IP packets normally go to the tun*, and after that, if the serial line is down, ppp dials etc. So, I don't see a way to detect the PPP connection state better than using pppctl by some script. If you're not using -auto mode, but still need to detect the state of PPP (-ddial, incoming PPP), you can flag the state by creating a file in /etc/ppp/ppp.linkup and /etc/ppp/ppp.linkdown scripts (they don't run in -auto mode). -- Konstantin V.
