To connect your Windows Mobile Pocket PC, first install the Signal application on your device:
When installation completes Signal will be available on your device under Start > Programs > Signal. To connect, start the application on your Pocket PC and tap the connect button.
In most cases Signal will be able to find and connect to the server application automatically. If it cannot, try entering the IP address of your computer into the connect field of the Pocket PC application. The IP address is shown as the first four numbers of the web address in the Signal application window on your computer. For example, if the web address shown is http://192.168.1.2:3569/ enter 192.168.1.2 into the Pocket PC client’s connect field and tap the connect button.
If you have trouble connecting your device, please see the connection troubleshooting guide.
