Thanks to all that replied to my question. I addopted the solution
suggested by Brian Somers <brian@awfulhak.org>: set an alias on the login
shell and use it to start ppp. The shell exits properly when ppp stops:

Add to the end of /etc/csh.login:
# to start PPP
set tt = `tty`
alias ppplogin 'exec /usr/sbin/ppp -direct ${tt:t}'

Add to the end of /etc/profile:
# to start PPP
tt=$(tty)
alias ppplogin='exec /usr/sbin/ppp -direct ttyd0 ${tt##*/}'

Antonio
