So, no change.

I did what David  & Chris hinted at.  I added "ifdown eth0" to the
beginning of the pon script & added "ifup eth0" to the beginning of the
poff script which works, but only as root.  As user I get:

sh: ifconfig: command not found 

 when running pon/poff.  This is ok with me since losing eth0 connection
to the internet is a rare (knock on woody) occurance.

So, it does look like eth0 has to be up and running before stopping ppp.
