I just dredged up a little c program that was posted to one of the mailing
lists or the newsgroup by thomasl@mit.edu back in 1995.

At that time I had 24x7 dedicated dialup access. This little daemon would
ping the default route and if the ping didn't work it would kill the pppd
daemon if it was still running. I just compiled it and named it ppp-up.

I also had a cron job that ran every 2 minutes. If it didn't see that pppd
was running, it would restart it. I had the script keep a log of how often
it restarted the daemon.

I could probably also dredge up the cron script, but I will have to boot
my 486/33 NetBSD 1.0A system which is sitting in the corner at this moment.

The ping daemon is at:
