AT Command Format A command line is a string of characters sent from a DTE to the modem (DCE) while the modem is in a command state. A command line has a prefix, a body, and a terminator. Each command line (with the exception of the A/ command) must begin with the character sequence AT and must be terminated by a carriage return. Commands entered in upper case or lower case are accepted, but both the A and T must be of the same case, i.e., “AT or “at. The default terminator is the ENTER keycharacter. Characters that precede the AT prefix are ignored. The command line interpretation begins upon receipt of the ENTER key character. Characters within the command line are parsed as commands with associated parameter values. The basic commands consist of single ASCII characters, or single characters proceeded by a prefix character (e.g., “&” or “+”), followed by a decimal parameter. Missing decimal parameters are evaluated as 0. Escape Code Sequence When the modem has established a connection and has entered on-line data mode, it is possible to break into the data transmission in order to issue further commands to the modem in an on-line command mode. This is achieved by the DTE sending to the modem a sequence of +++AT . To issue a disconnect sequence type +++ATH . This format complies with the Time Independent Escape Sequence (TIES). 3 V90K56DOCATC11A AT Command Guide Basic AT Commands Command AT A/ A B0 B1 B2 D Dmn L W T P , ; @ ! ^ S=(0-9) E0 E1 H0 H1 I0 I1 I2 I3 I4 I5 Function Attention - this precedes all commands except A/ Execute previous command - does not require a * Causes the modem to go off hook. If a call is coming in, the modem will try to answer it. The procedure for answering a call is a short silence and then an answer tone. Sending a character to the modem during this procedure will abort the answer procedure. The amount of time the modem will wait for a carrier is programmable by modifying the S7 register. Select CCITT V.22 (1200 bps) Select Bell 212A (1200 bps) Select CCITT V23 Originate mode will transmit data at 75 bps and receive data at 1200 bps. Answer mode will transmit data at 1200bps and receive data at 75bps. The command N0 (Disable auto mode) must be selected. D alone will take the modem off-hook and wait for a dial tone. (See X command for exceptions) The length of time to wait for a dial tone before dialing is programmable in register S6. ATDmn will dial a phone number where m is a modifier: L, W, ,, ;, @, !, or S. It will dial the telephone number n. Dial last number Wait for dial tone. If you have selected X0 or X1 (disable dial tone detection), then you can use this modifier to override that setting. Tone dialing Pulse and Tone dialing cannot be mixed on the same command line. Pulse dialing allows the modem to work on telephone networks where tone dialing is not supported. Pulse and Tone dialing cannot be mixed on the same command line. Pause during dial. The amount of time to pause is determined in register S8. Return to command mode after dialing. It doesn’t wait for carrier or hang up. Wait for 5 seconds of silence. This is used to access systems that do not provide a dial tone. Hook flash. Causes the modem to go on-hook for 0.5 seconds. This is used in PBX systems and for voice features like call waiting. Send 1300Hz calling tone Dials a stored number. Up to ten numbers can be stored, and the addresses are from 0 to 9. To store a number into one of these addresses, use the & Z command. Commands issued to the modem are not echoed to the local terminal. This only matters in the command mode. It does not affect the modem’s ability to send response codes. Commands are echoed to the local terminal. Force modem on-hook (hang-up). Force modem off-hook (to answer or dial). Return numeric product code Return hardware variation code Report internal code Report software revision number Report product feature listing Highest Speed Modulation 4 V90K56DOCATC11A AT Command Guide L0 L1 L2 L3 Speaker volume zero Speaker volume low Speaker volume low Speaker volume low M0 M1 M2 M3 N0 N1 Speaker always off Speaker on until carrier detected Speaker always on Speaker on during answering only Disable auto-mode. This forces the modem to connect at the speed specified in register S37. Enable auto-mode. The modem will connect at the highest available line speed and ignore any ATBn command. Return to data mode. If you have entered the command mode using the time independent escape sequence, this will put you back in data mode without going on-hook. Retrain the modem. If the line condition has changed since the original connection, retraining the modem will cause it to reconnect at the most efficient speed for the current line condition. Enable response to DTE. Disable response to DTE. The modem does not send responses to the terminal. Issuing a command will not produce a response (unless the command is something like ATZ, which will restore this setting to default.) Set default S-register. Any subsequent = or ? commands will modify the default S register. Set register n to value m Return the value of register n Result codes will be sent in numeric form. (See the result code table) Result codes will be sent in word form. (See the result code table. Report DTE speed only. After connection, there will be no message about what Error Correction or Data Compression protocol is in use. Report DCE speed, Error Correction/Data Compression protocol, and DTE speed. Report DCE speed only Send OK, CONNECT, RING, NO CARRIER, ERROR and NO ANSWER. Busy and Dial Tone Detection is disabled. Send X0 messages and CONNECT speed Send X1 message and NO DIALTONE Send X2 messages and BUSY and RING BACK. Dial Tone Detection is disabled.

Answer Tone(CCITT) Sent to the DTE when the V.25/T.30 2100 Hz Answer Tone (Data or Fax) is detected. If the DTE fails to react to the code, and the modem continues to detect Answer tone, the code is repeated as often as once every 0.5 second. Busy Sent to DTE when the busy cadence is detected. The modem sends the busy b code every 4 seconds if busy continues to be detected and the DTE does not react. This allows the DTE the flexibility of ignoring what could be a false busy detection. Calling Tone Sent when the T.30 1100 Hz Calling Tone (Fax Modem) is detected. The modem assumes the calling tone is valid and sends this code only after 4 seconds of proper cadence has been detected. If the DTE does not react to this code, the code is repeated as often as once every 4 seconds. Dial Tone Sent in Voice Receive Mode when dial tone is detected after any remaining data in the voice receive buffer. The modem sends this code every 3 seconds if dial tone continues to be detected and the DTE does not react. This allows the DTE the flexibility of ignoring what could be false dial tone detection. European Data Modem Calling Tone Sent when the V.25 1300 Hz Calling Tone (Data Modem) is detected. The modem assumes that the calling tone is valid, and sends this code only after 4 seconds of proper cadence has been detected. If the DTE does not react to this code and calling tone continues, the code is sent again as often as once every 4 seconds. Bell Answer Tone Sent when Bell 2225 Hz Answer Tone (Data) is detected. If the DTE fails to react to the code and the modem continues to detect Answer tone, the code is repeated as often as every 0.5 second. Hung Up Handset Sent immediately when the modem detects that the local handset has hung-up. Quiet Sent in Voice Receive Mode after any remaining data in the receive voice buffer when the silence detection timer (#VSP) expires and the voice data has been passed to the DTE. 37 V90K56DOCATC11A AT Command Guide s t Silence Sent in Voice Receive Mode after the silence detection timer (#VSP) expires and if valid voice has not been detected (#VSS). Handset Off-Hook Sent one time when the local handset transition goes off-hook. End of Stream This code is sent to denote the end of a voice data stream. Shielded Codes (Continued) Code Sent to Modem p r Meaning Terminate Sent during Voice Transmit Mode to indicate that the DTE has finished transmitting a voice message. The Modem completes transmission of any remaining data in the voice transmit buffer before responding with the VCON message and entering Online Voice Command Mode. Cancel Sent during Voice Transmit Mode to indicate that the DTE has finished transmitting a voice message and wants the modem to discard any remaining data in the voice transmit buffer. The modem immediately purges its buffer and then responds with VCON message entering Online Voice Command Mode. Pause Sent during Voice Transmit Mode to force the modem to suspend sending voice data to the selected output device. Any data currently in the voice transmit buffer is saved until either a resume ( r), or cancel ( ), is received, in which case the data is lost. If a is received during the paused state, the modem processes it normally, and also automatically resumes transmission of the data left in the buffer (appended with ). Any other data received from the DTE while in this paused state is placed in the transmit buffer according to available space, with flow control active. Resume Sent during Voice Transmit Mode to force the modem to resume sending voice data to the selected output device. Any data currently in the voice transmit buffer is now played. 38 V90K56DOCATC11A AT Command Guide PTT Testing This facilitates testing of signal levels and provides a continuous signal when the modem is in IDLE mode. This allows the user to initiate a series of signal that are necessary for PTT approval. These signals are answer tone, carriers, modulation, and other pertinent signals. A selected test will be terminated when any keyboard character is entered. The followings are command descriptions. Note: For DTMF, the transmit level is -10dBm for low band and -8dBm for high band, inter digit delay is fixed at 70ms. All other transmit levels are adjustable according to the setting of register S91 (from -10 to -15dBm). %P00 - %P09 %P10 %P11 %P12 %P13 %P14 %P15 %P16 %P17 %P18 %P19 %P20 %P21 %P22 %P23 %P24 %P25 %P26 %P27 %P28 %P29 %P30 %P31 %P32 %P33 %P34 %P35 %P36 %P37 %P38 %P39 %P40 %P41 %P42 DTMF tone digits from 0 to 9.
