  • Page 3: Introduction

    INTRODUCTION This manual covers configuration and operation of all V.34 and V.32bis external and rack mount models. Since many features discussed in this manual are optional, it is important to verify the specific configuration of your device before proceeding with installation and configuration. It is suggested that you use the AT&V command to verify the capabilities of your device.
  • Page 4 DUMB Next to the RS-232-C connector is a two pin header. When the pins of this connector are MODE not connected (default), the modem operates in smart mode. When they are connected, the modem operates in dumb mode. For more detail, please refer to the dumb mode section of this manual.

  • Page 5: At Command Set

    AT COMMAND SET Command Guidelines The basic AT commands used to control modem operation are defined in this section. Under AT operation, the modem performs autobaud, autoparity and autolength functions on each header entered. The autoparity and autolength facilities can detect 7 or 8-bit characters of even, odd, or no parity with one stop bit. 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.
  • Page 6 AT? - Read Selected S-Register This command reads and displays the selected S-Register. A - Answer The modem will go off-hook and attempt to answer an incoming call if correct conditions are met. Bn - CCITT or Bell When the modem is configured to allow either option, the modem will select Bell or CCITT modulation for a line speed connection of 300 or 1200 bps according to the parameter supplied.
  • Page 7 execution of this parameter, the modem handshakes. & Wait for credit card dialing tone before continuing with the dial string. If bong is not detected within the time specified by S7, the modem will abort the rest of the sequence. Dial pause: the modem will pause for a time specified by S8 before dialing the digits following the ",'".
  • Page 8 In - Identification The modem reports to the DTE the requested result according to the command parameter. Reports product code. Reports a pre-computed checksum. Reports "OK". Reports firmware revision (VX.XXX) model code. Reports OEM defined identifier string in Hayes compatible binary format. Reports Country Code parameter.
  • Page 9 Sn - Read/Write S-Register The modem selects an S-Register, performs an S -Register read or write function, or reports the value of an S-Register. Establishes S-Register n as the last register accessed. Sets S-Register n to the value v. Reports the value of S-Register n. T - Set Tone Dial Default This command forces DTMF dialing until the next P dial modifier or P command is received.

    Soft reset and restore stored in profile 0. Soft reset and restore stored profile 1. AT& COMMANDS &Cn - RLSD (DCD) Option This command controls the RLSD output in accordance with the parameter supplied. &CO RLSD remains ON at all times. &C1 RLSD follows the state of the carrier.
  • Page 11 &Ln - Leased Line Operation This command selects dial up or leased line operation. &L0 Selects dial up operation. &L1 Selects leased line operation. &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.
  • Page 12 mode, CTS acts according to V.25bis handshake. &R1 In sync mode, CTS is always ON. In async mode, CTS will only drop if required by flow control. (Default) &Sn - DSR Override This command selects how the modem will control DSR. &S0 DSR will remain ON at all times.

    &X2 Internal clock from DCE synchronized with carrier from remote modem. &Yn - Designate a Default Profile Selects the user profile that will be used after a reset. &Y0 Profile 0. &Y1 Profile 1. &Zn - Store Telephone Number The modem can store up to four telephone numbers. &Zn=x Where n = 0 to 3 and x = dial string.
  • Page 14 192 characters. 256 characters. \Bn - Transmit Break to Remote In non-error-correction mode, the modem will transmit a break signal to the remote modem with a length in multiples of 100 ms according to parameter specified. If a number in excess of 9 is entered, 9 is used. \Fn - Set Answer or Originate Mode In dial operation the answering modem typically assumes answer responsibility and the calling modem assumes originate responsibility.

    Clear data buffers and send break to remote modem. Same as 0. Send break to remote modem immediately. Same as 2. Send break to remote modem in sequence with data. Same as 4. (Default) The third case is where a break is received from a remote modem during a non-error corrected connection: Clears data buffers and send break to the DTE.

    These commands are extremely useful when installing modems on remote equipment that cannot issue the AT commands necessary for autobaud to occur. In such cases, it is possible to dial into the modem and remotely configure all parameters, including character format and DTE bit rate. - Enable/Disable Remote Configuration When remote configuration is enabled, the modem will respond to a standard 3 character escape sequence from the calling modem.
