Somewhat following a suggestion on netbsd-help (or netbsd-users?)  and
somewhat hacking on my own, I've pieced together a "pppd daemon".  I guess
that would be "pppdd".  ;-) 

#!/bin/csh

while (1)
    set p=`/usr/local/bin/newping -o -c 3 198.93.80.102 |& grep -c route`
    if ( $p != 0 ) then
        # It's down!
        echo "IP link down - restarting PPP" >> /var/log/ppp
        set p=`cd /proc; grep -l '^pppd' */status`
        if ( $p != "" ) then
                kill `cat /var/run/ppp0.pid`
        endif
        sleep 3
        stty -f /dev/tty00 clocal
        pppd
    endif
    sleep 900
end


Now I'll explain the quirks... newping is a slightly modified version of
the regular ping, where the diff output was posted by the guy who
suggested this on the list.  I think that in the convoluted way I'm using
it, the regular ping would work just as well.  I found that if my ppp
connection was down, each ping attempt would yield "no route to host"...
so use a very ugly kludge and simply check to see if "route" is returned
in the ping output.  If so, it restarts the ppp connection, after writing
a very non-informative line to /var/log/ppp (I've meant to have it write
the date & time, too, but I haven't gotten around to it).

This whole thing is completely a result of cut-and-paste work, so I'd
gladly accept suggestions on how to better go about this task.  At least
it somehwat works in its current state -- it's better than I expected of
myself!

HTH,
