Updated: February 7, 2008

Applies To: Windows Server 2008

You can use this procedure to configure data communication settings for your modem. Settings include the speed by which your computer communicates with the modem device, the protocol and flow control used, and whether to compress data by using hardware or software.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

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

  2. On the Modems tab, click the modem that you want to configure, and then click Properties.

  3. On the Advanced tab, click Change Default Preferences.

  4. On the General tab, under Data Connection Preferences, change the setting for Port speed, Data protocol, Compression, or Flow control.

  • These values are usually set correctly when the modem is installed.
