 SPEAKERPHONE MODE

      8.1 OPERATION WITH
      COMMUNICATION SOFTWARE

      The full-duplex speakerphone operation can be used by
      running a communication software application which
      supports the Rockwell Speakerphone function. Follow the
      instructions of the respective application package.
      Alternatively, speakerphone operation can be used by
      manually issuing AT command to the modem as
      described in Section 9.2.

      8.2 MANUAL OPERATION USING
      TERMINAL MODE

      8.2.1 Originating a Voice Call in
      Speakerphone Mode

      1. Invoke the terminal mode in your communications
      package.
      2. Enter AT and make sure that OK is returned. Enter
      AT&F to reset modem configurations to default values. All
      instructions to the modem are communicated through AT
      commands. For example, ATD is the AT command for the
      modem to dial; all AT commands start with the "AT"
      characters. Refer to the RCV144ACF/SP Modem
      Designer's Guide for the list and descriptions of the AT
      commands that the RCV144ACF/SP target board
      supports.
      3. Enter AT#CLS=8#VRN=0#VLS=6 and press the
      return key. The modem should respond with OK. This will
      initialize the modem for speakerphone mode.
      4. To dial, enter ATDTnnnnnnn where nnnnnnn is the
      phone number of a remote party. The modem will report
      VCON at the completion of dialing and indicate
      speakerphone is on.
      5. To hang up, issue ATH.

      8.2.2 Answering a Voice Call in
