Specify initialization commands

Updated: February 7, 2008

Applies To: Windows Server 2008

You can use this procedure to send additional configuration commands to your modem before it dials the phone number.

The commands you enter here are sent after the standard initialization commands for the selected modem. This enables you to change the modem behavior or configuration as required by your communication software or for communication with a service provider. For more information about the commands recognized by your modem, see the manufacturer's documentation.

Any user account can be used to complete this procedure.

  1. In Control Panel, click Hardware and Sound, and then click Phone and Modem Options.

    noteNote
    In Windows 7 and Windows Server 2008 R2, open Control Panel. In View by, click either Large icons or Small icons. Click Phone and Modem.

  2. In the Phone and Modem dialog box, on the Modems tab, click the modem that you want to configure, and then click Properties.

  3. On the Advanced tab, in Extra initialization commands, type the commands that you want sent to the modem when it is initialized. Type the commands exactly as they must be sent, with no extra spaces or characters. The AT prefix is unnecessary.
