Well, the obvious thing to do is to look at the status of the link:
# ifconfig ppp0
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
inet 192.109.197.137 --> 139.130.136.129 netmask 0xffffffc0
If it's UP and has two addresses, then you're connected. If you're
using user PPP, this will be tun0, not ppp0.
