I use rp3 to dial up and connect to my ATT worldnet acct.
rp3 -i ppp0 will start the GUI, and I click the button to connect.
Modem connects and network is configured properly. Problem is
with GUI. It does not recognize it is now connected, and
does not show link usage. A button click again does not disconnect,
but tries again to connect.
