General Description
This PC Card Fax/Modem is a credit-card-size Type II PCMCIA
card that complies with the PCMCIA 2.1 standards and works with
computers that incorporate a compatible interface.
It is Bell, ITU-T (formerly CCITT) compliant and Hayes AT
command compatible, allowing it to be used worldwide with
today’s popular communication software programs. You will be
able to send and receive faxes to/from any Group 3 compatible fax
machine. Using standard phone lines, the data communication
functions of the modem will enable you to successfully hook up to
the Internet, transmit E-mail, send and receive information and
communicate with other PCs, Bulletin Board Services (BBS) or
computer networks such as Compuserve.
Unpacking Information

Hardware Overview
The intelligent high speed Fax/Modem PC Card can be used as
either a send/receive fax machine or a data modem. When
connecting to another fax/modem, the Fax/Modem PC Card
automatically negotiates to the fastest speed that other

1-2
fax/modems can handle. The Fax/Modem PC Card is designed to
work with most of the popular fax/modem communication
software packages. Some software packages will control and
configure the fax/modem for you automatically, however, they are
usually only useful to those who need the modem to perform
special tasks. Or the users can use the AT commands to control the
fax/modem manually.
What You Need to Use Your Modem

Fax/Modem Enabler
MDMEN.EXE is the DOS enabler for the PCMCIA Fax/Modem.
For the system without any Card Services, you can use the enabler
in the bundled INF file disk to enable the Fax/Modem.
The enabler can be installed as DOS command or DOS driver. It
means that you can load the enabler from the DOS prompt or put it
in the AUTOEXEC.BAT or CONFIG.SYS to load the driver every
time you start your computer.
MDMEN /COM=m /IRQ=nn /SLT=n
COM=m Specify the COM port value (m=1 - 4). Default is 2.
IRQ=nn Specify the interrupt request number in decimal.
Default: value 4 for COM1 and COM3, value 3 for
COM2 and COM4.
SLT=n Specify the slot number the Fax/Modem card
plugged.
Default: auto-detection.
Example: MODEMEN /COM=2 /IRQ=5 /SLT=1
Technical Notes for Enabler
1. Most communication software follows the following IRQ and
I/O address settings:
COM Port IRQ No. I/O Address
COM 1 4 3F8
COM 2 3 2F8
COM 3 4 3E8
COM 4 3 2E8
2. If you are using Windows 3.x, you can change the IRQ under
CONTROL PANEL - PORTS - ADVANCED dialog box.
Once you change the COM port and IRQ under Windows, be
sure that the settings match the parameters in the
MDMEN.EXE command line.

AT COMMANDS AND S-REGISTERS
AT commands are issued to the modem to control the modem's
operation and software configuration. AT commands can only be
entered while the modem is in command mode. The format for
entering AT commands is:
TYPE: ATXn
where Xis the AT command, and nis the specific value for that
command.
PRESS: Enter
Any command issued is acknowledged with a response in either
text or numeric values known as result codes. The Result Code
Options Tables in Appendix C list all the valid result codes.
All commands and command-values accepted by the modem, the
OK message will be shown; any entries other than those show OK
response cause the ERROR result code.
This chapter describes how to use the AT commands for the users
who need special parameters in order to meet their applications.
Refer to the appendix for the detailed AT command definition.
How to Use AT Commands
Usually, your fax and data communications software controls the
modem for you. However, you may also want to use the AT
commands. These commands give you complete control over your
modem. Using the AT commands carefully every time, because
they can cause your software to loose its ability to control the
modem. When you do find any AT command causes fax/modem
maul-function, turn the computer off and then on. That will reset
most of the AT command settings to the factory defaults.
In order to use an AT command, you need to have done the
following:
1. Run your communication software.
2. Configure the software for the appropriate COM port and
IRQ setting if necessary.
3. Enter terminal mode (aka command mode, local mode, or
direct mode.). This is usually the mode that communications
software starts up. Then, type the AT command you need,
then press Enter key. For example,

1-11
ATH0<Enter> (Hang up the modem connection)
AT&K3<Enter> (Enable bi-directional CTS/RTS hardware
flow control)
Mostly the AT commands can also be entered in the same
command line. For example,
AT&K3H0<Enter>
As shown above, it is not necessary to put spaces between the
commands (there is no space between AT, &K3, and H0).
The modem usually returns an response at the next line if it
understands the command. The response is usually OK or
ERROR unless the AT command has other extended messages.
Add &W at the end of the AT command string to save the changes
to modem’s memory (refer to &W commands for details),
otherwise the changes will get lost when you restart or shut down
the computer. You can also use Zn command to load the desired
settings automatically when you power up the modem every time.
Type AT&F&WZ if you get lost in the AT command and want to
go back to the factory default settings.
Use AT&V command to view the active settings.
Exception
Do not precede following commands with an AT prefix or
conclude it by pressing Enter.
+++ Escape sequence
The escape sequence allows the modem to exit data mode and
enter on-line command mode. While in on-line command mode,
you may communicate directly to your modem using AT
commands. Once you are finished, you may return to data mode
using the ATO command.
A pause, the length which is set by the Escape Guard Time (S12),
must be used after an escape sequence is issued. This pause

1-12
prevents the modem from interpreting the escape sequence as data.
The value of the escape sequence character may be changed using
Register S2.
A/ Repeat Last Command
This command repeats the last command string entered.
S-registers
S-registers generally affect how the AT commands perform.
Contents of the registers can be displayed or modified when the
modem is in command mode.
To display the value of an S-register:
TYPE: ATSn? where n is the register number.
PRESS: Enter
To modify the value of an S-register:
TYPE: ATSn = r
where n is the register number, and r is the new register value.
PRESS: Enter

1-13
PROBLEMS AND SOLUTIONS
This chapter provides a number of examples of Problems (P:),
Causes (C:), and Solutions (S:). If your modem is not functioning
properly, look up the problem here, or ask your dealer to get the
technical assistant.
P: The modem does not respond to AT commands.
C: The COM port that you set for the modem may be used by
another card in the computer already.
S: Change the COM port for the Fax/Modem PC Card to another
unused port. It might be better to set the COM port to COM3:
or COM4:. Refer to Appendix B for choosing a new COM
port. Even if you are not using the serial port which is set to the
same COM port as the modem, it can still interfere with the
modem. Be sure to update your software COM port setting as
well.
C: The Interrupt that the modem is using may be the same as
which another card is using.
S: Change the IRQ settings to a different unused one. Refer to
Appendix B for choosing a new IRQ. Even if you are not using
a serial port which is set to the same IRQ as the modem, it can
still interfere with the modem. Be sure to update your software
COM port setting as well.
P: The modem does not execute the command line.
C: Make sure you do type AT at the beginning of command
line.
C: Make sure the modem is not in data mode. Type +++ to escape
to command mode if necessary.
C: Make sure your software is set to the same COM port as the
modem is.
P: The modem does not give a response after an AT command
was executed.
C: The echo and/or responses may be turned off by the ATE0Q1
commands. Use AT&V to check that.
S: Use ATE1Q0 then press Enter to change them back.
C: Make sure the modem is in command mode instead of data
mode when you type the AT command. Type +++ to escape to

1-14
command mode if necessary.
P: The modem gives an 'ERROR' response after an AT
command was executed.
C: Make sure you did not type an invalid command.
C: Make sure your command line is 40 characters or less in
length.
P: The modem goes off-hook and disables the telephone line.
C: The modem may be set to auto-answer the incoming calls.
S: Disable auto-answer by typing ATS0=0 then press Enter at the
command line to disable the auto-answer setting.
P: The modem does not auto-answer the phone.
C: Make sure the software do be configured to auto-answer the
incoming calls.
S: Type ATS0=n then press Enter to set auto-answer mode. The
nstands for the number of rings on which the modem will
answer. For example,
ATS0=3
makes the modem answer on the third ring.
P: The software does not control the modem properly or can
not detect the modem.
S: Make sure the software has been set up correctly. Check the
initialization and dial strings.
C: Some TSRs (programs that stay in memory after they are
loaded) may conflict with the communications software.
S: Try starting your computer without loading any TSRs.
P: The characters on the screen are doubled.
C: Both the modem and the software have the echo turned on.
S: Since only one needs the echo, turn off the echo feature of the
software.
C: The remote modem is echoing your typed characters.
S: Type ATE1 then press Enter. Then turn off the echo feature of
the software.

1-15
P: No text appears on the screen when in data mode.
C: The remote modem is not echoing your typed characters.
S: Type ATE0 then press Enter. Then turn on the echo feature of
the software.
C: Your software may not be set to use full duplex or the remote
modem may not be set to use full duplex either.
C: The remote modem may be waiting for you to type commands
before it replies.
P: No text appears on the screen when in command mode.
S: If you can't see the characters you are typing, type ATE1
then press Enter.
P: The modem does not dial the phone number after you
execute the dialing AT command.
C: If you are using touch tone dialing for the phone line that
requires rotary pulses dialing, it may not work. Try
ATDP###### instead of ATDT#######.
P: When your communications software drives the modem to
make dialing, the PC Card does not take any action.
C: Make sure the ATDT dialing prefix is correctly set in the
software you are using.
C: Make sure the software and modem are set to consistent COM
port.
C: The modem may not hang up the last call.
S: Switch to command mode and type ATH then press Enter.
P: The modem can connect to some modems, but not others.
C: The remote modem may not support data compression or error
correction. It might cause the modem to take a much longer
time to negotiate a link.
S: You might try changing the way that the modem negotiates by
using AT&Qn, ATNn, and ATS37=n commands. It might
be better to start with AT&Q0N1 .
P: When dialing another modem,, you receive a 'CONNECT'

1-16
response, but nothing else.
C: The remote modem may be waiting for you to type a
command.
P: The modem speaker does not make any sound when you're
connecting to another modem.
C: The software may have the speaker disabled.
S: Change the setting in your software or use the ATMn
command to turn the speaker on
P: The modem disconnects (looses the connection) in the
middle of use.
C: The remote modem may have locked up.
C: The telephone line may have been disconnected. Check the
telephone company.
C: Your software may have turned off the DTR signal to the
modem.
P: The modem does not connect with another modem.
C: There may be a problem with the remote modem if you do not
hear the high pitched tone from the remote modem.
P: Occasionally, the modem gives a burst of errors.
C: The telephone line may be noisy or bad.
S: Hang up the call and try calling again for getting a better
telephone line.
C: If there are other telephones on the same line that your modem
is using, someone may pick up a telephone on that extension.
C: Your telephone line may have the call waiting feature.
S: Try adding *70 to your ATDT dialing command line,
otherwise ask your telephone company how to disable it
temporarily.
P: The modem gets errors in transmitted data randomly.
S: Try to use V.42 or MNP1-4 when possible.
S: Connect the modems at a slower baud rate.
P: After you download a file, it was not stored on your disk

1-17
drive.
C: If both modems are using MNP or V.42 protocol, then the flow
control may not be setup correctly.
S: Configure your software to use RTS/CTS flow control. That
will cause your computer to pause long enough for the file to
be stored to disk.
P: The text on the screen is not legible.
C: Your software settings may not match the settings on the
remote modem's software.
S: Make sure your data bits, stop bits, and parity settings match
the settings that the other computer is using. The two most
common settings are: 8 data bits, NO parity, and 1 stop bit
(8,N,1) or 7 data bits, EVEN parity, and 1 stop bit (7,E,1).
C: If the telephone line is very noisy, you may be seeing
corrupted data on your screen.
C: Due to poor telephone line conditions, the modem may have
fallen back to a slower communication speed. You may need to
change the baud rate setting in your software to match this
slower speed. To return the modem to the higher speed,
disconnect and re-dial again.
P: When using V.42bis or MNP5, some features are disabled.
C: You may be using a non-streaming protocol, like Xmodem or
Ymodem for file transfer. Those are fine unless you are using
V.42bis or MNP5
S: When using V.42bis or MNP5, you should use a streaming
file transfer protocol like Ymodem-G or Zmodem.
S: Configure your software to use hardware flow control
(RTS/CTS ON).
P: When the modem is connecting to another modem, it
reports a higher connect baud rate that it is really using.
C: The modem defaults to report the modem-to-computer baud
rate (DTE speed) when it responds with CONNECT message.
S: Go into command mode and type ATW2 then press Enter.
This tells the modem to report the modem-to-modem baud rate
(DCE speed or line speed) instead.
