1.1 Features
Thank you for purchase of the internal modem card. Right here we present to
you the outstanding modem; an easy way to install, fully plug and play.
These Data/Fax/TAM Modems combine the features of a 56000(receive
only)/33600/28800/14400/9600 bps data modem and a 14400/9600 bps FAX
modem. Your new Data/Fax/TAM Modem gives your personal computer the
ability to send and receive FAX messages over the telephone line like a
standard FAX machine. Your Data/Fax/TAM Modem also allows your PC to
communicate with other personal computers, terminals or BBS's (Bulletin
Board Systems) through the data modem functions.
When used as a data modem your Data/Fax/TAM Modem uses the standard
AT command set and is fully compatible with ITU-T V.42, V.42bis, V.34,
V.32bis, V.32, V.22bis, V.23, V.22, V.21, MNP 2-5, Bell 103, 212A,
K56flex and/or V.90. When used as a Fax Modem it communicates with all
ITU-T Group 3 FAX machines and is compatible with ITU-T V.27ter and
V.29, V.17. Switching between DATA mode operation and FAX mode
operation of your Data/Fax/TAM Modem is done through its resource, no
hardware settings are required.
The communication software, which should be used, depends on the kind of
machine that you are going to communicate with. If you are going to call a
FAX machine then you must use the Fax software. If the machine that you
are going to communicate with is a modem then you must use a data modem
communications software.

Chapter 6 Command Reference
If you are already familiar with the use of a modem and the Hayes AT
command set, this modem will be extremely easy for you to use. Just read the
installation procedures in the installation manual and you are ready to begin
operation. If you are new to modem communications, we recommend that
you read through this manual first. If you come across terms that you don't
understand, consult the glossary. Words in boldface type are command
names, commands, or default settings. Carriage returns (Enter) are noted with
<CR> or [ENTER]; this does not mean to enter these characters literally; but
instead to press the Enter key.
This chapter provides an alphabetized reference with examples for all
commands for the modem. The system of commands is depicted below in the
figure below.
To use these commands for dialing or configuring the modem, make sure the
communications software package you will be using lets you operate the
modem through its internal commands. If your software permits use of the
modem's internal commands, read this chapter.
Figure 6-1 System of Commands
6.1 General Command Information
Except for the A/ command and the +++ escape command, all commands
must be prefixed with the attention code AT. For instance, the A command
(below) would be entered as: "AT A<CR>". Without the AT prefix, the
command line cannot be executed. Once entered, AT cannot be deleted with
the Backspace or Delete key.
More than one command can be placed on a single line and, if desired,
separated with spaces for readability. Once the carriage return (Enter) key is
27
PCI Modem Card User's Manual
pressed, the command line is executed. A line with no carriage return is
ignored.
The modem accepts either upper or lower case characters in the command
line and ignores any spaces within or between commands. Typing errors can
be corrected with the Backspace key. Exceptions are noted in the description
of specific commands.
6.2 AT Commands
A
Go On-line in Answer Mode
This command instructs the modem to go off-hook immediately and then
make a handshake with the remote modem. Handshaking is not available
during leased line operation.
A is usually used to manually answer an incoming call or to switch from
voice conversation to data communication.
D
Go On-line in Originate Mode
D instructs the modem to go off-hook immediately and automatically dial the
number contained in the dial string following D. The dial string may contain
any of the dial modifiers contained in the following section. The D command
without a dial string is usually used to switch from voice conversation to data
communication or to call a remote modem in leased-line operation mode.
En

connection exists, this command connects the DTE back to the
remote modem after an escape (+++).
Enters on-line data mode with a retrain before returning to on-line
data mode.

Extended Result Codes
29
PCI Modem Card User's Manual
This command selects which subset of the result messages will be used by
the modem to inform the DTE of the results of commands.
Blind dialing is enabled or disabled by country parameters. If the user wishes
to enforce dial tone detection, a "W" can be placed in the dial string (see D
command). Note that the information below is based upon the default
implementation of the X results table.
If the modem is in facsimile mode (+FCLASS=1), the only message sent to
indicate a connection is CONNECT without a speed indication.

6.3 Dial Modifiers
This section describes all of the dial modifiers, which are used in dial strings.
@
Answer
“@”, placed after a phone number, this modifier tells the modem to wait for
5 seconds of silence before dialing the next number in the dial string. @ is
usually used to access a secure computer system that provides a silent answer
as permission for further entrance.
,
Pause
33
PCI Modem Card User's Manual
",", placed anywhere in the dial string, tells the modem to pause for the
number of seconds specified by S-register S8 before processing the rest of
the dial string.
!
Initiate a Hookflash
"!", placed anywhere in the dial string, tells the modem to initiate a hookflash,
which means to hang up for 0.5 seconds and then go off-hook again before
processing the rest of the dial string. This modifier allows access to PBX
features like call transferring.
;
Return to Command State after Dialing
";", which must be placed at the end of the dial string, returns to the
command state after dialing the number placed ahead of it. A long telephone
number would overflow the 40-character command buffer if placed all in one
command line, so it must be broken into two or more command lines. Each
part includes part of the number, and all but the last command line end with
the ";" followed by a carriage return.
^
Tone Control
Toggles calling tone enable/disable: applicable to current dial attempt only.
L
Re-dial Last Number
The modem will re-dial the last valid telephone number. The L must be
immediately after the D with all the following characters ignored.
P
Pulse Dialing
P, placed ahead of a number, tells the modem to dial a number using pulse
dialing.
T
Touchtone Dialing
T, placed ahead of a number, tells the modem to dial a number using
touchtone dialing.
W
Wait for Dialtone
W, placed after a number, tells the modem to wait up to 30 seconds to detect
a one-second continuous dialtone before dialing the next number. W is most
often used in a PBX system to wait for the dialtone of an outside telephone
line.
34
Chapter 6 Command Reference
6.4 Commands Not Preceded by AT
Two commands, A/ and +++, are neither preceded by the attention code AT
nor followed by a carriage return.
A/
Repeat Command
A/ repeats the execution of the last command line stored in the command
buffer. If the last command line is invalid, the ERROR result code will
appear on the screen. Note that A/ cannot be preceded by AT; if it is,
ERROR will appear on the screen.
+++ Escape
+++ followed by AT <CR> allows the modem to escape from the data mode
to the on-line command state (command state without breaking the
established connection.)
To escape, stop transmitting data, wait at least one escape guard time (the
default time is one second), and then enter three consecutive escape
characters (the default character is +) followed by AT <CR>.
The modem will return to the command state and send the OK result code to
the screen. Note that the escape command is the only command that can be
recognized by the modem in the one-line state; it cannot be recognized in the
command state.
6.5 Result Codes
The modem sends a response to the user via the screen after a command is
issued. As shown in the figure below, there are two forms for each result
code: Modem Response code and digit code.

Chapter 7 S Register Reference
Your modem has status registers. These registers are memory locations
inside your modem which control your modem's operation. You usually do
not have to worry about setting any register because the default values work
for most applications.

7.2 Glossary of S Registers
S0
Number of Rings Before Auto Answer
S0 determines the number of rings that must be received before the modem
automatically answers an incoming call. For example, when S0=3, the
modem automatically answers after the third ring. When S0=0, the modem
does not automatically answer an incoming call; it stays on-hook until the A
command is issued manually to answer the incoming call.
Range:
0 - 255 rings
S1
Ring Count
S1 automatically increments its value by one each time the modem receives a
ring while in the command state. S1 is reset to zero if no ring is detected
within 8 seconds.
Range:
0 - 255 rings
S2
ASCII Value of Escape Character
S2 stores the ASCII value of the escape character. Setting register S2 to a
value greater than 127 disables the escape command and you cannot return to
the command state. With escape disabled, in the on-line state the modem
cannot hang up until the power is turned off or the remote modem hangs up.
Range:
0 - 255, ASCII decimal.
S3
ASCII Value of Carriage Return
S3 stores the ASCII value of the carriage return character. (Pertains to
asynchronous operation only.)
Range:
0 - 127, ASCII decimal.
S4
ASCII Value of Line Feed Character
S4 stores the ASCII value of the line feed character, if your computer does
not recognize the default as a line feed, change the value. A value greater
than 127 disables the line feed. When disabled, the line feed character that
precedes or follows a result code is canceled.(Pertains to asynchronous
operation only.)
Range:
0 - 127, ASCII decimal.
42
Chapter 7 S Register Reference
S5
ASCII Value of Backspace Character
S5 stores the ASCII value of the backspace character. The backspace is used
to edit a command line. If your computer does not recognize the default as a
backspace, change the value. (Pertains to asynchronous operation only.)
Set S5 to any value from 0 to 31 or 127. Do not set it to any value from 32
through 126 because these values correspond to printable ASCII characters.
A value greater than 127 disable the backspace and makes it impossible to
edit a command line.
Range:
0 - 32, ASCII decimal.
S6
Wait Time before Blind Dialing
S6 controls how long the modem waits after it goes off-hook before it dials
the first digit of the telephone number. The modem always pauses for at least
2 seconds, even if S6 is set to less than two seconds.
Range:
2 - 255 seconds.
S7
Wait for Carrier after Dial
S7 controls how long the modem waits for a carrier signal from a remote
modem after originating a call or from the calling modem after going offhook when answering a call.
S7 also controls how long the modem waits for a one-second continuous
dialtone after dialing a number followed by the W dial modifier. If the
modem detects a one-second continuous dialtone within the specified wait
time, it proceeds to dial.
Range:
1 - 255 seconds.
S8
Pause Time for Comma
S8 controls how long the modem pauses when a comma ", " is encountered
in a dial string while executing a dial command.
Range:
0 - 255 seconds.
S9
Carrier Detect Response Time
S9 determines how long a carrier signal must be present for the modem to
confirm it. The longer the response time, the easier it is for the modem to
correctly recognize a carrier without mistaking other signals or transient
noise on the line as a carrier.
Range:
1 - 255 tenths of a second.
43
PCI Modem Card User's Manual
S10 Delay between Loss of Carrier and Hang-Up
S10 determines the delay time between the loss of a carrier from the remote
modem and hang-up. This allows for a temporary loss of carrier without
causing the local modem to disconnect. When S10 is set to 255, the modem
functions as if a carrier is always present.
The actual interval the modem waits before disconnecting is the value in S10
minus the value in S9. Therefore, the value in S10 must be greater than that
in S9, or else the modem disconnects before it recognizes the carrier.
Range:
1 - 255 tenths of a second.
S11 DTMF (Touch-tone) Tone Duration
S11 determines the duration and spacing of tones for Dual Tone
Multifrequency (DTMF) dialing. This value has no effect on pulse dialing.
Range:
50 - 255 milliseconds.

ended with the &T0 command.
Range:

S24 Sleep Inactivity Timer
Set the length of time, in units of 10 seconds, that the modem will operate in
normal mode with no detected telephone line of DTE line activity before
entering low-power sleep mode.
Range: 0 - 255 (seconds)
S25 Delay to DTR
S25 serves two purposes. When the modem is operating in synchronous
mode 1, the value assigned to S25 specifies the length of time the modem
waits after a connection has been made before examining DTR. This allows
the modem to ignore an ON-to-OFF transition of DTR, giving the user time
to disconnect the modem from the asynchronous terminal and attach it to a
synchronous terminal, without forcing the modem back to the asynchronous
command mode. During this time, the value for S25 is read in whole seconds.
In all other modes, and after call establishment in synchronous modes 1 and
4, the value is read in 1/100 seconds. In any mode, a change in DTR (ON or
OFF) that persists for a period shorter than the value held in S25 is ignored
by the modem while it is in data mode.
Range: 0 - 255 (1 second for synchronous mode 1;0.01
second otherwise)
S26 RTS to CTS Delay Interval
Pertains to synchronous operation only. When CTS tracks RTS and the
modem detects an ON-to-OFF transition on RTS, this register sets the time
delay before the modem turns CTS to ON.
Range:
0 - 255 hundredths of a second

S38 Delay Before Forced-Disconnect
This register controls how long the modem waits, after receiving the ATH
command or loss of DTR, before it disconnects from the telephone line.
When connected in an error-corrected mode, you can use this register to
ensure that all data is transmitted from the modem's buffer before the modem
disconnects.
If you set S38 between 0 and 254, the modem waits that number of seconds
for the remote modem to acknowledge all data before it disconnects. If you
set S38 to 255, the modem waits indefinitely for the remote modem to
acknowledge all data.

Chapter 8 Testing
The modem provides “local analog loop back ” testing feature to identify
fault location when transmission quality is not good.
8.1 Local Analog Loopback
The local analog loopback test checks the integrity of the local computer or
terminal and the local modem. During the test, the local modem internally
loops data sent from the local computer or terminal back to the same
computer or terminal as shown in Figure 8-1. During the test, data is not
transmitted to the remote modem.
If characters are looped correctly during this test, both the modem and the
local computer or terminal are functioning correctly. If incorrect characters
appear on the screen, either the local computer or terminal or the local
modem is in error.
To perform a local analog loopback, put the local modem in the command
state. If it is on-line, issue the escape command + + +, to return to the
command state.

Here, the test timer is disabled and the modem sets up an internal analog loop
as shown in Figure 8-1. When the loopback is established, the modem goes
on-line and the test message (any character you type) is looped back on the
screen for verification. Finally, +++ returns the modem to the command
state and &T0 ends the test and breaks the internal analog loop.
The following command sequence is the same as the previous one except that
the test timer is set to 60 seconds. At the end of the test time, the timer

Chapter 9 Troubleshooting
This chapter describes common problems in the installation, configuration
and regular usage of your Fax/Data Modem. To test the Fax/Data Modem, a
communication software package is needed and the package must include a
mode that allows you to operate your Fax/Data Modem by directly issuing
internal commands to the modem.
Follow the procedures in the following sections to resolve these common
problems:
No Response From Your Modem
1. If you are using the internal add-on card modems, make sure that the
COM port address you have set your modem to corresponds to the
appropriate selection in the communications software which you are
using.
2. Issue the ATZ command to reset your modem. The returned result code
should be "0" or "OK" depending on what communications program you
are using. Your modem is OK if you get one of these responses. If there
is no response after issuing the ATZ<CR>, continue to the next step.
3. Check if there are any other interface cards in your computer that use the
same COM port address as your modem. If so, you must set your modem
to another COM port address. (Keep in mind that on most systems, only
two COM ports are available. One of them must be used as either 1 or 3,
while the other must be used as 2 or 4.) For example, if a mouse is set to
COM 1, your modem should be set to COM2 or COM4. Continue to the
next step if the COM port address is OK.
4. Issue the command: AT&F&W <CR>, if a "0" or "OK" result code is
displayed on the screen, your modem is OK. Otherwise, contact your
dealer for assistance.
Your Modem Does Not Dial Out
Make sure that your modem responds normally as described in section 8.1. If
you can communicate through the keyboard, check whether the modem is
properly connected to the phone line.
Your Modem Does Not Connect After It Has Dialed a Phone
Number
53
PCI Modem Card User's Manual
The problem may have several causes. The phone line may be too noisy or
the telephone cord may be poor. Try the line with a regular phone. Also the
remote modem may not recognize your modem's baud rate.
You Can't Transmit After You Have Connected to the Remote
Modem
In this case, check the communication parameters of the remote modem, then
configure your software to the same number of data bits, stop bits, and parity.

Appendix A Caller ID Commands
+VCIDn - Caller ID (Enables or disables Caller ID.)(for U.S.A)
This command only apply to models which support the Caller ID function.
+VCID=0 Disables Caller ID.
+VCID=1 Enables Caller ID with formatted presentation to the DTE. The
modem will present the data items in a <Tag><Value> pair format.
The expected pairs are data, time, caller code (telephone number),
and name.
+VCID=2 Enables Caller ID with unformatted presentation to the DTE. The
modem will present the entire packet of information, excluding
the leading U's, in ASCII printable hex numbers.
Result Codes:
OK
n=0 or 2.
ERROR Otherwise.
Inquiries :
+VCID? Retrieves the current Caller ID mode from the modem.
+VCID=? Returns the mode capabilities of the modem in a list with each
element separated by commas.
