Appendix A AT Commands

AT Command Set

AT commands are issued to the modem to control the modem’s operation and software configuration. The basic command syntax is as follows:

The <command> is a combination of the attention prefix (AT) followed by the AT command. The <parameter> is a string which represents a numeric decimal value.

Note: If a parameter value is not entered then the soft modem assumes a parameter value of zero.

Any command issued is acknowledged with a response in either text or numeric values. These responses are known as result codes.

AT commands can only be entered while the modem is in command mode. Command mode is entered under one of the following conditions:

After powerup, at the termination of a connection, or after the

execution of a command other than dial or answer.

Upon the receipt of the escape sequence (three consecutive characters

matching the contents of register S2) while in on-line mode.

Upon the on-to-off transition of DTR if &D1, &D2, or &D3 has been

set.

A.1 AT Commands

A.1.1 Data and General Commands

+++Escape Sequence

An escape sequence allows the modem to exit data mode and enter on-line command mode. While in on-line command mode, AT commands are sent directly to the modem. Use the return to on-line data mode command (see O<value>—Return to On-Line Data Mode) to return to data mode.

Place a pause before and after the escape sequence to prevent the modem from interpreting the escape sequence as data. The length of the pause is set

Page 31

PCI Modem Card User's Manual

by register S12 (see S12—Escape Guard Time), the escape guard time. Register S2 (see S2—AT Escape Character) identifies the escape sequence character.

A/—Repeat Last Command

Use this command to repeat the last AT command. The modem repeats the command currently in the command buffer. Do not use the AT prefix with this command. Do not conclude the command with a terminating character such as enter.

A—Answer

This command instructs the soft modem to go off-hook and answer an incoming call.

B<value>—Communication Standard Setting

Use this command to select the communication standard used by the soft modem.

B0 Selects CCITT V.22 mode when the modem is at 1200 bits/s.

B1 Selects Bell 212A when the modem is at 1200 bits/s (default).

B2 Deselects V.23 reverse channel (same as B3).

B3 Deselects V.23 reverse channel (same as B2).

B15 Selects V.21 when the modem is at 300 bits/s.

B16 Selects Bell 103J when the modem is at 300 bits/s (default).

C<value>—Carrier Control

This command is supported to ensure compatibility with communications software that issues the C1 command.

However, this modem does not support the C0 command. The C0 command instructs some modems not to send carrier (i.e., it puts them in receive-only mode).

C1 Normal transmit carrier switching (default).

D<dial string>—Dial

This command instructs the soft modem to go off-hook and begin the dialing sequence. The dial string (<dial string>, including modifiers and the telephone number) is entered after the D command.

A dial string can be up to sixty characters long. Any digit or symbol may be dialed as touchtone digits. Characters such as spaces, hyphens, and

Page 32

Appendix A AT Commands

parentheses are ignored by the modem and may be included in the dial string to enhance readability.

This commands select one of the predefined transmission rates. If a rate is entered which is not supported, the transmission rate defaults to the next lower rate.

+IPR=0 Automatic rate detection (default).

+IPR=300 300 bits/s.

+IPR=1200 1200bits/s.

+IPR=460800 460800 bits/s.

+IPR=921600 921600 bits/s.

+MA=<carrier 1>,<carrier 2>, ...—Modulation Automode Control

Use this parameter to define a list of modulations that the soft modem may use to connect with a remote modem for answering or originating automode (automatic modulation negotiation) data calls. The list acts as an extension to the modulation specified by the +MS=<carrier> command. The modulation identified by <carrier> in the +MS command limits the values in the +MA carrier list. Modulations which exceed the rate set by the +MS command, generate an ERROR result code and are not implemented by the soft modem. <carrier> values omitted from the list are not available for automode negotiation and are not used in automode negotiation even when the modem is capable of generating the modulation.

+MR=<value>—Modulation Reporting Control

Use this command to enable or disable modulation report result codes. When the modulation report is enabled, the DCE transmits the +MRR: <rate>, <rx_rate> and the +MCR:<carrier> intermediate result codes to the DTE. The <carrier> reported is the current modulation, for example, V.34. The <rate> reported is the transmit rate in bits per second or is zero if negotiation fails. The <rx_rate> is the receive channel rate and is only reported when different receive and transmit rates have negotiated.

The intermediate result codes are transmitted after the modulation and the

Page 57

PCI Modem Card User's Manual

rate have been determined and before any error control or data compression reports or the final result code (e.g., CONNECT) is transmitted.

+MR=0 Enables the modulation report (default).

+MR=1 Disables the modulation report.

+MS=<carrier>,<automode>,<min_rate>,<max_rate>—Modulation Selection

Use this command to set the modem’s modulation, the modulation’s minimum and maximum transmission rate, and the status of automatic modulation negotiation (automode). The <carrier>, <min_rate>, and <max_rate> parameters define the modulation and its minimum and maximum rates.

The <automode> parameter enables or disables automatic modulation negotiation. If a subsequent +MA command is not provided, the automode parameters are constrained by the modulation set by the <carrier> parameter.

The +MA command can further restrict the automatic modulation negotiation settings but it cannot set a modulation that is higher than the modulation set by the +MS command.

Valid <carrier> Values:

V92 V.92 (default) V90 V.90 V34 V.34 V32T V.32ter V32B V.32 bis V32 V.32 V22B V.22 bis V. 2 2 V. 2 2 Bell212A Bell 212A* V23C V.23, constant carrier, asymmetric FDM V21 V21

Bell103 Bell 103 Automatic modulation negotiation is enabled or disabled by <automode>. However, if a value is specified for the <max_rate>, then automatic rate selection is disabled and the modem will attempt to connect at the specified rate.

Valid <automode> Values:

0 Disables.

1 Enabled (default).

Page 58

+MSC=<src_v34>—Seamless Rate Change Enable

Use this command to enable or disable V.34 seamless rate changes.

+MSC=0 Disables V.34 seamless rate change.

+MSC=1 Enables V.34 seamless rate change (default).

+PCW=<call_waiting>—Call Waiting Enable

Use this command to select how the modem responds to a call waiting signal. The soft modems response is also dependent on the current setting of the caller ID command, +VCID.

Valid <call_waiting> Values:

0 Enable the call waiting detector. When a call waiting signal is

detected, toggle V.24 circuit 125 and collect caller ID as set by +VCID (default).

1 Enable the call waiting detector. When a call waiting signal is

2 Disable call waiting detector.

+PIG=<value>—PCM Upstream Ignore

Use this command to enable or disable PCM upstream in a V.92 connection.

+PIG=0 Enable PCM upstream.

+PIG=1 Disable PCM upstream (default).

detected, hang up the current call.

PCI Modem Card User's Manual

+PMH=<value>—Modem On Hold Enable

Use this command to enable or disable modem on hold. Note, that the +PMH command does not effect the parameters of the +PMHT command. The +PMH command only enables or disables modem on hold. The +PMHT command configures the modem to deny a modem on hold request or grant a modem on hold request with the selected hold time.

+PMH=0 Enables modem on hold (default).

+PMH=1 Disables modem on hold.

+PMHF—Modem On Hold Hook Flash

Use this command to generate a hook flash during modem on hold operations. The command causes the modem to go on-hook for a period of time set by S29. Then the modem returns to the off-hook state for at least 1.5 s.

+PMHR—Initiate Modem On Hold

Use this command to initiate a modem on hold request. Once the local modem receives this request from the user or controlling application, the soft modem requests that the remote modem go on hold. The remote modem either denies the request or grants the request. If the request is granted, the remote modem initialized the modem on hold timer and informs the local modem what the length of the hold duration is. If the request is denied, the local modem generates an ERROR result code and hangs up the line.

+PMHT=<value>—Modem On Hold Timer

Use this command to configure the soft modem to grant or reject a modem on hold request. This command configures the modem so it can respond to a modem on hold request. The command must be executed prior to reception of a modem on hold request. If a modem on hold request is made prior to execution of the +PMHT command, by default, the modem on hold request is denied.

This command also sets the modem on hold timer. The modem on hold timer sets the amount of time the modem will remain on hold waiting for the requesting modem to return to the line. If the timer expires, the soft modem will hang up the call.

+PMHT=0 Deny modem on hold request (default).

+PMHT=1 Grant modem on hold request with a 10 s time-out.

+PMHT=2 Grant modem on hold request with a 20 s time-out.

+PMHT=3 Grant modem on hold request with a 30 s time-out.

+PMHT=4 Grant modem on hold request with a 40 s time-out.

+PMHT=5 Grant modem on hold request with a 1 min. time-out.

+PMHT=12 Grant modem on hold request with a 16 min. time-out.

+PMHT=13 Grant modem on hold request with an indefinite time-out.

+PQC=<value>—V.92 Phase 1 and Phase 2 Control

Use this command to configure the V.92 short training sequence. This command selects which short phases are used during initiation of a connection. Once the modem is configured, use the +PSS command to enable or disable the short training sequence.

+PQC=0 Enable short phase 1 and short phase 2 (default).

+PQC=1 Enable short phase 1 only.

+PQC=2 Enable short phase 2 only.

+PQC=3 Disable short phase 1 and short phase 2.

+PSS=<value>—Use Short Sequence

Use this command to enable or disable the V.92 short training sequence.

A.1.2 FAX Commands

+FAA=<value>—Adaptive Answer

A service class 1 FAX DCE may have the ability to answer as a data modem DCE or as a FAX DCE. It may also be able to change from class 1 FAX mode to data modem operation in response to an incoming call.

Page 62

Appendix A AT Commands

Note: This command controls automatic switching from class 1 to class 0 for call answering only. It does not affect call origination, switching to class 1 from other classes, or switching to classes other than class 0.

+FAA=0 The DCE will answer only as a class 1 FAX device. No

automatic switching of service class will occur based on the calling device type (default).

+FAA=1 The DCE can answer and automatically determine whether to

answer as a facsimile DCE or as a data modem.

A.2 Result Codes

The soft modem AT command handler responds to commands from the caller and to activity on the line via result codes. Table below presents a summary of these result codes.

Two forms of each result code are available. The long-form, or verbose, response is given when V1 is selected, and the short-form, numeric response is given when V0 is selected. The long-form code is preceded and terminated by the sequence <CR> <LF>. The short-form is also terminated by <CR>, but it has no preceding sequence. If result codes are suppressed, nothing is returned to the caller.

Appendix C Glossary

ASCII - An acronym for American Standard Code for Information

Exchange. ASCII is a seven-bit code which defines 128 standard characters, including control characters, letters, numbers, and symbols. An extra 128 characters comprise the extended ASCII set.

Baud Rate - The transmission rate between two serial devices, e.g., modems, fax machines, etc. Measured in Bits Per Second.

Blind Dialing - In blind dialing, the modem continues to dial, regardless of the existence of a dialtone, ring, or busy signal.

BPS - Bits Per Second; the number of bits that can be transmitted in one second.

Carrier Signal - The analog data signal that a modem sends over telephone wires.

COMx - Where (x = 1, 2, 3, or 4), COMx is the name(address) of serial communications ports on personal computers. Each serial port in a personal computer has a different number.

CTS - Clear To Send.

Default - The assumed value that is used for a command parameter when

no other value is explicitly provided.

DCD - Data Carrier Detect.

DCE - Data Communication Equipment.

DTE - Data Terminal Equipment.

DSVD - Digital Simultaneous Voice and Data.

DTMF - Dual Tone Multifrequency(for touchtone dialing).

DTR - Data Terminal Ready.

FSK - Frequency Shift Keying.

GSTN - General Switched Telephone Network.

Make/Break Ratio - The ratio of the off-hook (make) to on-hook (break)

interval is the make/break ratio in pulse dialing.

PCI Modem Card User's Manual

Modem - A combination of the words MOdulator and DEModulator. Modems transform digital data into analog signals and back again.

Nonvolatile Memory - An area of memory inside the modem where the default configuration profile is stored. Values recorded in this memory will not be lost when the power is turned off.

Off-Hook - The condition when the modem has picked up the telephone line.

Off-Line Command State - A modem state in which the modem accepts, interprets and executes commands from an asynchronous computer or terminal.

On-Hook - The condition when the modem has not picked up the telephone line; the telephone is hung up.

On-Line - A carrier signal link with a remote modem has been established; communication is in progress.

On-Line State - A modem state in which the modem is connected with a remote modem. Data can be sent or received from the remote modem in this state. No commands will be accepted from the modem except the escape command which will bring the modem into the on-line command state.

On-Line Command State - A modem state in which the modem can accept or and execute commands from an asynchronous computer or terminal while remaining connected with the remote modem. The user can return the modem to the on-line state by issuing the AT0n command or put it into the off-line command state by issuing commands such as ATZ or ATH.

Parity - An error-checking method by which the modem verifies that the data just sent is correct.

pps - Pulse per second.

Profile - A list of default settings.

Protocol - A technical specification for serial communications; the

protocols supported by the modem are listed in Appendix B.

PSK - Phase Shift Keying.

Pulse Dialing - A dialing form in which each digit is represented by a

series of pulses. Rotary telephones all use pulse dialing.

QAM - Quadrature Amplitude Modulation.

Result Codes - The response the modem returns to the screen upon

executing a command.

Page 77

Appendix C Glossary

RAM - Random Access Memory.

ROM - Read-Only Memory. A chip inside the modem which stores the

factory default settings. This memory cannot be changed.

RTS - Request To Send.

RX - Reception.

S Register - RAM locations in the modem which store the active

configuration.

Serial Port - See COMx.

TCM - Trellis-Coded Modulation.

Touchtone Dialing - A dialing format in which each digit is represented

by a musical frequency.

TX - Transmission.
