• Modem Initialization String (ATE0). The default string is ATE0Q0V1X4F1.
    • (E0) Command Echo Off
    • (Q0) results code
    • (V1) verbal results code (as opposed to numeric)
    • (X4) result codes for some specific phone/modem conditions (see modem manufacturer for details)
    • (F1) local echo off
  • COM Port. Select the port to which your modem is attached.
  • Baud Rate. Select the speed (measured in bits per second) at which the serial port communicates with the modem.
    Note: Newer modems (e.g. 56K versions) may be used if their rate of transfer can be stepped down to a maximum of 2400 bps (TAP specification). However, some newer modems cannot be adjusted to transfer below 9600 bps even though you may use an initialization string that specifies a lower rate of transfer.
  • Data bits. Select the type of data bit transmission used to communicate with the selected port. 6, 7, or 8 data bits.
  • Parity. Select the type of parity expected by the modem connected to the selected serial port.
  • Stop. Select the stop bits used to communicate with the selected port. 1 or 2 data bits.
