Applies To: Windows Server 2008

You can use this procedure to configure your modem to use hardware-based data compression.

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

To specify hardware data compression

  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. In Data Connection Preferences, in the Compression list, click Enabled or Disabled.

Additional considerations

Some communications programs provide efficient software-based data compression. If you are using a program that provides software-based data compression, turning off hardware-based data compression can often provide the highest data throughput speed.
