I have a Motorola T720 and the mobile phone tools software with a USB cable. I am having no luck connecting to my ISP. I am using Motorola USB Modem as a driver and the XP Dial Up Networking. It does not seem that the phone actually dials but I get an error 678, Could not connect to remote computer. I called the Software maker, Motorola, and Cingular but none of them can seem to help. Does any body have any ideas on how I can get connected?
