Chapter 1 Installing the modem
Chapter 1 provides detailed instructions for installing your modem.
1.1 Checking your components
Unpack your components and make sure you have the following items:
The modem.
A modular telephone cable to connect your modem to the telephone line.
This user's manual.
Communication software and manual.
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.
A telephone set and line. (if you do need to use a telephone with your modem)
You also need an available card slot in the personal computer.
1.3 Installing the modem
The following instructions explain how to install the modem in a IBM compatible type
personal computer. If you will be installing the modem into a different computer, refer to
the manual that accompanied your computer or contact your computer dealer for
instructions on installing the modem in your personal computer.
1.4 Removing the computer cover
Turn off the personal computer's power. No power must be applied to your computer when
you install the internal modem and computer could be damaged.
Make sure you can freely access the back of the personal computer.
Unscrew the necessary screws to loosen the computer cover. Then set the screws in a
safe place and remove the computer cover.
1.5 Setting the modem switches
Read this section if :
l You have a serial communication card for another modem.
l You will be configuring the internal modem for a communication port other than COM1.
If your computer contains a serial or multifunction card, you may have to change the
COM1 address of the modem so that your personal computer can then communicate with
5634BIF User’s Manual
your serial or multifunction I/O card at one COM port and your modem at another.
The COM port setting is a "logical" address, and has nothing to do with the slot in which
the modem(or serial adapter) is installed.
To change the default COM port setting from COM1 to another setting :
1. Set the switches ( jumpers ) on the modem to specify COM2, COM3, or COM4. Figure
1-1 shows the switch locations on the modem. Table 1-1 describes the setting.
2. Configure your communication software to the new COM port and IRQ settings.

As Table 1-1 shows, a serial device configured to use COM1 will conflict with another
serial device configured to use COM3 which happen to select IRQ4, because these ports
share the same interrupt. To avoid this conflict, one of device should use COM4. Similarly,
a serial device on COM2 will conflict with a serial device using COM4, because these
ports share the same interrupt (IRQ3). In this case, one of the devices should use COM3.
Whichever COM port setting you use, make sure the software you are using is set up to
address that port.
For maximum flexibility, your modem supports IRQ2-5 interrupt requests. Typically, you
will use IRQ3 or IRQ4. However assume your PC has a serial printer configured as COM1
and serial mouse configured as COM2. If you want to use your modem while printing in
the background, you cannot set the modem to COM3 (which uses IRQ4) because the
IRQ4 setting for COM3 conflicts with the printer using COM1, which also uses IRQ4.
Setting the modem to COM4 (IRQ3) conflicts with the mouse using COM2 (IRQ3).
To solve this problem, you can use Jumper 1(JP1) to select IRQ2 or IRQ5( refer to table
1-1). This means that you can print in the background using a printer configured as COM1,
use a mouse configured as COM2, and perform modem activities all at the same time!
IRQ settings 2 through 5 should be used only if you have no other choice. Not all PCs and
DOS versions support IRQ5. IBM PC/AT computers and compatibles should be able to
use IRQ2 or IRQ5, so long as the computer does not have a parallel port set up as LPT2
or another device that is using IRQ2.
5634BIF User’s Manual
1.6 Inserting the modem
The internal modem can fit into any available slot in your personal computer. To insert the
internal modem in your personal computer:
1. Position yourself so that you can easily access the computer's expansion slots.
2. Select any available half-card slot into which you can install the internal modem.
3. Remove any slot cover that may be over the slot. Then remove the slot cover and
keep both in a safe place (you will need the screw to secure the internal modem and
you may need the slot cover if you decide to remove the internal modem in the future).
4. Hold the internal modem above the slot you selected, making sure the modem's edge
connectors are pointing down toward the base of the personal computer (see Figure
1-3).
5. Carefully slide the modem into the slot, applying even pressure to both ends of the
modem. Stop inserting the modem when its gold-plated edge connectors are aligned
with and completely fit into the base of the computer.
6. If you removed a screw from the slot cover, use that screw to secure the modem in the
slot. You may want to test the modem's telephone connection (described in the next
section) before securing your modem.
7. Use the cover-mounting screws to secure the computer cover.
Figure 1-3. Inserting the modem
1.7 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 the modem and plug it
into the LINE modular telephone jack on the back of the modem ( see Figure 1-3).
4. Plug the other end of the telephone cord into the telephone jack on the wall, as you
5634BIF User’s Manual
would any modular telephone.
1.8 Connecting to your Fax Machine
Your modem is so convenient, it provides a second modular telephone jack that lets you
connect your fax machine 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.
1. Use the following procedure to connect your fax machine to your modem:
2. Connect the telephone's modular cord into the PHONE jack on the back of your
modem (see Figure 1-4).

1.9 Connecting to the microphone and speaker
For voice message recording and playing, your modem provides MIC and SPK jacks that
let you connect your microphone and speaker to the modem.
Use the following procedure to connect your microphone and speaker to your modem :
1. Connect the Microphone speaker plug cord into the MIC and SPK jacks on the back of
your modem (see Figure 1-4).
1.10 Verifying your connection

Figure 1-5. 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 computer
manual to find out the appropriate command to use.
Then use the following procedure to verify that your connections:
1. Type AT and press the Enter key. If your system is operating properly, your modem
sends an OK response to your screen and wait for your next command.
If you did not receive a response, make sure your computer is sending commands to
your modem. 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
AT D 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 TouchTone dialing is supported in your calling area, type ATDT 5552121.
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 communications. If you will be communicating directly
with your modem, or if you want to find out more about the modem's operation, proceed to
Chapter 2.

When you turn off your computer, the modem will turn off automatically. It will turn
on again when you turn on the computer.
5634BIF User’s Manual
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 30)
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.
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
10
5634BIF User’s Manual
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
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
11
5634BIF User’s Manual
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(see page 19). 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 (see page 19), 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(see page 19), except BUSY
and NO ANSWER.
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 (see page 19), 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
12
5634BIF User’s Manual
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(see page 19). 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(see page 19).
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
1.
17
Press the Enter key. The next time you turn on or reset your modem, it will drive its
5634BIF User’s Manual

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.
19
5634BIF 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 nonMNP/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.
2.
Type AT%C1
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 37. If a command requires a 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
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.
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.

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.
2.
Type ATSr? from the command mode, where r is an S-Register number.
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.
2.
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.
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:
1.
2.
Type ATS0=3 from the command mode.
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).

Description
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 S-Register
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.
13
Carriage return character
(Carriage Register S3 sets the ASCII value of the carriage
Return) 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.
10
Line feed character
(Line
Register S4 sets the ASCII value of the line
Feed)
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.
Backspace character.
(Backspa Register S5 sets the ASCII value of the
ce)
backspace character is the one created by
passing the Backspace key and the character
echoed to move the cursor to the left. To
change this value, assign an ASCII value
between 0 and 32 or greater than 127. Do not
use values between 33 and 126 since they
correspond to printable ASCII characters.

Description
Dial tone wait time
Register S6 determines how long the modem
waits before dialing the first digit in Dial
command line. This feature is convenient when
it takes longer than two seconds to obtain a dial
tone.
Carrier wait time
Register S7 tells the modem how many seconds
to wait for a remote modem's carrier signal
before hanging up. The S7 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.
Comma pause time for dial delay
Register S9 tells the modem how many seconds
to pause for each comma (,) in a Dial command
line. The comma is used when dialing through a
PBX or other special telephone service to wait
for an outside telephone line.
Carrier detect response time
Register S9 tells the modem how long the
remote modem's carrier signal must be present
so the modem does not mistake 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 S-Register reduces
the chances that the modem will mistake noise
such as a busy signal or voice foe carrier signal.
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 TouchTone (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 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 timeout and continues to attempt to deliver data in
the buffer until the connection is lost or the data
is delivered.

Chapter 7 Hardware Quick Installation Guide (Internal
Non-PnP)
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.
Refer to Chapter 7 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.
43
5634BIF User’s Manual
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, network,
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 came 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 to 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.
44
5634BIF User’s Manual
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
