Power management settings: the modem can bring the computer out of power states S1, S2, S3, S4 as long as the BIOS is configured accordingly.


The Windows XP modem drivers on the included CD are version (date 10/8/2004). They were not installed since newer drivers are available here with premium access.

Installed Windows XP drivers version 2.1.54. This driver supports audio pass-through to the sound card, i.e., instead of hearing the phone audio through the modem's speaker, the sound is playing through the sound card.

The CD also contains:

  • An OEM version of the Panda Software's FaxTalk Communicator SE 4.5 fax and voice telephony application.

After installation, the system hung intermittently. Also, if a phone is connected to the modem's second connector, the line is not released by the modem after a call. Uninstalled the application.

  • FaxTalk NetOnHold - if your ISP supports the V.92 protocol, then you can receive and place voice calls while the modem is still connected to the Internet. A similar application "Modem On Hold" is available from the modem site. Neither modem-on-hold application was tested.

  • Windows XP component "Fax Services" allows  sending and receiving faxes. Install from Control Panel -> Add or Remove Programs -> Add/Remove Windows Components. Besides sending and receiving faxes the fax service can be configured to monitor incoming calls which displays a balloon text with the caller ID number.
