Setting Modem Connection Preferences

• 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 utilized if their rate of transfer can be stepped down to a maximum of 2400 bps (TAP specification). However, some newer modems can not be made 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.
