CHAPTER 1: Overview

1. Overview

AT commands are used to control your modem’s operation. Each command must be preceded by the characters A and T to get the modem’s attention.

AT commands can be issued only when the modem is in command mode or online command mode. The modem is in command mode whenever it is not connected to another modem. The modem is in data mode whenever it is connected to another modem and ready to exchange data. Online command mode is a temporary state in which you can issue commands to the modem while you’re connected to another modem.

When you need to send commands to the modem at the other end of the connection, put the modem into online command mode from data mode. To do this, you must issue an escape sequence: Type +++ and wait for the OK response. Then issue the hang-up command by typing ATH and pressing Enter. To return to data mode from online command mode, type the command ATO.

To send AT commands to the modem, you must use a communications program (such as PhoneTools, which is included with your modem, or HyperTerminal in Windows ® 95, 98, Me, XP, Windows NT ® 4.0, or Windows

2000). You can issue commands to the modem directly by typing them in the terminal window of the communications program. To issue commands indirectly, configure the operating system or communications program to send the commands automatically. Fortunately, communications programs make modems’ daily operation effortless by hiding the commands from the user. Most users, therefore, need to use AT commands only when reconfiguring the modem (for example, to turn autoanswer on or off).

The format for entering an AT command is ATXn, where X is the command and n is the value for the command, or command parameter. The value is always a number. If the value is zero, you can omit it from the command. AT&W is equivalent to AT&W0.

Most commands have a default value, which is the value that is set at the factory. Default commands are provided with each command in Chapter 2.

You must press Enter to send the command to the modem. Any time the modem receives a command, it sends a response known as a result code. The most common result codes are OK, ERROR, and CONNECT. For a table of valid result codes, see Chapter 6.

You can issue several commands in one line in a command string. The command string begins with AT and ends when you press Enter. Spaces to separate the commands are optional; they are ignored by the command interpreter. The most familiar command string is the initialization string, which is used to configure the modem when it is powered on or reset, or when your communications software calls another modem.

An example of a command string is shown below. This string changes the speaker, enables V.42 error correction, and enables CTS/RTS flow control.

Behavior in Data Mode (+FCLASS=0): When on-hook, if the line is in use and an ATDT is issued, the modem will not go off-hook and will return with the message LINE-IN-USE.

When off-hook and either an extension is picked up or a line reversal is detected, the modem will drop the connection. The disconnect reason is register S86=25 (also defined for #UD). The user must flash the hook in order to get a dial tone because the remote server will be retraining.

If the local handset is picked up while modem is off-hook, the modem will do a link-disconnect, flash the hook for 1.5 seconds, then connect the local handset to the line. Now, the user dial tone is on the local handset. Disconnect reason S86=25.

Behavior in Voice Mode (+FCLASS=8): When in voice mode and an extension is picked-up, a <DLE>P is sent to the DTE. When the modem is off-hook, a line reversal may also be detected in which case a <DLE>l is sent to the DTE.

In voice mode, there is no blocking of ATDT when the line is in use.

Also, there is no automatic hang-up in voice mode as in data mode.

There is only the above stated <DLE> shielding event reporting.

Case 1: Telephone Line is in Use

If an ATDT, ATDP, or ATDL is issued while Line-In-Use detection is enabled and the telephone line is in use, the modem will immediately return the message LINE-IN-USE to the DTE without going off-hook, then return to command mode.

Case 2: Telephone Line is in Use But Disconnected

If an ATDT, ATDP, or ATDL is issued while Line-In-Use detection is enabled and the telephone line is NOT in use, the modem will go offhook after a short pause, then respond with CONNECT or NO

CARRIER message.

Case 3: Telephone Line is Not Connected to Modem

If an ATDT, ATDP, or ATDL is issued while Line-In-Use detection is enabled and the telephone line is not connected, the modem will go off-hook momentarily, go back on-hook, then respond with NO DIAL

TONE message.

Extension Pick-up (Enabled by AT-STE=2, AT-STE=3, AT-STE=6, or

AT-STE=7):

Case 1: Modem Off-Hook, Local Handset Goes Off-Hook

If the local handset goes off-hook while the modem is in a data connection, the modem will then send a GSTN Clear down to the remote modem and then go on-hook. The modem will then send a NO

CARRIER message to the DTE. A result code of 25 will be left in S86 register.

Remote Hang-up (enabled by AT-STE=4, AT-STE=5, AT-STE=6, or AT-

STE=7):

Case 1: Modem Off-Hook, Remote Hang-Up

If the modem is connected (off-hook) and the remote modem/server hangs up, the central office may issue a line polarity reversal. If a line polarity reversal is detected, the modem will drop the call and respond with NO CARRIER. The reason for hang-up can be determined by #UD or by S86=25. A line reversal can also be simulated by simply pulling out the telephone line during a connection.

An automated system that needs to periodically use the line while giving the voice user the highest priority. The automated system makes a connection when the line is free. It does this without disturbing the line if the line is in use. The automated system periodically retries the connection until the line is free.

Once free, it dials and makes its connection. If a voice user wishes to use the line while the modem is connected, the modem drops the line and gives it to the user. The modem will then try to regain control of the line by once again periodically retrying to establish a connection.

3. V.8/V.8bis Commands

V.8 is a way V.34 modems negotiate connections features and options. V.8bis is a start-up sequence for multimedia modems.

Command: +A8E V.8 and V.8bis Operation Controls

Description:

Values:

This command is defined for two conditions: as a parameter while the modem is on-hook, and as an action command while the modem is off-hook. If enabled, V.8 negotiation does not preclude simultaneous implementation of other negotiation means (for example, V.8bis, V.18,

V.32bis Annex A). It is a compound parameter if issued while the modem is on-hook, used to precondition V.8 and V.8bis originating and answering operation. It is issued by the DTE before the Dial (D) or

Answer (A) command, regardless of the state of the +FCLASS parameter. This command is an action command if issued while the modem is off-hook to (re)start V.8 or V.8bis negotiation.

Example:

If initial V.8 negotiation fails, but subsequent T.30 negotiation indicates V.8 capability, this command may be used to initiate V.8

negotiation.

Syntax: +A8E=<v8o>,<v8a>,<v8cf>[,<v8b>][,<cfrange>][,<protrange>]

<v8o> Decimal number which enables/disables issuance of +A8x indications during modem-controlled V.8 origination negotiation.

1 Enable DCE-controlled V.8 origination negotiation without

+A8x indications. Default.

6 Enable DCE-controlled V.8 origination negotiation with +A8x indications.

<v8a>= Decimal number which enables/disables issuance of

+A8x indications during modem-controlled V.8 answer

1 negotiation.

Enable DCE-controlled V.8 answer negotiation without +A8x indications. Default

Enable DCE-controlled V.8 answer negotiation with +A8x 5 indications.

The ATD and ATA commands behave as specified in V.250, and +A8n indications are not generated by the modem. For subparameter values

<v8o>=6 and <v8a>=5, +A8I indications are issued during the V.8session

to notify the DTE when the relevant V.8 signals are received.

+A8E? Reports current or selected values.

+A8E=? Reports supported range of parameter values.

CI Signal Indication

This indication is issued by an answering modem, if +A8E,<v8a> .0, to indicate detection of a V.8 CI signal and report the recovered Call

Function octet(s).

Indication Syntax: +A8I:<v8cf><CR>

<v8cf> A hexadecimal code octet representation of those Call

Function octet(s).

+A8I:0 indicates that the modem timed out waiting for CI.

MNP connection is attempted. If it fails, modem disconnects.

MNP connection is attempted. If it fails, a direct mode connection is established.

An MNP connection is attempted and if it fails, a normal modem connection is established.

20 Delay Before Forced Hang Up: Sets the delay between the modem’s receipt of the H command to disconnect (or high-to-low transition of DTR if the modem is programmed to follow the signal) and the disconnect operation. Applies only to errorcorrection connections. This register can be used to ensure that data in the modem buffer is sent before the modem disconnects. If S38 is set between 0 and 254, the modem waits for the remote modem to acknowledge all data in the buffer before disconnecting. If S38 is set to 255, the modem does not time out and continues to attempt to deliver data in the buffer until the connection is lost or the data is delivered.

Data Compression Control: Enables/disables data compression:

136 Error correction without compression.

138 Error correction with compression.

V.42 Negotiation Control: Enables or disables LAPM negotiation.

An invalid value is treated as a 128 value.

6. Result Codes

CHAPTER 6: Result Codes

The modem responds to commands from the DTE and to activity on the line by signaling to the DTE in the form of result codes. The result codes that the modem can send are described in this chapter.

Two forms of each result code are available: long-form (verbose) response and a short-form (terse) response.

The long-form code is preceded and terminated by the sequence < CR>< LF>.

The short-form is terminated by < CR>, only with no preceding sequence.

If result messages are suppressed, nothing is returned to the DTE. The long-form results codes can be modified by the OEM through the .INF file.

CHAPTER 7: Setting Country/Regional Codes

7. Setting Country/Regional Codes

Countries or regions vary in their requirements for how a modem functions. Therefore, you must configure your modem to match the defaults of your country or region. Choose from any of the three methods:

• Using the LCD panel to set your country or region code.

• Using the global wizard to set your country or region code.

• Using AT commands to set your country or region code.

7.1 Using the LCD Panel

1. Start at the Status LCD and use

↓ to move down the menu tree to the Region Select LCD.

2. Use

→ to move from the Region Select LCD across the Region Settings Options LCD to the Current

Setting LCD.

3. If the current setting shown is not the one for your region, use the arrow keys to get to the Region Profile

LCD. The question mark represents the question: Is this the region you want? If B5 is the one you want, press Enter; if it’s not the one you want, use the arrow keys to get to the code you want. The region code for Japan is 00.

4. When you reach the region code you want, press Enter. You will then see the message Option Set.

5. After setting the region profile, you can cycle the power to the modem (turn it off and then back on again) or use the arrows to move back and up the menu tree to return to the Status LCD.

Region Profile code for Japan is 00 as shown at left

Figure 7-1. LCD panel steps for setting your country code.

7.2 Using the Global Wizard

We recommend the Global Wizard configuration utility for computers running Windows. The Wizard can configure your modem for a specific country with just a few mouse clicks.

1. Insert the modem CD into the CD-ROM drive. The Autorun dialog box appears.

2. Click Initial Setup and Country or Region Selection. The Global Wizard dialog box appears. Click Next.

3. The Global Wizard searches for your modem and identifies it. Click Next after your modem is identified.

4. Select the country or region in which the modem will be used. Click Next.

5. Review your choice. If it is correct, click Next to configure the modem.

6. When the Global Wizard announces that the parameters have been set, click Finish to exit.

CHAPTER 7: Setting Country/Regional Codes

7.3 Using AT Commands

If you are comfortable using AT commands, you can use them to configure your modem. You must enter these commands in your communication program’s terminal window. You can use a communication program such as

PhoneTools.

How to change the country/region code

1. Set and save the country/region code (00) by typing the command AT+GCI=00<CR>.

2. An OK message displays onscreen.

3. The code 00 appears onscreen.

How to verify the code

Type AT +GCI?<CR> or use the command AT+00<CR>.
