This is the Gnome applet I use for modem access. After adding a user to the "dip" Unix group they can use this applet to dial the modem, display transfers, and to hangup. Under properties I had to change the connect and disconnect commands to be pon and poff rather than pppon and pppoff (which don't exist -- perhaps this is a "problem"). The newer Potato version of the applet had the defaults correct.
