l The modem

l A modular telephone cable to connect your modem to the telephone line

l Power adapter

l This installation guide and user's manual

l Communication software and manual (option)

l You will also need an available RS-232 serial port on the personal computer and a

properly configured RS-232C interface cable.

l Microphone (option)

l Stereo audio cable (option)

l 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:

l Some type of communication software, if not included.

l 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:

l An available RS-232-C serial port.

5634RCS User’s Manual

l 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.

l 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

the back of the modem (see Figure 1-1).

2. Plug the other end of the cable into the appropriate RS-232C connector on your

computer or terminal. If you need assistance, refer to the manual that accompanied

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. Connect the telephone's modular cord into the PHONE jack on the back of your

modem (see figure 1-1).

2. 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

connector. After you’ve inserted the external MIC or speaker, the default built-in speaker

will be disabled.

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

l If you want to turn off your modem, set the POWER switch on the back of the modem

to the OFF position.

1.11 Modem LEDs

The modem has 9 front panel LEDs, which keep you constantly informed of the modem's

status. Figure 1-4 shows the LEDs.

receives from your computer, indicating that the computer wants to

transmit data.

CD CD is the Carrier Detect LED. This LED goes ON when the modem detects

a remote modem's carrier signal.

OH OH LED is the Off Hook. This LED goes ON when the modem is off-hook

(using the telephone line).

RD RD is the Receive Data LED. This LED blinks each time your computer

receives data from your modem. When data is received at a fast rate, the

LED may appear to be ON.

TD TD is the Transmit Data LED. This LED blinks each time data is being

transmitted from your computer's serial port to your modem. When data is

being transmitted as fast data rates, this LED may appear to be ON.

5634RCS User’s Manual

LED Meaning

TR TR is the Data Terminal Ready LED. This LED goes ON when the modem

is receiving a Data Terminal Ready (DTR) signal from your computer. Your

computer sends this sign al when the computer is ready to send or receive

data ( DTR is ON ). This LED does not work with Macintosh, which uses

the DTR signal for hardware flow control purposes.

MR MR is the Modem Ready LED, This LED goes ON when your modem is

connected to an AC outlet and turned on.

5634RCS User’s Manual

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.

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 re-

execute 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

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.

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.

l 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 error-

correction data connection is made, send the \V0 command.

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 (refer to Chapter 6 for a description of

these registers):

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

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

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. Type ATZ0

2. 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.

5634RCS User’s Manual

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:

l MNP level 1 through 4

l 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-T-

specified 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.

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.

5634RCS User’s Manual

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.

l 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

Modem

Commands Description

+ + + 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.

AAnswer 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.

S-

-r

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 factory-

set 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).

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

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

This register specifies the delay between

the modem’s receipt of the H command to

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

data in the buffer until the connection is lost

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

n 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.

5634RCS User’s Manual

n 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.

5634RCS User’s Manual

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)

This section provides recommended initialization strings for various conditions for those

models that are included in this manual. Please be advised that these recommended

initial strings were produced by our technicians for general usage only. If you want your

modem to perform specific operations, it is your responsibility to find out what the software

packages or the on-line service requires and go over this manual to find the necessary

commands to enable or disable features on the modem. If you are unable to find a

proper initialization string for your modem, please have the software company or the

service provider contact us. We will try to work out a recommended initialization string

for you. Thank you.

A recommended initialization string for general purpose data communications:

5634RS AT&F&C1&D2&K3\N3%C3

Recommended initialization to turn off error-correction, data-compression and flow-control

as required by many of the banking software. Some software also requires numeric

response instead of word response.

5634RCS AT&F%C0\N0&Q0+MS=*

Note: Add V0\V0 to the end of the initialization string if numeric response is required.

Usually, you will need to tell the modem to start its negotiation at a particular speed.

Please go back to the section in chapter 5 that tells you about your +MS command

and set the value accordingly.
