Thank you Kaled for your interest. The reason I want to do this using Dial Up Networking is that there is provision in there to detect dropped connections, and to re-connect.
I was hoping the answer lay in something fairly simple like using the Internet connection wizard, but adding in the nstsh connection script (see above) at some point - something like using an adsl connection where there is no phone number, but code like *99## instead.
Unfortunately I am using Windows 7 which tries to do everything for you and doesn't have places where you can add in stuff like XP used to have.
