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 modem’s 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 computer’s 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 you’d like to reassign your
modem to COM3, type D:\COM-3\pcicom3.inf, where D: is the drive letter associated with your
computer’s CD-ROM drive. If you want to reassign your modem to COM4, type D:\COM-
4\pcicom4.inf and continue with the wizard’s instructions.
6. When the wizard completes its installation, your modem should be reassigned to the new COM port.

displays information about the modem’s COM port.
9. Write down the modem’s 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 modem’s 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

Step 4: Configure the Modem for Your Country
Before you use your modem, you must configure it for the country in which it will be used. You must
also do this if you move the modem to another country after it has been configured for the first country.
You can use one of two configuration methods: the Global Wizard utility or AT commands.
The Global Wizard Utility
The Global Wizard configuration utility is recommended for computers running Windows 95 or newer.
1. Insert the MultiModemZPX CD into the CD-ROM drive. The Autorun menu should appear.
2. Click Initial Setup and Country Selection.
3. In the Global Wizard dialog box, select either Run from CD or Install on your PC. Choose the
former to configure your modem without installing the Global Wizard on your computer. Choose the
latter to install the Global Wizard on you computer and Start menu.
4. Click Next. The Global Wizard searches for your modem and identifies it.
5. Click Next.
6. Select the country in which the modem will be used, and then click Next.
7. Review your choice of country. If it is correct, click Next to configure the modem.
8. When Global Wizard announces that the parameters have been set, click Finish to exit.
AT Commands
Non-Windows users can configure the modem using AT commands. You must enter these commands in
your communication program’s terminal window.
There is a separate document of AT Commands provided for reference on the MultiModem system CD.
1. Run your favorite communication program, and open the program’s terminal window.
2. To configure the modem for a specific country, type AT%T19,0,nn, where nn is the country code in
hexadecimal notation, and then press Enter.
3. To verify the change, type ATI9, and then press Enter. The country code is displayed in decimal
format.

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 modem’s 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 won’t 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 doesn’t work with Caller ID.
• Fax and data software can’t run at the same time.
• The voice functions don’t 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 don’t 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 software’s 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 modem’s 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.
17
MultiModemZPX User Guide
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 computer’s 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 device’s
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
modem’s initialization string, or in terminal mode enter ATV1X4 and press ENTER.
When you dial again, the modem reports the call’s progress.
•
If the modem reports NO DIALTONE, check that the modem’s telephone line
cable is connected to both the modem’s LINE jack (not the PHONE jack) and the
telephone wall jack. If the cable looks secure, try replacing it.
If that doesn’t work, the problem might be in your building’s telephone
installation. To test the building installation, plug a telephone into your modem’s
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 can’t, change your modem’s 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.
18
MultiModemZPX User Guide
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 modem’s 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 modem’s 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 modem’s 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 modem’s default configuration, see “Step 5: Install and
Configure Your Software” in 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 ISP’s 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.

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 cables—telephone, microphone, and
speaker—are 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 doesn’t 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.

Voice Mail Test
Test the MultiModemZPX’s voice function by using the included software to set up
the MultiModemZPX for voice mail. Have an acquaintance call and leave a message,
and then play it back.
If your modem does not play sound files in voice mode, go to Windows Control Panel
and double-click the Multimedia icon. Under the Audio tab, select Modem Wave
Driver as your preferred device for both playback and recording, then try again.
Loopback Test
1. Connect a microphone and speaker to the MultiModemZPX. To avoid feedback,
make sure the microphone and speaker are well separated; better yet, use a
headphone instead of a speaker.
2. Select Start, point to Programs, point to Accessories, and click HyperTerminal.
3. Click Cancel in the Connection Description dialog box.
4. In the HyperTerminal terminal window, type AT&&S and press ENTER. This
command causes input from the microphone to be looped back to the speaker.
5. Speak into the microphone; you should hear your voice on the speaker or head-
phone.
6. Type ATZ and press ENTER to reset the modem.
Speakerphone Test (with voice option)
1. Connect a microphone and speaker to the MultiModemZPX.
2. Select Start, point to Programs, point to Accessories, and click HyperTerminal.
3. Click Cancel in the Connection Description dialog box.
4. In the HyperTerminal terminal window, type

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 modem’s 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 program’s 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 modem’s firmware at the Multi-Tech Web site. If your modem
already has the current firmware, there is no need to update it.
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
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.
34
MultiModemZPX User Guide
D Upgrading the Modem
2. In the program’s terminal window, type AT&V and press ENTER to list your
modem’s 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 Modem’s 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
modem’s 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.

Appendix E - Installing Under Linux
Introduction
This appendix explains how to install a modem on a computer operating under the
Red Hat Linux 6.2 operating system. Other versions of Red Hat and other Linux op-
erating systems should be similar. Briefly, in Linux, you do not need drivers for most
modems. Programs in Linux commonly call upon the port, rather than the modem.

Installation
Setup
Install the MultiModemZPX in the computer as described in Chapter 2.
1. Turn on the computer and allow the computer to boot to the command prompt.
2. Log on as root.
3. Determine the resources the modem is using by typing the command cat /proc/pci
or the command less /proc/pci. Look for the entry listing vendor id=11c1 and
device id=480. Note the IRQ the device uses as well as the first I/O address listed.
Output example:
Non-prefetchable 32 bit memory at 0x00000000
Bus 0, device 17, function 0:
Communication controller:Unknown vendor Unknown device (rev 0)
Vendor id=11c1 Device id=480
Medium devsel. Fast back-to-back capable. IRQ 11. Master
Capable. No bursts.
Min GNT=252. Max lat=14
Non-prefetchable 32 bit memory at 0xe4000000
I/O at 0x6400
I/O at 0x6800
I/O at 0x6c00
4. Using the IRQ and first I/O address from the output obtained in step 3, type the
command setserial /dev/ttySx uart 16550A port y irq z, where x is the serial de-
vice you want to use, y is the I/O address, and z is the IRQ. Example: setserial /
dev/ttyS2 uart 16550A port 0x6400 irq 11.
36
MultiModemZPX User Guide
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 “jed” and add
the setserial command to the end of the rc.local file.
5. Once you’ve 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 owner’s 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, we’ll 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 owner’s 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.
7. Select Normal ISP if your ISP is not listed, and then click Next.
8. Click Finish.

Calling the ISP
1. On the Task Bar at the bottom of the screen, select the Gnome Footprint.
2. Select Internet from the menu.
3. Select RH PPP Dialer.
4. Select the connection name you entered in step 5 of the previous section.
5. Click OK.
Answering Calls
To use the system for answering calls, Linux requires other programs to be installed,
such as Mgetty, Mgetty+Sendfax, and others, depending on your requirements. Each
vendor of Linux has more than adequate information on installing these programs.

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 “pci” will 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 you’ve 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.
