The number of rings a Remote Access Service (RAS) server's modem allows before answering is easily configurable.

A network administrator may have RAS running on a Windows NT Server or Advanced Server and want to share the phone line between another device (a fax machine, for example) and the RAS modem. This article describes how to set the number of rings the modem waits before answering.

To edit the MODEM.INF file found in WINNT\SYSTEM32\RAS, find the section relating to your modem, and change the value on the COMMAND_LISTEN line (the last line in the example below) to the number of rings you want before the modem answers.

NOTE: You must re-boot the NT server before the change will take effect.
