The modem
A modular telephone cable to connect your modem to the telephone line
Power adapter
This installation guide and user's manual
Communication software and manual (option)
You will also need an available RS-232 serial port on the personal computer and a
properly configured RS-232C interface cable.
Microphone (option)
Stereo audio cable (option)
A driver disk for Windows 95, Windows NT3.51, Windows NT 4.0
When you open your package, make sure all of the above items are included and not
damaged. If you see that any components are damaged, please notify your dealer
immediately.
1.2 What else you need
To complete your data communication system, you will need the following items:
Some type of communication software, if not included.
An optional telephone set ( you do not need to use a telephone with your modem ).
1.3 Installing the modem
Your modem fits neatly under most standard desk-top telephone. You should place your
modem near a 110 or 220 VAC power source (such as a wall outlet). The distance
between the modem and your computer, terminal, or printer is determined by the length of
your RS-232-C cable.
Be sure you can clearly see the panel LEDs, reach the ON/OFF switch on the back panel,
and hear the built-in speaker when you dial calls or the speakerphone is in use.
1.4 Prerequisites
When connecting your modem to a computer, you will need:
An available RS-232-C serial port.
5634RCS User’s Manual
An RS-232-C cable with at least one male connector for connecting to your modem;
Your computer's requirements determine the gender of the connector on the other end.
Software that lets the modem communicates with your computer.
If you lack any of these items, refer to your computer reference manual or contact your
computer dealer. If your computer does not have an RS-232C DB25 connector, obtain an
adapter cable from your computer dealer.
1.5 Connecting to a computer or terminal
Use the following procedure to connect your modem to a computer or terminal.
1. Plug the male DB-25 connector on your RS-232C cable into the RS-232 connector on

your equipment or contact your computer dealer.
3. After making the connection, check your computer or terminal requirements for the
Carrier Detect and Data Terminal Ready signals. The &C command affects the Carrier
Detect signal, and &D command affects the Data Terminal Ready signal. Refer to
Chapter 5 List of modem commands.
1.6 Connecting to the telephone line
Use the following procedure to connect your modem to the telephone line:
1. Make sure you have an RJ-11 telephone jack. If you need a modular jack, either obtain
a telephone adapter from a telephone or electronics store and follow the installation
instructions provided with the adapter, or have your local telephone company replace
your existing telephone jack with a modular-type jack and your existing telephone cord
with a modular cord.
2. Unplug your telephone's cable from the wall jack.
3. Take one end of the modular telephone cable supplied with your modem and plug into
the LINE jack on the back of the modem (see Figure 1-1).
4. Plug the other end of the telephone cord into the telephone jack on the wall.
5634RCS User’s Manual
1.7 Connecting to your telephone
Your modem is so convenient. It provides a second modular telephone jack that lets you
connect your telephone to the same telephone line the modem is using. This lets you
manually dial data calls or make voice calls when you are not using your modem.
Use the following procedure to connect your telephone to your modem:
1.
2.
Connect the telephone's modular cord into the PHONE jack on the back of your
modem (see figure 1-1).
Lift your telephone's handset and listen for a dial tone.
1.8 Connecting to an AC outlet
Use the following procedure to connect your modem to an AC outlet:
1. Insert the supplied power cable into the round AC-IN connector next to the POWER
switch on the back of the modem (see figure 1-1).
2. Plug the end with the power pack into either a 110 or 220 VAC outlet.
3. Turn the POWER switch to ON position, then the MR LED goes on.
4. Turn on the computer or terminal connected to the modem.
1.9 Using a external MIC and speaker1
If you want to use an external MIC or speaker instead of using the built-in speaker, you
need to insert your external MIC or speaker cable into the round MIC or speaker

Figure 1-3. Completed modem installation
If you connected the modem to a computer, place the computer into terminal mode and
complete the configuration information required by the software. Refer to your software
manual to find out which commands to use.
Then use the following procedure to verify your modem connections:
1. Type AT and press the Enter key. The RD and TD LEDs flash on the modem front
panel. If your system is operating properly, your modem sends an OK response to your
computer screen and wait for your next command.
If the LEDs did not FLASH, or if you did not receive a response, make sure your computer
is sending commands to your modem at a speed of 300, 1200, 2400, 9600, 19200, 38400,
57600 or 115200bps. If this does not solve your problem, contact your computer dealer.
2. Use your communication software to prepare your computer to dial a call. Then type
ATD x phone number, where x is either T for Touch-Tone dialing or P for Pulse dialing
and phone number is the telephone number that your modem is using
For example, if your modem is connected to the telephone line 555-2121 and Touch-Tone
dialing is supported in your calling area, type ATDT 555 2121
3. Press the Enter key. You should receive a BUSY response and you should hear the
busy signal through the modem speaker because the modem is calling itself.
Your modem is now ready for operation. Refer to the manual that came with your
communication software to begin communication. If you will be communicating directly
with your modem, or if you want to find out more about the modem's operation, proceed to
use's manual.
5634RCS User’s Manual
If you want to turn off your modem, set the POWER switch on the back of the modem
to the OFF position.

Chapter 2 Typing commands and receiving responses
Chapter 2 describes the format to use when typing modem commands. Chapter 2 also
describes the responses that your modem sends to your computer screen when you
execute, or try to execute, modem commands.
If you will be using a communication software program to make data calls, you will
probably not need to type commands, because your software program will handle these
tasks for you. Similarly, you will probably not see the responses because your software
program may intercept them.
However, if you perform data activities directly with your modem, you will find the format
for typing modem commands and modem response helpful.
2.1 Typing a command
Using commands, you can have your modem perform a variety of activities, such as
dialing or answering a data call or sending a fax. In order to send commands to your
modem, You must type a command line while your modem is in command mode.
2.2 To type a command line
1. Type AT. These characters must precede every command line. (except when you type
the A/ command, described on page 31)
2. Type the commands you want your modem to execute. A command line can contain
up to 40 characters.
3. Press the Enter key. The modem will then execute the commands on the command
line.
2.3 Correcting a typing mistake
If you make a mistake while typing a command, press the Backspace key to delete the
error. You can delete every command except AT.
2.4 Readability
To make a command line easy to read, you can insert spaces parentheses, hyphens, and
other punctuation in your command line. For example:
AT M3 DT 9, 1(818)555-1234
Your modem ignores spaces and punctuation when executing a command line, but these
characters apply to the 40 characters limit.
10
5634RCS User’s Manual
2.5 Typing more than 40 characters
If you want to type more than 40 characters on a command line, type a regular command
line (up to 40 characters long) and end it with a semicolon as the last character. When
you press Enter, your modem executes the commands and returns to command mode, so
you can type your next command line.
2.6 Omitting a parameter
Some commands require a numeric parameter such as 0,1, or 2. For example, the Q
command determines whether your modem sends a modem response after executing a
modem command line:
Q0 tells the modem to send responses.
Q1 tells the modem not to send response.
If you type ATQ and press the Enter key without typing a parameter of 0 or 1 after the Q,
it's like typing Q0 and the modem will send modem responses.
2.7 Repeating a command line
For your convenience, the last command line you execute remains stored in the modem's
memory until you type a new command line and press the Enter key. If you want to reexecute the last command, type A/.
When you want to use the A/ command, you don't need to preface it with the AT
characters or end it by pressing the Enter key. Just type A/ to have your modem
automatically re execute the last command line.
The A/ command is particularly useful when you want your modem to re-execute a lengthy
command line or redial a number that was busy.
You can continue using A/ to automatically re-execute the last command line until you
type a new command line that begins with AT or reset your modem, or until your modem
loses power.
2.8 Modem responses
When you send a command to your modem, it sends a response to your computer. For
example, if you send a modem command to your modem, the modem should respond with
OK. You may never see these responses, however because certain communication
software will intercept them before they can be displayed on your computer screen.
This section describes the modem responses returned by the modem when you
communicate directly with the modem. If you will be using a communication software
11
5634RCS User’s Manual
program to make data calls, you may not see these responses because your software
program will probably intercept the responses.
Response sets
Modem responses can come from one of five response sets. These response sets are
designed X0, X1, X2, X3, and X4.
The response sets determine which modem responses are sent by the modem. They also
define certain dialing characteristics and how the modem handles dial tones and busy
signals, as described in the following sections.
2.9 Word or numeric responses
Modem responses can appear as words or numbers. Your modem is set up to return word
responses. Word responses are followed by a carriage return and line feed.
If your modem is operating under an application that handles character strings inefficiently
or cannot handle them at all, you can use the V0 command to switch to numeric modem
responses. Numeric responses are followed by a carriage return only.
If you do not want to receive modem responses at all, you can use Q1 command to
disable them. You may want to disable responses entirely if your modem is connected to a
printer and you do not want the modem responses printed.
2.9.1 X0 response set
The X0 response set consists of the first five responses in Table 2-1. with this response
set, you receive the CONNECT response for all connections, regardless of the speed at
which they're made.
When you send a Dial command line with this response set in effect, the modem will wait
two seconds after receiving your Dial command, then automatically dial the telephone
number whether or not a dial tone is present This is known as "blind dialing." You may
want to use blind dialing if you will be using the modem in an area that has an irregular or
weak dial tone that your modem cannot always detect.
2.9.2 X1 response set
The X1 response set consists of the all responses in Table 2-1, except NO DIALTONE,
BUSY and NO ANSWER. When you send a Dial command with this response set in effect,
your modem will blind dial call.
2.9.3 X2 response set
The X2 response set consists of all responses in Table 2-1, except BUSY and NO
ANSWER.
12
5634RCS User’s Manual
When you send a Dial command with this response set in effect, your modem will listen
for a dial tone before dialing. If it does not detect a dial tone within five seconds, it hangs
up and returns the NO DIALTONE response.
2.9.4 X3 response set
The X3 response set consists of all responses in Table 2-1, except NO DIALTONE.
When this response set is in effect and you send a Dial command to your modem, your
modem will blind dial the call. If the telephone number dialed is busy, your modem will
send the BUSY response.
2.9.5 X4 response set
The X4 response set is the factory-default response set. It consists of the all responses in
Table 2-1. This response set allows the modem to detect a dial tone and also a busy
signal.
2.10 Correction & compression responses
If your modem supports the MNP and V.42/V.42bis error-correction and data-compression
protocols, you can use the Wn command to enable the extended responses shown in
Table 2-1.
The W command that enables negotiation progress responses is not the same
command as the W dialing modifier used in dial command lines.
The default setting, W0, disables extended responses. With W0, all CONNECT responses
report the DTE speed.
To receive the CARRIER and PROTOCOL responses in Table 2-1, send the W1
command. When this command is in effect, the CONNECT response will show the DTE
speed.
If you want the CONNECT response to show the DCE speed rather than the DTE speed,
send W2 command. With this command, extended responses will be disabled.
Modems that support the MNP and V.42/V.42bis error-correction and data-compression
protocol can also use the \V1 command to append /ARQ to the end of all CONNECT
responses when your modem makes an error-correction data connection with a remote
modem.
If you do not want /ARQ appended to the end of CONNECT responses when an errorcorrection data connection is made, send the \V0 command.

Chapter 3 Using configuration profiles
Your modem is preset so that you can begin transferring data files as soon as you install
the modem and load your communication software.
If you dialing and answering requirements do not match the modem's default configuration
profile, you can create your own profiles and store them safely in your modem's
nonvolatile memory. The profiles will be saved, even when you turn off your modem.
When you need to use a certain profile, send the appropriate command.
You can save two custom configuration profiles in your modem's nonvolatile memory. You
save profiles using &Wn command. The n can be the number 0 or 1, which corresponds
to the location in nonvolatile memory where you want the profile stored.
Using the &Wn command, you can store the following commands (refer to Chapter 5 for
description of these commands):
B1, T, E1, F0, L2, M1, Q0, V1, X4, Y0, &C0, &D0, &G0, &J0, &K3, &L0, &P0, \A3, \B2,
%C1, \N3 .........
You can also store the following register values
these registers):
(refer to Chapter 6 for a description of
S0=0, S2=43, S6=2, S7=30, S8=2, S9=6, S10=14, S11=95, S12=50, S18=0, S25=5 ...
3.1 Storing a profile
The following example shows how you can store a profile. Assume that you want to save
the following commands in profile 0:
X1
E0
&C1
&D0
&M0
S0=3
To do so :
1. Type AT
2. Type the commands shown above
3. Type the &W0 command as the last command on the command line to save these
commands as user Profile 0.
4. Press the Enter key. This custom configuration profile is now saved under user Profile
0.
3.2 Recalling a profile
After you store a custom configuration profile, you can recall it using the AT&Yn
command. For example, to recall profile 0 :
Type AT&Y0
19
5634RCS User’s Manual
1. Press the Enter key. The next time you turn on or reset your modem, it will drive its
operating characteristics from Profile 0.
2. To recall Profile 1 instead of Profile 0, type AT&Y1 instead of AT&Y0.
3.3 Reset and recalling profile
If you prefer, you can use ATZn command to reset the modem and load a stored
configuration profile : For example, to reset your modem and recall Profile 0 :
1.
2.
Type ATZ0
Press the Enter key.
Returning to the default profile
1. To return to the factory default profile 0:
2. Type AT&F0
Press the Enter key. Your modem returns to basic asynchronous operation, which is the
profile in effect when you received your modem. The following table lists the modem's
default profile.

Chapter 4 Error correction and data compression
Your modem supports sophisticated MNP 1- 4 and V.42 error- correcting protocols. These
protocols ensure the transmission of error-free data − even over noisy, error- prone
telephone lines. Your modem also supports the V.42bis and MNP 5 data-compression
protocols, which maximizes data throughput and significantly reduces the time needed to
exchange data.
4.1 Error-correction protocols
Your modem includes two error-correction protocols:
MNP level 1 through 4
CCITT V.42
When these protocols are used, the two modems perform calculations on each "packet" of
data being exchanged and compare their values. If the values do not match, the receiving
modem requests the sending modem to re transmit the packet.
MNP is an acronym for Microcom Networking Protocol. MNP detects and corrects errors
that occur when data is exchanged between two systems. Errors can result from
telephone- line noise and other signal distortions.
4.2 V.42
V.42bis the accepted international standard for error correction, ratified by ITU-T in
January 1990. It is generally felt that the handshake and protocol establishment process
of V.42 is superior to that MNP 4. Therefore, it will provide better initial connections on
poor quality telephone lines.
Moreover, while the effective data speed of V.42 and MNP 4 are almost identical over
noise-free telephone lines, V.42 provides significantly better performance than the ITU-Tspecified MNP4 over noisy telephone lines.
4.3 Configuring for auto-reliable operation
Auto-reliable operation is the modem's default configuration, so if you haven't given the
modem any \N commands, it should already be in auto-reliable mode.
Auto-reliable mode lets your modem communicate with both MNP/V.42/V.42bis modems
and modems that do not use MNP/V.42/V.42bis :
1. Type AT\N3%C3 (Factory Setting)
2. Press the Enter key. Your modem responds with OK. When your modem originates or
answers calls, it will try to make a V.42bis/V.42 connection. If either or both fail, your
modem will try to make an MNP connection. If that fails, your modem will try to make a
normal connection that does not use error correction.
22
5634RCS User’s Manual
4.4 Configuring for reliable operation
To communicate with remote MNP modems only:
1. Type AT\N5
2. Press the Enter key. Your modem responds with OK. When your modem originates or
answers calls, it will try to make an MNP connection. If that fails, your modem will
hang up and return to command mode.
To communicate with remote V.42 modems only:
1. Type AT\N4
2. Press the Enter key. Your modem responds with OK. When your modem originates or
answers calls, it will try to make a V.42/V.42bis connection. If that fails, your modem
will hang up and return to command mode.
4.5 Turning off error-correction
To turn off the MNP/V.42 error correction and communicate with non-MNP/V.42 modems:
1. Type AT\N0 and press the Enter key to return to standard operation with buffering. or
AT\N1 and press the Enter key to return to standard operation without buffering.
2. Your modem responds with OK.
4.6 MNP5 and V.42bis data-compression
There are two major data-compression protocols used in data communications, MNP5 and
V.42bis. MNP5 was the first data-compression protocol to be developed and provides a
data-compression ratio of 2:1.
In January 1990, ITU-T ratified the V.42bis data-compression protocol as the international
standard. V.42bis performs significantly better than MNP5, providing a data-compression
ratio of approximately 3:1 − and in some case, up to 4:1.
By supporting both types of data-compression protocols, your modem can communicate
with the installed base of MNP5 and V.42bis modems and modems.
To communicate with remote MNP5 modems only
1. Type AT%C1
2. Press the Enter key. Your modem responds with OK. When your modem originates or
answers calls, it will try to make an MNP5 connection. If that falls, your modem will
hang up and return to command mode.
To turn off V.42bis and MNP5 data compression:
1. Type AT%C0 ; Press the Enter key. Your modem responds with OK.

Chapter 5 List of modem commands
Chapter 5 describes the modem commands available to your modem. If you will be using
a data communication software program to send and receive files, you will probably not
need to use these commands, because your software program will handle these tasks for
you. However, if you want to bypass your communication software program and perform
modem tasks directly with your modem, you will find the commands described in this
chapter helpful.
Standard modem commands begin at Table 5-1. MNP/V.42/V.42bis commands begin on
page 38. If a command requires parameters such as 0 and 1, the parameter is identified
as n in the left column and described in the right column in the following tables.
Remember that each command, except for +++ and A/, is prefaced by AT and
executed when you press the Enter key. To review the format used to send modem
commands, refer to Chapter 2.
Please refer to Chapter 4 for more information on MNP/V.42/V.42bis error correction and
data compression protocols.
Table 5-1. Standard modem commands
Description
Modem
Commands
+++
Keep data connection and move from data mode to command
mode
When your modem enters the data mode, typing +++ allows it to
escape to the command mode while preserving the connection to
remote modem.
Answer command
Force the modem to go off-hook in answer mode without waiting
for a ring. Use this command to manually answer an incoming call.
A/
Re-execute last command
Repeat the last command line it executed. Not preceded with AT
nor followed by pressing the Enter key. This command is useful
when you want the modem to redial a telephone number that was
busy. The last command line executed stays in the modem's
memory until power is turned off or the modem is reset. Either
action invalidates the A/ command, because there is no command
in memory to execute.

Chapter 6 List of modem S-register
Your modem has S-registers that affect various operating characteristics, let you obtain
information about the modem, and let you test the modem. Each S-Register has a factoryset value, which you can read or change to fit your particular requirements. Chapter 6
explains how to read and change S-Register repeatedly. A sequential list of S-Register is
also provided.
6.1 Reading an S-Register value
To read the current value of an S-Register :
1. Type ATSr? from the command mode, where r is an S-Register number.
2. Press the Enter key. The modem responds with decimal value of the S-Register , in
three-digit form, followed by OK.
To read values from more than one S-Register :
1. Type ATSr?Sr? from the command mode and press the Enter key. For example, to
read the value of Register S0 (auto-answer after the number of rings specified by this
S-Register value) and S1(count the number of incoming rings), type ATS0?S1? from
the command mode.
2. Press the Enter key. The modem displays the first S-Register value, a carriage return,
the next S- Register value, a carriage return, and OK(or 0).
6.2 Changing an S-Register value
To change an S-Register value, use the Sr=n command, where r is an S-Register number
and n is the new value you want to assign to the S-Register. For example, to have the
modem auto-answer incoming calls after the third ring:
Type ATS0=3 from the command mode.
1. Press the Enter key. The modem responds with OK or 0 to show it has executed your
command and changed the S-Register value. The value remains in effect until the
modem is turned off and on, or reset. The modem then revert to its default S-Register
values (in this case, Register S0 returns to a value of 0, disabling auto answer).

Auto-answer
Assigning a value from 1 to 255 in Register
S0 tells the modem how many rings must
occur before it can auto-answers calls. The
default, 0, turns off the auto-answer feature.
Count incoming rings
Register S1 counts the number of incoming
rings when your telephone line rings. When
this value equals the value in Register S0,
the modem auto-answer calls. This SRegister resets approximately 8 seconds
after the last ring.
Escape character value
Register S2 sets the ASCII value of escape
characters, that switch the modem from data
mode to command mode without losing the
connection to the remote modem. Values
greater than 127 disable the escape
feature, preventing a return to the command
mode. To return to command mode with the
escape characters disabled, the remote
modem must hang up or an ON-to-OFF
transition of the DTR interface signal must
occur with &D1, &D2 or &D3 in effect.
Carriage return character
Register S3 sets the ASCII value of the
carriage return (end-of-line) character, This
is the character used to end the command
line(and have the modem execute the line)
and also the character that follows modem
responses.
Line feed character
Register S4 sets the ASCII value of the line
feed character. The modem sends this
character after a carriage return only when
word responses are sent (V1 command in
effect). If a line feed characters is not
wanted, change this register value to a null
character.

Register S7 tells the modem how many

value can be increased if the modem does
not detect a carrier within the specified time.
If the modem detects a remote carrier signal
within the specified time, it sends a
CONNECT response and enter data mode.
If it does not detect a remote carrier within
the specified time, it sends NO CARRIER ,
hangs up, and remains in command mode.

Register S9 tells the modem how long the

signal for a busy signal, ring, or voice. The
default setting requires the modem to the
carrier signal for at least 0.6 seconds before
recognizing it. Increasing the time in this SRegister reduces the chances that the
modem will mistake noise such as a busy

Carrier loss time
Register S10 sets the time between the loss
of a remote modem's carrier signal and
when the modem disconnects. This allows
the remote modem's carrier signal to
momentarily disappear from the telephone
line without the modem disconnecting.
Touch-Tone speed
Register S11 controls the speed of the
Touch-Tone (DTMF) dialing. Increasing this
value to 255 slows the dialing rate to 1.9
digits per second. Do not select a value less
than 50 milliseconds. (Register S11 does
not effect pulse dialing, which is fixed at 10
pulses per second.)
Escape character guard time
Register S12 controls the time delay
required before and after typing the escape
characters. The default setting, 50, equals
one second. To reduce the chance that
transmitted data is mistaken for escape
characters, the S12 value can be increased,
but this makes using the escape characters
time-consuming. If a small value is used, it
may be hard to type the three escape
characters fast enough, especially if the
guard time is less than the time needed to
send 1 character at the current transmission
speed. If S12=0, there will be no time
requirement for typing escape characters.

Delay Before Forced Hang Up
This register specifies the delay between

disconnect (or ON-to-OFF transition of DTR
if the modem is programmed to follow the
signal), and the disconnect operation.
Applicable to error-correction connection
only. This register can be used to ensure
that data in the modem buffer is sent before
the modem disconnects.
If S38 is set to a value between 0 and 254,
the modem will wait that number of seconds
for the remote modem to acknowledge all
data in the modem buffer before
disconnecting. If time expires before all data
is sent, the NO CARRIER result code will be
issued to indicated that data has been lost.
If all data is transmitted prior to time-out, the
response to the H0 command will be OK.
If S38 is set to 255, the modem does not
time-out and continues to attempt to deliver

Chapter 7 Hardware Quick Installation Guide
Before you begin installing your modem, run the following tests first:
Identify an available COM port address and IRQ (interrupt) for your modem.
Do you have either a sound card, a network card, a scanner card, or a bus mouse? If you
do so, find out their IRQ settings from your computer dealer or from the hardware manuals.
7.1 FOR WINDOWS 95
Add a COM Port
1. Please choose START then Settings, then Control Panel. In Control Panel, double
click on Add New Hardware. In the "Add New Hardware Wizard" Click on "Next
>" button. It will then ask you if you want Windows 95 to search for New Hardware,
click on YES, and then the "Next >" button. Read the Warning, and if you agree,
click on "Next >". Now wait for the Wizard to complete its inspection of your system
configuration. You can click on "Details" and if all is correct, then click on "Finish"
button. Then when it asks, click on "Yes" to reboot your computer.
2. Now go to START, then SETTINGS, then Control Panel. Double Click on System.
Then click on the Device Manager TAB. Double Click on "Ports (COM & LPT)".
Whatever COM ports show up, you cannot use for the modem, unless you disable
them first in the BIOS of you COMPUTER, ON the Motherboard or on your I/O Card.
If you choose to disable one of your current ports to put the modem in, then rerun this
test to make sure that it was actually disabled correctly.
3. You can now continue to OPTION 1 of this section.
51
5634RCS User’s Manual
Refer to Chapter 8 to continue the installation of the modem
7.2 FOR WINDOWS 3.1x or DOS
Turn your computer on and go to the "C" prompt (C:\>).
If you have MS-DOS 6.0, or higher, or MS-Windows 3.1x, type MSD (Microsoft Diagnostic)
at "C" prompt. This will not work if you only have Windows 95, (see above section).
MSD is going to give you information on your computer system. Look and see if you
can locate an entry call "COM Port." There should be a number right next to that entry
identifying the number of COM ports you have. Write the number down on a piece of
paper.
Press "C" to go into the COM Port screen.
Write the port addresses for each COM Port down. Regardless of what MSD says,
"03F8" is COM1, "02F8" is COM2, "03E8" is COM3, and "02E8" is COM4.
If it has
"02E8" under COM3, don't worry about it. It just means you skipped a COM Port, this is
very common. You only have to go by the port addresses.
OPTION 1
If you only have "03F8" in the COM Port screen and do not have any sound card, network
adapter, scanner card, bus mouse, or other device using IRQ3, set your modem's
switches or jumpers to COM2 IRQ3 according to the user's manual that cames with your
modem (both COM and IRQ must be set). If you only have "02F8" for COM port, set
your modem to COM1 IRQ4, again following the directions of your Modem User's manual.
OPTION 2
If you have both "03F8" and "02F8" and do not have any sound, network, scanner card,
bus mouse, or other device using IRQ5, set your modem to COM3 IRQ5.
OPTION 3
If you have "03F8" and also have "02E8" and you do not have any sound, network,
scanner card, bus mouse, or other devices using IRQ5, set your modem to COM2 IRQ5.
OPTION 4
If you have "03F8" and also have "02E8" and you do have another device using IRQ5,
please consult your "Multi I/O Card User's Manual" and have COM4 "02E8" IRQ3
disabled. This "Multi I/O Card User's Manual" ought to come with your computer system.
Check with your computer dealer if you can't find one in the package. Set your modem
to COM2 IRQ3 after COM4 IRQ3 is disabled on the I/O card.

OPTION 5
If you have both "03F8" and "02F8" and you do have another device using IRQ5 while you
don't have any external device connected to COM2 "02F8", have COM2 "02F8" IRQ3 on
your I/O card disabled. Set your modem to COM2 IRQ3 after COM2 IRQ3 has been
disabled on your I/O card.
OPTION 6 (depends on your system's multi-I/O card)
If you have both "03F8" and "02F8" and do have another device using IRQ5 while there is
an external device connected to COM2 "02F8" and a serial mouse is connected to COM1
"03F8," you can try to put your modem on COM4 IRQ3. However, this is not always
guaranteed to work. It is our experience that whether or not this kind of setting works or
not depends a lot on the multi-I/O card itself. Sometimes the I/O card does not like to
share IRQ (IRQ3 in this case) with another device. Sometimes this setting will work for
a while and suddenly stopped working. Sometimes it will work flawlessly. The PC
Bus architecture was not designed to share IRQ's.
OPTION 7
If you have a setting that matches Option 6 above and Option 6 does not work on your
system, you can try to move the device that's using IRQ5 to an unused IRQ and set your
modem to COM3 IRQ5. If the device that's using IRQ5 does not support other IRQ's,
you have ran out of available IRQ. Consult your local dealer or a consultant to see if
they can give you some advice. You must also realize that if your system is fully loaded
with no available COM Port or IRQ, another device must be sacrificed (disabled) to make
room for the fax modem.
When you find the COM Port and IRQ setting for your modem, set the modem according
to the instructions in your Fax Modem User's manual. Turn your computer off, unplug
the power cord, remove the cover to your computer, locate an available expansion slot on
the motherboard, remove the screw that's holding the slot cover if there is one, and
carefully slide the modem into the slot completely. Secure the modem in the slot with
the screw. Connect your DEDICATED phone wire to the fax/modem's "LINE" jack.
You may want to install the software that came with the package and test the modem
before you put the computer cover back. But be careful not to touch any system
components with the power cord plugged into the wall socket.
NOTE:
Windows 3.1x Systems (COM Port Packing)
If you are skipping COM3, and you are installing any Windows based communications
software, you will need to add the following two lines to your SYSTEM.INI file's [386Enh]
section:
Example:
COM3IRQ=-1
COM3BASE=03E8

5634RCS User’s Manual
This applies in general to any skipped COM Port, where 'x' is the Port Number skipped.
COMxIRQ=-1
COMxBASE= {note the appropriate port address}
Port Addresses
COM1 = 03F8
COM3 = 03E8
COM2 = 02F8
COM4 = 02E8
