Dial-up Networking

  • Article

Microsoft® Windows® CE .NET implements dial-up networking with Remote Access Service (RAS) and Point-to-Point Protocol (PPP). Dial-up networking allows a Windows CE–based device to access network resources from a remote location. First, a connection is established with the remote computer, and then the Windows CE–based 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 Windows CE–based 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. Windows CE can connect to a remote access server using direct serial and infrared as well as dial-up.

Windows CE–based applications using RAS can link to Coredll.lib to resolve RAS API entry points, determine the proper method for a device build, or link to the Windows XP RAS API set (Rasapi32.lib).

Windows CE .NET introduces support for RAS custom scripting and AutoDial. RAS custom scripting enables developers to customize the process of establishing a connection. AutoDial enables a Windows CE device to automatically attempt a new dial-up connection when the current connection fails.
