and change it to resolve the conflict. If you need to  
change switches or jumpers on the conflicting device, refer to the devices  
documentation.  
If you have another MultiModemZPX-PCI, install it and try to make a  
connection.  
The modem might have a problem beyond the scope of this user guide. If you  
have another Multi-Tech modem, try swapping modems. If the problem goes  
away, call Technical Support for assistance.  
The Modem Cannot Connect When Dialing  
Reasons why the MultiModemZPX-PCI may fail to connect include:  
lack of a physical connection to the telephone line.  
a wrong dial tone.  
a busy signal.  
a wrong number.  
no modem at the other end.  
a faulty modem, computer, or software at the other end.  
incompatibility between modems  
poor line conditions.  
You can narrow the list of possibilities by using extended result codes. Extended  
result codes are enabled by default. If they have been disabled, include V1X4 in the  
modems initialization string, or in terminal mode enter ATV1X4 and press ENTER.  
When you dial again, the modem reports the calls progress.  
If the modem reports NO DIALTONE, check that the modems telephone line  
cable is connected to both the modems LINE jack (not the PHONE jack) and the  
telephone wall jack. If the cable looks secure, try replacing it.  
If that doesnt work, the problem might be in your buildings telephone  
installation. To test the building installation, plug a telephone into your modems  
telephone wall jack and listen for a dial tone. If you hear a dial tone, your modem  
might be installed behind a corporate phone system (PBX) with an internal dial  
tone that sounds different from the normal dial tone. In that case, the modem  
might not recognize the dial tone and might treat it as an error. Check with your  
PBX personnel or the PBX system manual to see if you can change the internal dial  
tone. If you cant, change your modems initialization string to replace X4 with  
X3, which will cause the modem to ignore dial tones (note, however, that X3 is  
not allowed in some countries, such as France and Spain).  
If the modem reports BUSY, the other number might be busy. Try again later.  
BUSY can also indicate that you failed to add a 9, prefix to the phone number if  
you must dial 9 for an outside line.

4 Troubleshooting  
If you must dial 9 to get an outside line, the easiest way to dial it automatically  
using legacy software is to include it in the modems dial prefix, e.g., ATDT9,.  
Note the comma, which inserts a pause before the number is dialed. By inserting  
9, into the dial prefix, you do not have to include it in each directory entry.  
To change the dial prefix in Windows HyperTerminal, select Connect from the  
Call menu, click Dialing Properties, and type 9 in the local and long distance  
boxes.  
If the modem reports NO ANSWER, the other system has failed to go off-hook, or  
you might have dialed a wrong number. Check the number.  
If the modem reports NO CARRIER, the phone was answered at the other end,  
but no connection was made. You might have dialed a wrong number, and a per-  
son answered instead of a computer, or you might have dialed the correct  
number but the other computer or software was turned off or faulty. Check the  
number and try again, or try calling another system to make sure your modem is  
working. Also, try calling the number on your telephone. If you hear harsh  
sounds, then there is a modem at the other end. In that case, the modems might  
be having problems negotiating because of incompatibilities or line noise. Try the  
call again, connecting at a lower speed by setting register S37 to a lower rate (for  
example, by typing ATS37=11 in the terminal window and pressing ENTER).  
Poor line conditions can also affect the connection. When using V.34 or V.32 cli-  
ent-to-client connections in poor conditions, setting S38=0 may result in better  
performance.  
The Modem Disconnects While Online  
If you have Call Waiting on the same phone line as your modem, it can interrupt  
your connection when someone tries to call you. If you have Call Waiting, dis-  
able it before each call. In most telephone areas in North America, you can  
disable Call Waiting by preceding the telephone number with *70 (but first check  
with your local telephone company).  
You can automatically disable Call Waiting by including the disabling code in  
the modems dial prefix (e.g., ATDT*70,note the comma, which inserts a pause  
before the number is dialed). For example, in Windows select Start | Settings |  
Control Panel, and then Modems. In the Modems Properties dialog box, select  
Multi-Tech MT5634ZPX-PCI, and then click Dialing Properties. Check This lo-  
cation has call waiting, and then select the correct code for your phone service.  
If you have extension phones on the same line as your modem, you or someone  
else can interrupt the connection by picking up another phone. If this is a fre-  
quent problem, disconnect the extension phones before using the modem, or  
install another phone line especially for the modem.  
Check that the phone cord between the modems LINE jack and the wall jack is  
undamaged and firmly connected to both.  
You might have had a poor connection because of line conditions or the problem  
might have originated on the other end of the line. Try again.  
Your ISP might have hung up on you because of lack of activity on your part or  
because you exceeded your time limit for the day. Try again.

The Modem Cannot Connect When Answering  
The default DTR Control command (&D2) inhibits autoanswer. To enable au-  
toanswer, change DTR Control to &D0, and make sure &Q0, &Q5, or &Q6 is  
also set. For more information, see the &D command in Chapter 4. For informa-  
tion on changing the modems default configuration, see Step 5: Install and  
Configure Your Softwarein Chapter 2.  
Autoanswer might be disabled. Turn on autoanswer in your communications  
program or send the command ATS0=1 (ATS0=2 if you have Caller ID service)  
to your modem in terminal mode.  
File Transfer Is Slower Than It Should Be  
If you are using a slow transfer protocol, such as Xmodem, try Zmodem or  
Ymodem/G instead.  
Is your line noisy? If there is static on your line, the modem has to resend many  
blocks of data to insure accuracy. You must have a clean line for maximum speed.  
If you are downloading a compressed file with MNP 5 hardware compression  
enabled, try disabling data compression. The transfer may be marginally slower  
with data compression enabled, because hardware data compression cannot  
compress a file already compressed by an archiving program.  
Does your Internet service provider (ISP) use the same 56K protocol as your mo-  
dem? The default setting of your modem is to connect using either the V.92 or  
the V.90 protocol, depending on which one the ISPs modem is using. If your ISP  
uses the V.90 protocol, the maximum speed you will be able to upload at is  
33,600 bps. Check with your ISP to see which protocols it supports.  
Are you trying to send a file to another client modem? If so, then your maximum  
possible connect speed is 33,600 bps. You can upload at speeds greater than 33,600  
bps only when connected to an ISP that supports the V.92 protocol.  
Try entering the I11 command in online mode or the &V command in command  
mode to display information about the last connection, making a screen print of  
the connection statistics, and checking for parameters that might be unacceptable.  
Data Is Being Lost  
If you are using data compression, set the serial port baud rate to two to six times  
the data rate.  
Make sure the flow control method you selected in your software matches the  
method selected in the modem (see AT commands &K and \Q.)  
Enter the I11 command in online mode or the &V command in command mode  
to display information about the last connection. Then make a screen print of the  
connection statistics, and look for unacceptable parameters.

4 Troubleshooting  
There Are Garbage Characters on the Monitor  
Your computer and the remote computer might be set to different word lengths,  
stop bits, or parities. If you have connected at 8-N-1, try changing to 7-E-1, or  
vice-versa, using your communication software.  
You might be experiencing line noise. Enable error correction, if it is disabled, or  
hang up and call again; you might get a better connection the second time.  
At speeds above 2400 bps, the remote modem might not use the same transmis-  
sion or error correction standards as your modem. Try connecting at a slower  
speed or disabling error correction. (With no error correction, however, line noise  
can cause garbage characters.)  
Enter the I11 command in online mode or the &V command in command mode  
to display information about the last connection. Then make a screen print of the  
connection statistics, and look for unacceptable parameters.  
The Modem Doesn’t Work with Caller ID  
Caller ID information is transmitted between the first and second rings, so if  
autoanswer is turned off (S0=0) or if the modem is set to answer after only one  
ring (S0=1), the modem will not receive Caller ID information. Check your ini-  
tialization string, and if necessary change it to set the modem to answer after the  
second ring (S0=2).  
Make sure that you have Caller ID service from your telephone company.  
Fax and Data Software Can’t Run at the Same Time  
Communication devices can be accessed by only one application at a time. Under  
DOS or Windows 3.1x, you can run either your fax software or your data com-  
munications software, but not both at the same time, unless you have a special  
communication device management application. In Windows 95 and higher, you  
can have data and fax communication applications open at the same time, but  
they cannot use the same modem at the same time.  
The Voice Functions Don’t Work  
There are several tests that you can perform to verify the voice circuits of the Multi-  
ModemZPX. First, make sure all connecting cablestelephone, microphone, and  
speakerare undamaged and firmly connected to the correct jacks. Then retry  
whatever action was not working. If the problem persists, try the voice mail test; if  
that doesnt work, and if you have a microphone and speaker connected to the  
MultiModemZPX, try the loopback and speakerphone tests, which do not require  
special software.

D Upgrading the Modem  
Appendix D - Upgrading the Modem  
Introduction  
Your modem is controlled by semi-permanent software, called firmware, which is stored in flash  
memory. Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off.  
However, it can be changed by either the manufacturer or the user as bugs are fixed or new features are  
added.  
Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few  
minutes by using the following procedures.  
Upgrade Overview  
The upgrade procedure consists of the following steps, which are described in greater detail in the  
following sections.  
1. Identify the model number and firmware version of your modem.  
2. Identify the current version of the firmware at the Multi-Tech Web site. If your  
modem already has the current firmware, there is no need to update it.  
3. Download the upgrade file and the appropriate Flash Wizard for your modem.  
4. Install the Flash Wizard and extract the firmware .HEX file from the file you  
downloaded.  
5. Document and clear your stored parameters.  
6. Upgrade the modems firmware using the .HEX file and the Flash Wizard.  
7. Restore your parameters.  
Step 1: Identify the Modem Firmware  
You must know the model number and firmware version of your Multi-Tech modem to know whether or  
not you should update it.  
1. Run your favorite terminal program. If you are using Windows 95 or above, you  
can use HyperTerminal.  
2. In the programs terminal window, type AT&F. Even if you cannot see the  
AT&F command on your screen, be sure to type it completely, and then press  
ENTER. If the modem does not respond with OK, repeat the AT&F command.  
3. Now type ATI, press ENTER, and record your results. The model number and  
firmware version should appear similar to that shown below.

D Upgrading the Modem  
Step 2: Identify the Current Firmware Version  
Identify the current version of your modems firmware at the Multi-Tech Web site. If your modem  
already has the current firmware, there is no need to update it.  
1. Using your favorite Web browser, go to http://www.multitech.com/SUP-  
2. Scroll down to your modem model number.  
3. Look at the firmware version number for your modem.  
4. If the firmware version number matches the firmware version number found in  
Step 1: Identify the Modem Firmware,your modem has the current firmware  
version, and does not need to be updated.  
5. If the firmware version number is greater than the firmware version number  
found in Step 1: Identify the Modem Firmware,your modem has an older  
firmware version. Continue with Step 3: Download the Upgrade File.”  
Warning: The first digit of the new firmware must match the first digit of the  
old firmware, or the modem may not work properly. E.g., if your current  
firmware version is 4.16, replace it only with 4.xx firmware, not 6.xx firmware.  
Step 3: Download the Upgrade File  
1. If you are not already at the MultiModemZPX Firmware page of the Multi-Tech  
Web site, follow the procedure in Step 2: Identify the Current Firmware.”  
2. Download the upgrade file for your modem by clicking its name, and save the  
file in a temporary folder on your hard disk.  
3. In the same section of the Web page, download the Flash Wizard utility by  
clicking it, and save it in the same folder. Alternately, install the Flash wizard  
from the MultiModemZPX compact disc.  
Step 4: Extract the Upgrade Files  
1. Install the Flash Wizard utility by double-clicking the Flash Wizard file name in  
Windows Explorer.  
2. Extract the upgrade files by double-clicking the file name. The extracted files in-  
clude a .HEX file, which contains the upgrade data, and a Readme file.  
3. Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default in-  
stallation, is at C:\Program Files\MultiTech Systems\Flash Wizard\.  
Step 5: Document and Clear Your Stored Paramenters  
Before you flash your modem, you should record the parameters that are currently stored in it so you  
can reprogram it after flashing. After you have recorded them, send the AT&W1Z command to the the  
modem to clear the stored parameters.  
1. Run your favorite terminal program.

D Upgrading the Modem  
2. In the programs terminal window, type AT&V and press ENTER to list your  
modems current parameters.  
3. Record your parameters by saving the screens and sending them to your printer.  
4. Type AT&W1Z and press ENTER to clear your stored parameters and reset your  
modem to factory default.  
5. Close the terminal program.  
Step 6: Upgrade the Modems Firmware  
Before you begin the following procedure, read the README.TXT file extracted from the upgrade  
archive file. Note the file name for the new firmware (example: ARQG125A.HEX). Also, if you are using  
Windows NT, you must disable Windows RAS and Microsoft Fax Service before upgrading the  
modems firmware. To disable RAS and your Fax service, Click Start | Settings | Control Panel, and  
then double-click Services. Select Remote Access Server , and then click the Startup button. Select  
Manual as the startup type, and then click OK. Do the same for any fax service.  
WARNING: Never install an older version of firmware over a newer version. Doing  
this WILL DESTROY THE FLASH PROM! If the flash PROM is destroyed, the mo-  
dem must be sent in for repair.  
1. Run Flash Wizard by double-clicking its icon or file name, or by selecting it  
from the Start menu. The program begins by identifying devices attached to  
your computer.  
2. Select the modem to be upgraded, and then click Next to proceed.  
3. Select the port to be upgraded from the Port list, select the appropriate .HEX file  
from the Hex File list, and then click Next to continue.  
Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.  
4. The Progress dialog box now displays the progress of the upgrade.  
Caution: Any disruption of the program during this stage of the upgrade can  
cause your modem to become inoperable. Wait for the Next button to become  
active before proceeding.  
5. When the flash upgrade is complete, the message Programming Complete  
appears. Click Next to continue.  
6. The Results dialog box appears next. Click Finish to exit Flash Wizard.  
Note: If you are using Windows NT, be certain to enable RAS and your fax ser-  
vice when the operating system restarts.  
Step 7: Restore Your Parameters  
Your modem has been updated. You can now open your terminal program to reprogram your modem  
parameters or to confirm the update by typing ATI in the terminal window and pressing ENTER.

E Installing Under Linux  
Note: The preceding example places the modem on COM3. Your IRQ and port  
may vary. Substitute the IRQ and port values in the example with the values for  
your computer as listed in the results of the command issued in step 3. To set  
Linux to configure the modem at boot-up, use an editor such as jedand add  
the setserial command to the end of the rc.local file.  
5. Once youve completed your installation, you must configure your modem for  
country-specific operation. See Chapter 2 for information on using AT com-  
mands to configure your modem for use in your country.  
Using the Terminal Program Minicom to Verify Operation  
This section describes how to make sure Linux can talk to the modem and be able to  
dial up to the Internet. Linux can use different programs and desktops depending on  
who made the Linux operating system and what version it is. The following proce-  
dures use the most commonly installed components of Red Hat 6.2. More informa-  
tion can be found in your Linux OS owners manual.  
1. At the command prompt, type minicom –s and press ENTER.  
2. Select Serial port setup and press ENTER.  
3. From Serial port setup, use the A key to access Serial Device, and then press  
ENTER.  
4. Press ESC.  
5. You are now in the Minicom terminal. Type AT and press ENTER. The screen  
should display OK to verify the operation. Alternately, dial a phone number to  
verify line operation  
6. To leave Minicom, press CTRL + A, and then press Z.  
7. On the help menu, press X to exit.  
Using the Modem to Call the Internet  
Linux allows different graphic user interfaces (GUI). In the following steps, well use  
the Gnome Desktop GUI and assume that the Internet Service Provider (ISP) you are  
calling assigns you the Domain Name Service (DNS) and Internet Protocol (IP) ad-  
dresses. For more information on DNS or IP, see the Linux OS owners manual or  
contact your ISP.  
1. On the Task Bar at the bottom of the screen, select the Gnome Footprint.  
2. Select Internet from the menu.  
3. Select Dialup Configuration Tool.  
4. Select Add, and then click Next.  
5. Enter the connection name and phone number, and then click Next.  
6. Enter your user name and password, and then click Next.

F Installing Under SCO OpenServer  
Appendix F - Installing Under SCO OpenServer  
Introduction  
This appendix explains how to install a modem on a computer operating under the  
SCO OpenServer 5.0.x operating system. Briefly, in SCO OpenServer , you do not  
need drivers for most modems. Programs in SCO OpenServer commonly call upon  
the port, rather than the modem.  
Installation  
Install the MultiModemZPX in the computer as described in Chapter 2.  
Setup  
1. Turn on the computer and allow the computer to boot to the command prompt.  
2. Log in as root.  
3. Determine the port address and IRQ for the modem by typing: hw -r pci  
To output the port address and IRQ information to a file, type: hw -r pci>pci.txt  
Caution: If you choose to output the information to a file, make sure the output  
file name includes the .txt extension. While logged on as root, the possibility  
exists that the system file pciwill be overwritten. By default, UNIX does not  
ask if you want to overwrite a file.  
4. Look at the ClassCode: 0x078000 (other communications device) section of the  
output. The MultiModemZPX is identified as SubSystemID: 0x0480.  
5. Use the first I/O address listed as the port address. In the output, look for:  
BaseAddr [x]: I/O NxNNNN  
where x is the first I/O base address (not memory) and NxNNN is the I/O address.  
6. Use Serial Manager (or mkdev serial) to add a serial port. Choose IBM Com X  
for the new port, where X is the number of the new port. Use the first I/O ad-  
dress listed in the output file created in step 3 (BaseAddr [x]:) as the port address.  
7. Use the IRQ listed in the InterruptLine of the output file created in step 3.  
8. Once the serial port has been added, the system will require the kernal to be  
relinked. After the relinking is complete, restart the system to activate the changes.  
9. Log back on as root.  
10. At this point, you may configure the modem as needed on the new port and add  
required entries to Devices.  
11. Once youve completed your hardware installation and system setup, you must  
configure your modem for country-specific operation. Refer to Chapter 2 for in-  
formation on using AT commands to configure the modem for use in your country.  
Note: If you are using the modem to dial out, a dialer may be needed.
