  • Page 19: At Command Set

    AT Command Reference Manual 3. AT COMMAND SET 3.1 AT COMMAND GUIDELINES The basic AT commands used to control modem operation are defined in this section. These commands are summarized in Appendix A. All these commands may not be available in a specific product depending upon supported data rates and modes.

  • Page 20: At Command Set

    3.2 AT COMMAND SET The modem will respond to the commands detailed below. Parameters applicable to each command are listed with the command description. The defaults shown for each configuration command are those used in the Rockwell factory profile 0. 3.2.1 AT Commands A/ - Re-execute Command The modem behaves as though the last command line had been re-sent by the DTE.

  • Page 21: Cn - Carrier Control

    Cn - Carrier Control This command is included for compatibility only, and has no effect other than returning a result code. The only valid parameter is 1. Result Codes: n = 1. ERROR Otherwise. Dn - Dial This command directs the modem to go on-line, dial according to the string entered and attempt to establish a connection. If no dial string is supplied, the modem will go on-line and attempt the handshake in originate mode.

  • Page 22: En - Command Echo

    Wait for silence: the modem will wait for at least 5 seconds of silence in the call progress frequency band before continuing with the next dial string parameter. If the modem does not detect these 5 seconds of silence before the expiration of the call abort timer (S7), the modem will terminate the call attempt with a NO ANSWER message.

  • Page 23: Fn - Select Line Modulation (Rc144 Models Only)

    Fn - Select Line Modulation (RC144 Models Only) This command selects the line modulation according to the parameter supplied. The line modulation is fixed unless Automode is selected. This command interacts with the S37 and the N command. The parameter value, if valid, is written to S37 bits 0-4.

  • Page 24: Hn - Disconnect (Hang-Up)

    Hn - Disconnect (Hang-Up) This command initiates a hang up sequence. This command may not be available for some countries due to PTT restrictions. The modem will release the line if the modem is currently on-line, and will terminate any test (AT&T) that is in progress.

  • Page 25: Mn - Speaker Control

    Mn - Speaker Control This command selects when the speaker will be on or off. The parameter value, if valid, is written to S22 bits 2 and 3. Speaker is always off. Speaker is on during call establishment, but off when receiving carrier. (Default.) Speaker is always on.

  • Page 26: P - Set Pulse Dial Default

    P - Set Pulse Dial Default This command forces pulse dialing until the next T dial modifier or T command is received. Sets S14 bit 5. As soon as a dial command is executed which explicitly specifies the dialing mode for that particular call (e.g., ATDT...), this command is overridden so that all future dialing will be tone dialed.

  • Page 27: T - Set Tone Dial Default

    T - Set Tone Dial Default This command forces DTMF dialing until the next P dial modifier or P command is received. The modem will set an S- Register bit to indicate that all subsequent dialing should be conducted in tone mode. Note that the DP command will override this command.

  • Page 28: Xn - Extended Result Codes

    Xn - Extended Result Codes 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).

  • Page 31: Yn - Long Space Disconnect

    Yn - Long Space Disconnect This command enables/disables the generation and response to long space disconnect. The parameter value, if valid, is written to S21 bit 7. Disables long space disconnect. (default.) Enables long space disconnect. In non-error correction mode, the modem will send a long space of four seconds prior to going on-hook.

  • Page 32: At& Commands

    3.2.2 AT& Commands &Cn - RLSD (DCD) Option The modem controls the RLSD output in accordance with the parameter supplied. The parameter value, if valid, is written to S21 bit 5. &C0 RLSD remains ON at all times. &C1 RLSD follows the state of the carrier. (Default.) Result Codes: n = 0 or 1.

  • Page 33: Gn - Select Guard Tone

    &Gn - Select Guard Tone The modem generates the guard tone selected by this command according to the parameter supplied (DPSK modulation modes only). The parameter value, if valid, is written to S23 bits 6 and 7. &G0 Disables guard tone. (Default for US models.) &G1 Disables guard tone.

  • Page 34: Mn - Asynchronous/Synchronous Mode Selection

    &Mn - Asynchronous/Synchronous Mode Selection This command determines the DTR operating mode. The modem treats the &M command as a subset of the &Q command. &M0 Selects direct asynchronous operation. Note that the command sequence &M0\N0 selects normal buffered mode, but the command sequence \N0&M0 selects direct mode. This is because the \N0 command is analogous to the &Q6 command.

  • Page 35: Qn - Sync/Async Mode

    &Qn - Sync/Async Mode This command is an extension of the &M command and is used to control the connection modes permitted. It is used in conjunction with S36 and S48. (Also, see \N.) NOTE: When the &Q0 to &Q4 command is issued to select the mode, the subsequent connect message will report the DCE speed regardless of the W command and S95 settings.

  • Page 36: Rn - Rts/Cts Option

    &Rn - RTS/CTS Option This selects how the modem controls CTS. CTS operation is modified if hardware flow control is selected (see &K command). The parameter value, if valid, is written to S21 bit 2. &R0 In sync mode, CTS tracks the state of RTS; the RTS-to-CTS delay is defined by S26. In async mode, CTS is normally ON and will turn OFF only if required by flow control.

  • Page 37: Display Current Configuration And Stored Profiles

    &V - Display Current Configuration and Stored Profiles Reports the current (active) configuration, the stored (user) profiles, and the first four stored telephone numbers. The stored profiles and telephone numbers are not displayed if the NVRAM is not installed or is not operational as detected by the NVRAM test during reset processing.

  • Page 38: Wn - Store Current Configuration

    &Wn - Store Current Configuration Saves the current (active) configuration (profile), including S-Registers, in one of the two user profiles in NVRAM as denoted by the parameter value. This command will yield an ERROR message if the NVRAM is not installed or is not operational as detected by the NVRAM test.

  • Page 67: Audiospan And Dsvd Commands

    3.9 AUDIOSPAN AND DSVD COMMANDS AudioSpan and DSVD are two technologies that allow simultaneous voice and data operation using a Rockwell modem connected to a telephone line. AudioSpan and DSVD implementations differ in the manner that voice and modem data are combined.

  • Page 68: Vls = X - Voice Line Select

    Notes AudioSpan audio quality is dependent upon modulation mode, data rate and telephone line quality. Some guidelines are: Higher quality telephone lines provide better audio quality than impaired telephone lines. A lower data speed with audio provides better audio quality than higher data speed with audio. For example, a ML288/9600 connection will be audibly superior to a ML288/14400 connection.
