as a workaround do

ping -c 3 <other side> || (kill -INT `cat /var/run/`;sleep 30;pppd call <nameoflink>)

but yes it is a but in NetBSD since at least 1.5.1 (oldest i used).

bad news is that com/puc driver or pppd itself is even more broken on 1.6 
and 2.0. i use separate machine as router for 12 pppd links with 
115-921kbps speeds
