EFORE YOU BEGIN

1.1 Features

These Fax/Data/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 Fax/Data/TAM Modem gives your personal computer the ability to send and receive FAX messages over the telephone line like a standard FAX machine. Your Fax/Data/TAM Modem also allows your PC to communicate with other personal computers, terminals or BBS's (Bulletin Bo ard Systems) through the data modem functions.

When used as a data modem your Fax/Data/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 and V.90. When used as a Fax/Data/TAM Modem it communicates with all ITU-T Group 3 FAX machines and is compatible with ITU-T V.27ter, V.29 and V.17. Switching between DATA mode operation and FAX mode operation of your Fax/Data/TAM Modem is done through its firmware, 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.

Note: This manual is written to be used for several models of Fax/Data/TAM Modems. Some of the information in this manual may not apply to your Fax/Data/TAM Modem.

OMMAND REFERENCE

This chapter includes all commands, S-Registers supported by the modem. Before using the commands, make sure your communications software package provides the function of operating the modem through its interna1 commands. If your software does not support the function, ignore this chapter.

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 pressed, the command line will be executed. A line with no carriage return is ignored. 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.

The modem accepts either upper or lower case characters in the command line and ignores any space within or between commands. Typing errors can be corrected with the Backspace key. Exceptions are noted in the description of specific commands.

Variables (r and x) are listed in italics. Punctuation symbols (, ; ! @) use as dial modifiers are listed alphabetically according to their English names at the beginning of Section 5.2 where two commands are separated by a slash, either command will have the same effect. For example, if the command is listed as B0/B, issuing either B0 or B will have the same effect.

Note: Except for the A/ command and the + + + escape command described in Section 5.3, 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 keys.

5.1 AT Commands

5.1.1 Basic Command Set

A Go On-line in Answer Mode (For FAX Mode)

This command inst ructs the modem to go off-hook imm ediately and then m ake a handshake with t he remote modem. Handshaking is not available during leased line operation.

Bn Select Protocol to ITU-V.22 or Bell 212A

D Go On-line in Originate Mode D instructs the modem to go of f-hook imm ediately and autom aticall y dial the num ber contained in the

dial string following D. The dial stri ng may contain any of the dia l modifiers c ontained in the following section. The D command without a di al s tri ng is us ual ly us ed to switch from voice conver sation to data communication or to call a remote modem in leased-line operation mode.

En Command Echo

B0/B Selects ITU-V. 22 prot ocol once the command line pref i x AT has been entered at the 1200 bps

data rate.

B1 Selec ts BELL 212A protocol once the command line prefix AT has been entered at the 1200 bps

data rate. (Default)

5.2 Dial Modifiers

This section describes all of the dial modifiers that 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

",", 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 overflowthe 40 character command buffer if placed all in one command line, so it must be broken into two or more command lines. Each part

Page 34

External Modem User's Manual

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.

P Pulse Dialing P, placed ahead of a number, tells the modem to dial a number using pulse dialing.

S Dial a Stored Number

S is used to dial one of four numbers stored in nonvolatile memory. For example, instead of entering a dial string, you can use this command:

Command: ATDS=1<CR>

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.

5.3 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.

Chapter 5 Command Reference

5.4 S Register Reference

Your modem has status regi st ers. 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. The S registers are summarized in 5.4.1, along with their default values. Registers denoted with an " * " may be stored in one of the two user profiles by entering the &Wn command. One of these profiles may be loaded at any time by using the Zn comma nd. The factory default values are stored in ROM and are loaded into the active configuration at power-up or by the Zn command. In addition, the designated default profile is subsequently loaded, and may change some of the factory default values. The designated default profile can be changed by entering the &Yn command, where 'n' is one of the two possible user profiles. The factory defaults can be loaded at any time by entering the &F command.

5.4.1 Register Summary

Important: The contents of the following registers are for reference. The following chart summarizes your modem's registers:

5.4.2 Glossary of the 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 Counter 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.

Page 36

External Modem User's Manual

Range: 0 - 255 rings

S2 Escape Character S2 holds the decimal value of the ASCII character used as the escape character. The default value

corresponds to an ASCII '+'. A value over 127 disables the escape process, i.e., no escape character will be recognized.

Range: 0 - 255, ASCII decimal.

S3 Line Termination Character S3 sets the decimal value of the command line and result code terminator character. Pertains to

asynchronous operation only. Range: 0 - 127, ASCII decimal.

S4 Response Formatting Character S4 sets the decimal value of the character generated by the modem as part of the header, trailer, and

terminator for result codes and information text, along with the S3 parameter. If the value of S4 is changed in a command line, the result codes issued in response to that command line will use the new value of S4. The Response Formatting character is output after the Line Termination character if verbose result codes are used.

Range: 0 - 127, ASCII decimal.

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.

Range: 0 - 127, ASCII decimal.

S6 Wait Time before Blind Dialing

S6 controls how long the modem waits after it goes off-hook before it dials the fir s t digit of the telephone number. The modem always pauses for at least 3 seconds, even if S6 is set to less than 3 seconds.

Range: 3 - 7 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 off-hook when answering a call.

S7 also contr ols 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.

Page 37

Chapter 5 Command Reference

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: 1 - 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.

S10 Lost Carrier To Hang Up Delay S10 sets the length of time, in tenths of a second, that the modem waits before hanging up after a loss

of carrier. 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 sets the duration of tone in DTMF dialing. This value has no effect on pulse dialing. Range: 50 - 255 milliseconds.

S12 Escape Guard Time

S12 determines the escape guard time. The escape guard time is the minimum waiting time required before and after entering the escape code (three consecutive escape characters) in the on-line state. It is also the maximum waiting time allowed between any two consecutive escape characters. If the waiting time before or after the escape code is shorter than the guard time, or if the waiting time between consecutive escape characters is longer than the guard time, then the modem does not recognize the escape command and stays on-line.

If the escape guard time is set at 0 second, it is impossible to return the modem to command state.

Range: 0 - 255 fiftieths of a second. S14 Bit Mapped Options

S25 Delay to DTR

Page 39

Chapter 5 Command Reference

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.

Range: 0 - 255 (0.01 second)

S26 RTS to CTS Delay Interval

Pertains to synchronous operation only. When CTS tracks RTS (&R0) 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

6.1 Troubleshooting

This chapter describes common problems in the installation, configuration and regular usage of your Fax/Data/TAM Modem. To test the Fax/Data/TAM Modem, a communication software package is needed and the package must include a mode that allows you to operate your Fax/Data/TAM Modem by directly issuing internal commands to the modem.

Follow the procedures in the following sections to resolve these common pr oblems: 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 "K" 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.

4. Issue the command: AT&F&W <CR>, if a "0" or "K" result cod e is displayed on the screen, your modem is OK. Otherwise, contact your dealer for assistance.

Your Modem Does Not Connect After It Has Dialed a Phone Number 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 baud rate.

You Can 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 bit, and parity.

6.2 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.

6.3 Application Examples

6.3.1 Dialing a Remote Modem

Command line: ATDP9WT002, (886)-7128423<CR> This command line instruct the modem to dial a r emote modem through a PBX. The modem

first use pulse dialing to dial 9 (the access code of the PBX), wait for outside dial tone, and then use touch tone dialing to dial 002 once a one-second continuous dial tone is detected within 30 seconds, pause for 2 seconds (if S8=2) and then dial 8867128423.

6.3.2 Dialing a Stored Number

Command line: AT&Z2=T03,709394<CR> Command line: ATDS=2<CR> The first command line store the dial string T03, 709394 to the 3rd location in NVRAM.

Afterwards yo u can use the second command line to dial this stored number. The dial string T03, 709394 will appear on the screen to indicate the number being dialed.

Page 43

6.3.3 Manual Answer an Incoming Call

Command line: ATA <CR> The factory setting of the S-register S0 is S0=0. This condition disables the auto answer

capability so that you must issue an ATA command to answer a call. At power up, your modem always monitors if there are incoming rings. If incoming rings are detected, your modem will display result codes on the screen as :

RING : : RING Seeing that, you may issue the ATA command to answer the call. This command must be

entered within the quiet interval between any two rings.

Chapter 6 Modem Reference

6.3.4 Auto Answ er an Incoming Call

Command line: AT S0=2 &W &Y <CR> Auto answer can be enabled by changing the setting of the S-register S0 to a value between 1

and 255. In the above command line, S0=2 instructs the modem to answer an incoming call automatically after the 2nd ring. The &W command writes this configuration to profile 0 in NVRAM. &Y command instruct the modem to load profile 0 as the active configuration on power-up. The last two commands make S0=2 the default value at power-up or reset.

This example also shows the insertion of space between two neighboring commands to make the command line more readable.

6.3.5 Voice to Data Switch

Command line: ATA <CR> or ATX1D <CR> If you are talking with a remote modem user through the telephone set and want to initiate data

communication with the remote modem, follow the procedures below:

1. You or the remote user issue an ATA command first to switch to data communication.

2. When the person on the other end hears an answer tone from the phone, issues an ATX1D command (X1 to disable the dial tone monitor) to instruct the modem to go offhook and wait for a carrier. If connection is successful, the CONNECT XXXX result code will be displayed on the screen. Now you can hang up your phone and begin data communication with the remote modem.

+VCIDn - Caller ID (Enables or disables Caller ID.)

This command only apply to models which support the Caller ID function.

+VCID=0 Disables Caller ID.(Default.) +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:
