Sound Card Considerations
If you want speakerphone functions along with the ability to
record sound or .WAV files through the sound card at the same
time, you need:
• two stereo PC microphones
• one stereo male-to-male patch cord
• one sound card and optional speakers
To connect a 3rd party sound card, perform the following steps:
1. Obtain a stereo male-to-male patch cord (can be purchased
at a local PC retail store).
2. Place one end of a stereo male-to-male patch cord into the
“LINE OUT” jack of the MultiModemZPW-PCI and the other
end into the “LINE IN “ jack of the sound card. This lets you
to hear the activity of the modem whether it is originating or
answering a call or playing a recorded message using the
bundled Trio software.
3. Place the two stereo microphones (do not use mono
microphones) far enough apart from each other to eliminate
feedback (e.g., one on each side of the monitor). Feedback
will only occur if the microphones are too close to each
other. Make sure speakers are amplified with power source
being either a battery or AC outlet.
4. Place the microphone and speakers far enough apart from
each other to eliminate feedback. Plug the connector of
both microphones into the “MIC IN” jack of both the
SoundCard and the MultiModemZPW-PCI.

Operating Your MultiModemZPW-PCI
You control your MultiModemZPW-PCI by issuing AT
commands and setting S-Registers. Right now your
MultiModemZPW-PCI is set up for the most typical user
application, that is, as a traditional modem set to make a dial-up
call to a remote installation where the call is answered
automatically; therefore, you shouldn’t need to change the
current default configuration. (If however, you know that your
application does not follow this profile, please refer to Chapter 3
for AT Commands and S-Registers.)
In operating your MultiModemZPW-PCI it is likely that you will
use your data communications software to either:
• enter “terminal” mode, where you can “speak most directly”
to the modem by issuing AT commands, or to
• launch a datacomm session through a set of modem
configurations which you select and then associate with a
target telephone number. Once you have created, saved,
and named this set of information according to your
connection needs and your datacomm software’s
conventions, the software then simplifies your dialing
because you needn’t reconfigure your modem, nor run the
risk of mistakenly keying-in incorrect information.
Either way, you need to understand that an AT command is the
method by which your modem is controlled, and must therefore
prefix nearly all commands. AT stands for attention, and alerts
the modem that a command follows. You may enter these
commands with either upper- or lower-case characters. Once
you’re in terminal mode, enter AT followed by <CR> to check
whether your modem is operational. If everything’s fine, your
modem will respond OK.
24
MT5634ZPW-PCI
Page 25
2 Installation
Simple Operations
You can dial by using the ATD command and the phone number
of the modem with which you wish to connect, e.g.,
ATD6127853500. Your modem will dial the number; a
“scrambling” noise is heard as the modem negotiates the kind of
connection it can make, and once the modems have settled on a
common connection, a connect message on your computer’s
video is displayed. To hang up a call, enter +++ATH<CR>.
Your modem will return on hook. Your video now displays OK,
signifying that your modem is ready for your next command.
Software Configuration
Communications software must be configured to work with the
MultiModemZPW-PCI, your computer, and the remote system it
is calling. Fortunately, most communications programs make
the process easy by providing a default initialization string to
your modem as well as defaults for most of the other required
parameters. Some software programs allow you to select your
modem type from a menu. By this method, initialization strings
that correspond to a particular modem type can be selected to
operate optimally with the software it is utilizing.
*: Refer to your respective software manual for further
information on your communications software.
Other software programs require you enter an initialization string
in the software modem setup screen. If this is the requirement in
your software application, enter the following command string to
initialize your modem:

Testing the MultiModemZPW-PCI’s Voice
Function
There are several tests you can perform to verify the
MultiModemZPW-PCI’s voice circuits. Try the answering machine
test first; if that doesn’t work, and you have a microphone and
speaker connected to the MultiModemZPW-PCI, try the
loopback and speakerphone tests, which can test the modem’s
voice circuits without special software.
MultiModemZPW-PCI’ s Answering Machine
Test
Test the MultiModemZPW-PCI’s voice function by using the

Introduction
Communications software must be customized, or
make it work with your computer’s serial port and modem, to
meet the requirements of the system on the other end of a
connection, and to meet your own requirements.
Windows 95® makes configuration easy for Windows 95–
compliant communications software. The modem and port are,
for the most part, configured automatically when the modem’s
drivers are installed in Windows. The communications software
then uses the Windows 95–supplied configuration when it dials
out.
This chapter will help you make configuration choices specific to the
MultiModemZPW-PCI. For help with other configuration choices,
please refer to the software’s manual or online Help. Generally,
your best course is to accept the software’s default values.
configured
Configuring Communications Software
1. Turn on your computer and run your communications
software.
2. Find the dialog box or menu that lets you specify your
modem. (In HyperTerminal, select File, Properties, Phone
Number; in ProComm Plus for Windows, select Window,
Setup, Advanced; and in MultiExpress Terminal for
Windows, select Setup, Terminal, Modem.)
, to
3. If you are using legacy software, or if you have more than
one modem installed, choose the appropriate model number
for the MultiModemZPW-PCI (e.g., Multi-Tech MT5634ZPWPCI ) from the software’s modem list. If your model number
isn’t listed, choose a generic modem of the same speed as
yours, i.e., a generic V.34 or 33600 bps modem, and
rename it “Multi-Tech MT5634ZPW-PCI”.
34
MT5634ZPW-PCI
Page 35
3 AT Commands, S-Registers and Result Codes
4. If your legacy software doesn’t have the correct modem
initialization string, you must change it. AT&F^M, which
selects the modem’s factory default settings, works well for
most connections. (^M is the code for the carriage return
character that sends the string to the modem.) If you need
extra time to make a connection, add S7=60 to the string,
like this: AT&FS7=60^M. For CompuServe, the initialization
string should be AT&F\N0^M. If you use CompuServe’s
WinCIM software, change the initialization string to
AT&F\N0\Q1^M for compatibility with WinCIM’s software
flow control. Change the error correction string to \N7%C0,
and the data compression string to \N7%C1. If you want the
modem to always answer the phone, add S0=1 to the
initialization string.
*: To change the modem’s default initialization string, type the new
commands in the software’s terminal window, adding the command
&W
to store the new commands in the modem’s nonvolatile memory;
e.g., AT&FS0=1&W. You can then simplify your initialization string to
ATZ^M.
5. If you are using legacy software, select the port the modem
is connected to (normally, COM3).
6. For maximum throughput when using data compression, set
the serial port baud rate, or DTE rate, to 115,200 bps. (In
Windows 95, select Start, Settings, Control Panel, Modems,
Properties.)
7. If your legacy software has an autobaud selection, make
sure it is disabled. Autobaud is for much older modems, and
can cause problems if enabled.
8. If the software allows you to edit the no-connect messages
(
NO CARRIER, BUSY, NO ANSWER, NO DIALTONE
make sure there is no space between
NO DIALTONE
MT5634ZPW-PCI
.
DIAL
and
TONE
),
in
35
Page 36
Owner’s Manual
9. If you must dial 9 to get an outside line, edit the dialing prefix
to include a 9 and a comma, e.g., ATDT9, (the comma
inserts a pause before dialing the next digit). Similarly, to
turn off call waiting for the duration of the call, insert the
disabling code used in your area, e.g., ATDT*70,. If you are
using Windows 95-compliant software, make these changes
in the “How I dial from this location” box of the Dialing
Properties sheet.
*: *70 is only used in the United States.

AT Commands
This section summarizes your modem’s AT commands. For detailed
information on the commands, download ZPW-PCIHELP.EXE from
the Multi-Tech BBS (see “Call the Multi-Tech BBS” in Chapter 3).
Note: Some dialing and answering defaults and restrictions may
vary for international modems. Changing settings may cause a
modem to become non-compliant in specific countries. Also note
that some software packages may have features, or lack restrictions,
that may cause the modem to become non-compliant.

Introduction
This chapter covers some common problems you may run into
with your modem and how to solve them. Your
MultiModemZPW-PCI 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. Always begin with the initial checklist to
make sure all hardware is properly connected. Then review the
common problems for recommendations on what to change.
Initial Checklist
Always begin with the following checklist to make sure all
hardware is properly connected and that the modem is set up
properly.
• Make sure you are running the Microsoft Windows 95
operating system. This modem will not run properly with
other operating systems.
• Make sure the COM port you chose during setup matches
the COM port set in your communications software. See
Chapters 2 and 3.
• Check that the phone cord between the modem’s “LINE”
jack and the wall jack is undamaged and firmly connected to
both.
• If you connected a telephone to your modem, check that the
phone cord between the modem’s “PHONE” jack and the
telephone is undamaged and firmly connected to both.
• If you connected a microphone to your modem, check the
connection of the microphone plug to the modem’s “MIC IN”
jack.
• If you connected speakers to your modem, check the
connection of the speaker plug to the modem’s “LINE OUT”
jack.

• Retry whatever action was not working.
• If it still does not work, check the following section for a
description and possible solution of your problem.
• If you do not find your problem listed in the next section, see
Chapter 7 for information on how to reach one of our
technical support technicians via our toll-free telephone
number, the Internet, or CompuServe. Don’t forget to fill out
the information in “Recording Modem Information” in
Chapter 7 before contacting a technical support technician.
Common Problems
You may encounter the following problems:
• The modem does not respond to commands.
• The modem dials but is unable to make a connection.
• The modem disconnects while online.
• The modem cannot connect when answering.
• File transfer appears slower than it should be.
• Data is being lost.
• There are garbage characters on the monitor.
• Fax and communications software won’t run at the same
time.
If you experience problems, please check the following
possibilities before calling Technical Support (see Chapter 7).
MT5634ZPW-PCI

Owner’s Manual
The Modem Does Not Respond to Commands
• Make sure you are in terminal mode in your data
communications program, then type AT and press ENTER.
If you get an OK response, your connections are good and
the problem likely is in the connection description in your
communications software.
• Try resetting your modem by sending it an
command in terminal mode. If you are using legacy
software— software designed for an older operating
system—make sure the initialization string includes &F as
the first command, to cancel any “leftover” commands that
could interfere with the modem’s operation.
• If you don’t get an OK, the problem may still be in the
communications software. Make sure you have done
whatever is necessary in your software to make a port
connection. Most legacy communications programs connect
to the COM port when the software loads, and remain
connected until the program terminates. Some, however,
can disconnect without exiting the program; if you have one
of these, try issuing the software’s connection command.
Also, if more than one communications program is open,
they can conflict with each other. Make sure all other
communications programs are closed, and then try again.
• If you are using legacy software, its COM port setting may
not match the COM port Windows 95 assigned to the
modem. Compare the COM port setting in your software to
the COM port reported in the Diagnostics tab of the Modems
Properties sheet. (Select Start, Settings, Control Panel,
Modems, Diagnostics.)
• Another expansion card, such as a bus mouse or sound
card, might be using the same COM port, memory address,
or interrupt request (IRQ) as your modem. On the Windows
95 desktop, right-click on My Computer, select Properties,
Device Manager, and Ports, then double-click on the
ATZ
or
AT&F

Communications Port your modem is connected to. In the
port’s Properties sheet, click on the Resources tab to see
the port’s Input/Output range and Interrupt Request. If
another device is using the same address range or IRQ, it
will appear in the Conflicting Device List. Uncheck Use
Automatic Settings to change the port’s settings so they do
not conflict with the other device, or select the port the
conflicting device is on and change it instead. If you need to
change switches or jumpers on the conflicting device; refer
to the device’s documentation.
• The modem may be defective. If you have another
MultiModemZPW-PCI, try swapping modems. If the problem
goes away, the first modem is possibly defective. Call
Technical Support for assistance (see Chapter 7).

The Modem Dials But Cannot Make a Connection
There can be several reasons the MultiModemZPW-PCI fails to
make a connection. Possibilities 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.
You can narrow the list of possibilities by using extended result
codes. If you have disabled the modem’s extended result codes,
re-enable them by entering ATV1X4 in the terminal window and
pressing ENTER. When you dial again, the modem will report
the call’s progress.
• If the modem reports
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 may 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 may be
installed behind a company phone system (PBX) with an
internal dial tone that sounds different from the normal dial
tone. In that case, the modem may not recognize the dial
tone and may treat it as an error. Check your PBX manual to
see if you can change the internal dial tone; if you can’t,
change your modem’s initialization string to include 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 may be busy,
in which case you should try again later, or it may indicate
that you have failed to add a 9, prefix to the phone number if
you must dial 9 for an outside line.
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. For
example, to change the dial prefix in MultiExpress Terminal,
select Setup, Modem; then select the modem type you are
using and type the new prefix in the Dial Prefix box. To
change it for Windows 95 software, select Start, Settings,
Control Panel, Modems. In the Modems Properties sheet,
select the appropriate MultiModemZPW-PCI model number
(e.g., Multi-Tech MT5634ZPW-PCI), click Dialing Properties,
and type 9 in the local and long distance boxes in the “How I
dial from this location” box.
• If the modem reports
NO ANSWER
, the other system has
failed to answer, 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 person
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 another modem is answering the call,
and the modems may be having problems negotiating
because of modem incompatibilities or line noise. Try
connecting at a lower speed by setting register S37 to a
lower rate (e.g., by typing ATS37=11 in the terminal window
and pressing ENTER) and then calling again.

The Modem Disconnects While Online
• If you have call waiting on the same phone line as your
modem, it may interrupt your connection when someone
tries to call you. If you have call waiting, disable it before
each call. In most telephone areas in North America, you
can disable call waiting by preceding the telephone number
with *70 (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 telephone
number is dialed). For example, to change the dial prefix in
MultiExpress Terminal, select Setup, Modem; then select
the modem type you are using, and type the new prefix in
the Dial Prefix box. To change it for Windows 95 software,
select Start, Settings, Control Panel, Modems. In the
Modems Properties sheet, select the Multi-Tech
MT5634ZPW-PCI, click Dialing Properties, check “This
location has call waiting,” and select the correct code for
your phone service.
Note: *70 is only used in the United States.
• 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 frequent problem,
disconnect the extension phones before using the modem,
or install another phone line especially for the modem.
• Check for loose connections between the modem and the
telephone jack.
• You may have a poor connection because of line conditions
or the problem may have originated on the other end of the
line. Try again.
• If you were online with a BBS or a commercial online
service, it may 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.

4 Troubleshooting
The Modem Cannot Connect When Answering
• Auto-answer may be disabled. Turn on auto-answer in your
data communications program or send the command
ATS0=1
to your modem in terminal mode.
File Transfer Appears Slower Than It Should Be
• If you are using a slow transfer protocol, such as Xmodem
or Kermit, 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.
• Are you downloading a compressed file with MNP 5
hardware compression enabled? Since hardware data
compression cannot compress a file already compressed by
an archiving program, the transfer can be marginally slower
with data compression enabled than with it disabled.
Data Is Being Lost
• If you are using data compression, be sure the serial port
baud rate is set to a minimum of four times the data rate.
• Make sure the flow control method you selected in software
matches the method selected in the modem. If you are using
CompuServe’s WinCIM software, you must set the modem
for XON/OFF flow control (see Chapter 4 for the
CompuServe initialization string).
• Try entering the &V (View Parameters) command, making a
screen print of the diagnostics listing, and checking for
parameters that may be unacceptable.
MT5634ZPW-PCI
63
Page 64
Owner’s Manual
There Are Garbage Characters on the Monitor
• Your computer and the remote computer may 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 communications software.
• You may be experiencing line noise. Enable error correction,
if it is disabled, or hang up and call again; you may get a
better connection.
• At speeds above 2400 bps, the remote modem might not
use the same transmission 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.)
• Try entering the &V (View Parameters) command, making a
screen print of the diagnostics listing, and checking for
parameters that may be unacceptable.
Fax and Data Software Won’t Run at the
Same Time
• Although you can have Windows 95-compliant data and fax
communication applications open at the same time, they
cannot use the same modem at the same time. Make sure
no other application is online when you try to dial out. If you
are using legacy communications software with Windows 95,
you may get a message that another application is
occupying the device even when no call is in progress.
Close any open legacy communications programs, and try
again.

result in the devices not ringing in response to an incoming
call. In most, but not all areas, the sum of the REN’s should
not exceed five (5.0). To be certain of the number of devices
that may be connected to the line, as determined by the total
REN’s, contact the telephone company to determine the
maximum REN for the calling area.
4. If this equipment causes harm to the telephone network, the
telephone company will notify you in advance that temporary
discontinuance of service may be required. But if advance
notice isn’t practical, the telephone company will notify the
