Calling a Desktop Computer's Modem from your Mobile Device
With a modem installed on your mobile device, you can call a modem attached to your desktop computer to connect to Microsoft ActiveSync. Connect by modem when you need to synchronize information while you are away from your desktop computer and your desktop computer is not connected to a network on which you have a remote access server. If your network has a remote access server, you can skip these instructions and follow the Microsoft ActiveSync Help topic "Connect to ActiveSync Using a Modem."
Warnings:- These instructions are approximate steps intended for experienced users only. Depending on the system configuration, other steps may be required, or some of the steps outlined may not be necessary. If you are not familiar with network component installation and configuration, you should consult your system administrator.
- Installing and configuring Remote Access Service (RAS) and Dial-up Networking (DUN) to work with ActiveSync may disable other types of ActiveSync connections, such as serial cable and cradle. Automatic baud rate detection will also be disabled.
- If you disable serial connection, RAS and DUN will not be disabled. You must separately disable network and RAS connections under Connections Settings on the File menu
- These procedures may interact with your existing network configuration (for example, dial-out modems) or require removal of proxy software to work properly.
- The instructions for Windows 2000 are for Beta 3. The final product may require slightly different steps.
Before you begin:- Set up a partnership between your device and desktop computer using a serial cable, cradle, or infrared connection. For more information about setting up a partnership, see Microsoft ActiveSync Help.
- If your computer is running Windows NT 4.0, you need to install the Remote Access Service (RAS). RAS is installed as a part of all Windows 2000 installations.
- If your desktop computer is running Windows 95, you need to install Dial-Up Networking Upgrade (DUN) 1.3 or later which is available at: http://www.microsoft.com/Windows95/downloads/. The following procedures will not work with DUN 1.2.
- Install an internal or external modem for your desktop computer and configure it for general use as instructed in Windows Help or your modem instructions.
- Install an internal modem, PC Card modem, or external modem for your device.
