Customize PdaNet to connect to your ISP
Below are steps to customize PdaNet to dial your own ISP

Step 1: Click on the tray icon and select "Settings" from the context menu

Step 2: In the Settings dialog, check "Advanced" and confirm.

Step 3: To dial your own ISP over voice minutes other than the default data network, you need to make sure you have a Dialup Networking Entry for your ISP (which currently binds to your local modem), you can select it from the list box. PdaNet will automatically bind it to the (Treo) PdaNet Modem when you connects. Make sure you click "OK" to save the changes.

Step5: Launch PdaNet from Treo to initiate the connection. DO NOT launch it from the dialup entry on the PC side directly.
