Auto disconnect dial-up

[Lyall Pearce]

Not being an expert at Win XP, I want to have my modem
disconnect when my screen saver kicks in.

I gather I could set an inactivity timeout on the dialup
but I figure this would not occur because the computer in
question will probably have an e-mail program running
(which polls for new messages), AIM (which I assume sends
traffic back and forth) and MSN (which I also assume sends
traffic back and forth)

I figure the screen saver would be the ideal way to auto
disconnect.

Any suggestions?

Thanks in advance.
