Finding and interacting with Dialup connections ?

Hello,

I would like to be able to show in a combobox a list of dial up connections
the user can use to connect to the internet. Then when they choose a
connection and click on dial or something similar, I would like the program
to dial up to the internet.

Also, if anyone could tell me how to recieve http responses from a perl
script. I would call a url and need to be able to read a response.

Regards

Nick
