I am posting via BT DUN through my PPC-6601 and it is working well. Thank you. I do have another two questions.

Does the BT DUN connection use the BT Modem to connect? I am quite sure it does. (My HP tablet, Windows XP SP2, uses an HP BT patch which changes the MS BT stack back to the Widcomm BT stack, ). At one point around the first 3500 build I could query the BT modem from the Control Panel/Phones and Modems/Modems/"Bluetooth Modem"/Properties/Diagonostics/Query and get a response. Now I can not get a response but DUN works. Any ideas?

Do you think AT commands sent via the BT serial port are able to access and control dialing the phone?

Thank you
