Cisco DialOut Utility, Release 2.0, is a software utility that allows you to send faxes or use communication software from any workstation connected to a NAS. The Cisco DialOut Utility adds one or more virtual communication (com) ports to your Microsoft Windows workstation. These com ports are used to represent com ports on the NAS. Individual workstations do not require modems, offering substantial savings in a large network and increased savings as the network grows.
The Cisco DialOut Utility is designed to run on Windows 95, Windows 98, and Windows NT. The Setup program detects the operating system on which it is being used and installs the appropriate files.
The Cisco DialOut Utility software converts com port calls from the fax or Internet communications package into network calls that are sent to the NAS.
For example, when a user presses a key in a communications package such as HyperTerminal, the communications package sends the character to the Cisco DialOut Utility driver module:
The Cisco DialOut Utility driver module is a special version of the standard serial device driver.
The Cisco DialOut Utility lets you configure and monitor the com ports. The utility runs minimized in the active icon area of the taskbar at the bottom of the screen. To maximize the utility, double-click the icon.
The Cisco DialOut Utility consists of the network interface program, a standard Windows program that connects the driver layer to the network via TCP/IP; and one of the following modules, depending on the version of Windows you are using:
All modules are in the Windows virtual memory space, and all network layer resources are released when the program is shut down by the user. Because the Cisco DialOut Utility does not terminate and stay resident, no memory below 640K is needed.
New features in Release 2.0 of the Cisco DialOut Utility include support for:
Additionally, the meanings of the LED colors and sequences have changed.
The Cisco DialOut Utility complies to the protocols defined in RFC 2217, Telnet Com Port Control Option. This RFC is available from the Internet Engineering Task Force (IETF).
Cisco DialOut Utility is Year 2000 compliant, but the applications with which it is used must also be compliant.
The Cisco DialOut Utility requires the hardware and software specified in the following sections.
The Cisco DialOut Utility requires the following hardware:
