RAS AutoDial (Windows CE 5.0)
RAS AutoDial enables a Windows CE device to automatically attempt a new dial-up connection when the current connection fails. For example, if a user is connected to a server on the corporate network with an 802.11 NIC and roams out of the 802.11 network, AutoDial senses the lost connection and dials the default host server to reconnect.
AutoDial is triggered when a connection is lost. It will not attempt a connection if there is any form of connectivity, either public or private. Nor will it attempt a connection if RAS is attempting to make a connection.
The AutoDial DLL, named Autoras.dll, provides the autodial functionality to dialer applications. An AutoDial-compatible dialer communicates with the AutoDial DLL through a message queue.
Windows CE includes a test application for RAS Autodial. This sample application is located in the %_WINCEROOT%\public\common\oak\drivers\netsamp\autoras\test directory and can be used either from the Platform Builder for Windows CE IDE, or from the command line.
The following topics explain how to write an AutoDial-compatible dialer and how enable a default AutoDial connectoid:
