Dial-up Networking Overview

The Dial-up Networking feature for Microsoft® Windows® CE .NET is implemented with Remote Access Service (RAS) and the Point-to-Point Protocol (PPP). Dial-up Networking allows a device to access network resources from a remote location. First, a connection is established with the remote computer, and then the device, or client, can upload and download files.

RAS is a component that connects a client to a host computer, known as a remote access server. A device running RAS connects to a remote access server using PPP. PPP is a set of industry standard framing and authentication protocols that enable remote access. A device can connect to a remote access server using a direct serial, infrared, or a dial-up connection.

Applications using RAS can link to Coredll.lib to resolve RAS application programming interface (API) entry points, to determine the proper method for a device build, or to link to the Windows XP RAS API set (Rasapi32.lib).

RAS custom scripting allows you to customize the process of establishing a connection. AutoDial enables a device to automatically attempt a new dial-up connection when the current connection fails.
