1) The modem unit.
2) This user manual.
3) An RJ-11 to RJ-11 phone cable.
4) Data and fax communications software (Optional).
5) W indows 95/98 Driver
Carefully inspect the package for shipping damage. If damage is
found, repack the modem in the original packing material and
contact your dealer.
1.3 A Look at the Modem Card

1.4 The Serial Port and Interrupt of the Modem Card
Each peripheral device, such as a modem, uses a port that is
either serial or parallel, depending on its design. Each port can
only accept one device; otherwise, there is a conflict.
Your modem is designed for use with serial ports. You can use any
COM port, COM1 to COM4. Some computers, may support only
two serial ports. See your computer manual for the number of
ports on your computer.
Computers use interrupts (IRQ) to control the data flow between
computers and peripherals. An interrupt signals data to flow or to
stop, much like a traffic light controls the flow of traffic. Each serial
port needs an interrupt to control that particular port.
1.5 Setting the COM Port and Interrupt of the Modem Card
Your modem is factory set for use on COM4 with IRQ3. If you
choose to use it with another serial port or interrupt, you need to
change the COM jumper and IRQ jumper. Make sure the port and
interrupt set-up you use are not used by any other peripheral.
The COM/IRQ settings should appear as in the diagram below. If
you have any questions about setting a port for your modem
consult your dealer.

1.6 Installing the Modem Card
The modem card is designed for reliability, but it should be kept
away from static electricity, shock, heat, and humidity.
Page: 5
Install the modem into your computer as follows.
1) Turn off the computer
2) Remove the cover of your computer and locate the 5614HP
expansion slot. Refer to your computer installation guide.
3) Plug in your 5614HP modem to the expansion slot, and make
sure the connectors of the modem card are exactly aligned
with the expansion slot.
4) Secure the modem card to the computer with screw.
5) Connect the telephone line from the wall outlet to the jack
labeled LINE.
6) Connect the line from your telephone to the jack labeled
PHONE. You may leave the PHONE jack unconnected.
CAUTION:
Handle the card only by its edges. The card precision components are easily damaged by static electricity or abuse.
The metal bracket of the modem card should rest firmly on
the rear panel bracket of the computer. If not, remove the
modem card and try again.
1.7 Testing the Telephone Line Prior to Connection
The quality of the telephone line significantly affects the reliability
and quality of data communications. Make sure that both the
telephone system and telephone line are in good order before the
modem is connected.
Test the line by lifting the telephone handset and listening for a
clear dial tone. Try placing a few calls. If the calls do not go
through well or are not loud and clear, you may have a poor quality
telephone line. In this case, find a better quality line for your
modem to ensure reliable data communications.
We strongly recommend that you connect the modem directly to
an outside telephone line. Do not connect your modem to a Private
Branch Exchange (PBX) telephone system unless the system is
proven to perform well under data transmission conditions.
1.8 The Communications Software Configuration
Your modem follows the standard modem command set. Most of
Page: 6
the popular communications software packages work with your
modem. If you have any problem using the software, please
contact your software dealer, publisher, or modem dealer.
To install the software, turn on your computer and modem, and
boot the communications software. Follow the software manual
instructions to execute software installation.
Software configuration procedures vary with each software program, computer, and application. Refer to your software manual for
more information. If you experience any difficulty, consult your
dealer.
When installing the software, pay particular attention to the following parameter settings, as many beginners fail to successfully set
them correctly.
1) The serial port number.
2) The communications protocol.
3) The data format, including data bit, stop bit, and parity.
The serial port specified in your communications software must
match the serial port to which the modem is actually connected.
No matter whether it is COM1, COM2, COM3, or COM4, a port
can be only be connected to one peripheral device, and should be
specified so. Otherwise, the two devices will conflict with one
another, or your computer will not be able to find the proper COM
port or other device.
To communicate successfully, the protocol and data format of the
two modems on-line must be identical. For example, if the bulletin
board you are going to dial supports Bell standard, 8 data bits, no
parity, 1 stop bit, you should specify this set-up exactly. Otherwise,
the connection will be unsuccessful and any data received will be
unreadable (garbled).
1.9 Software Configuration Tips
For most PC data communication applications using up-to-date
communication software, the factory default settings are sufficient.
However, you may have to reconfigure your modem if this is not
the case.
Almost all compatible software applications use a similar dialing
prefix command summary. If required, you can use the command
summary to overwrite modem parameters.
Page: 7
Most popular communication software packages allow users to
specify a command string and the dialing prefix that is sent to the
modem prior to dialing telephone number digits. The dialing prefix
reconfigures the modem according to your commands.
Below are some examples of a dialing prefix string:
ATS0=3 Instructs the modem to auto-answer an
incoming call on the third ring.
ATX4DT9W Instructs the modem to first tone-dial the
number 9 and hold it until a dial tone is
detected.
ATS6=10DP Instructs the modem to wait for 10 seconds
before proceeding to dial.
ATM2L3DT Turns on the modem monitoring speaker at all
times, and uses high volume.
ATB0DT Uses the CCITT protocol to establish
connection with the remote modem.
AT&P1DP Pulse dials with the make/break ratio of 33/67
(for use in most European countries).
AT&P0DP Pulse dials with the make/break ratio of 39/61
(for use in the USA).
You may use any command or combination you need. Refer to the
chapters in this manual regarding modem commands for more
details.
1.10 Getting Started
Now, you can dial a bulletin board, data base, or remote computer.
Your modem establishes the connection automatically. Once there
is a connection, you can,
1) read or send electronic mail,
2) view up-to-date news or information,
3) upload or download computer programs,
4) transmit or receive a text message or spread sheet data, or,
perform whichever on-line data communication tasks you
require.
Note that the remote modem should be set to accept digital
loopback request by issuing AT&T4.

Chapter 2
Modem Fundamentals
This chapter provides a brief overview of how modems work.
2.1 Modem Basics
Modems let computers communicate with other computers using
normal telephone lines or leased lines. Your modem sends
communications by modulating (converting) data into sound waves
that a telephone can transmit and another modem can receive.
Your modem receives communications by demodulating sound
waves from the telephone into data your computer can recognize.
The term modem is an abbreviated way of describing this
modulation/demodulation process.
In addition to converting data to sound, a modem performs
functions such as dialing, answering calls, and adjusting settings
for local telephone conditions. Commands must be issued to the
modem to control these functions and settings.
2.2 Data Format
In asynchronous serial communications, data bytes are
disassembled into individual bits and then transmitted bit by bit
along with interval bits and checksum bits, in the order of start bit,
data bits, parity, stop bits, and so on.
The interval bits, start bit, and stop bit, signal to the receiving party
the beginning and end of a byte. The checksum bit and parity allow
the receiving party to check the accuracy of the received data.
The pattern in which a byte is disassembled is called the data
format. Modems at both ends of a link should use the same data
format. Otherwise, the data may be misinterpreted and appear
garbled.
The most commonly used data formats include the following types.
Before you dial a bulletin board or connect on-line with any remote
modem, make sure your modem supports the required data format,
your software can specify the required data format, and that you
have specified the correct data format.
