I've fixed the problem by using the 8.1.2 binary off the 3.3 CD #2.

I think you may be confused as to the purpose of rc.conf. It is a list
of environment variables, which are included several times within the
various rc.* files during boot time. It shouldn't invoke programs
directly. Loads of default values are stored in /etc/defaults/rc.conf,
which are then overridden by the values you set in /etc/rc.conf. You
should never need to change /etc/defaults/rc.conf as this is updated
every time the operating system is upgraded.
That said, I start ppp from my rc.conf file using the following
This will cause the following command to be executed at the appropriate
time during the boot up sequence and will hopefully avoid the false
starts your experiencing.
ppp -auto -nat -quiet papchap
Note that -alias is and alias for -nat and you can change papchap to
demon by using the following statement in your rc.conf:

I have seen some talk about this in the past, and apparently there is a
correct way to close a connection, but with some connections this
doesn't happen, perhaps because the dial-up line gets dropped. But TCP
has some long timers, being _very_ resilient to delay, and after a
minute or so will drop the connection unilaterally.

Firstly, you should keep records so that you can limit your exposure to
huge phone bills. If you allow it to dial up during peak time, and
someone sends you a huge e-mail (most users don't even know they're
doing it sometimes), and the punts are running slow that day, you could
clock up =A320 or so bill during the day with your end working just fine.=
You need to decide what rules you want to impose then see how you can
achieve them. =
Also you might want to look at the various ppp filters, which determine
which types of packets can cause a dial-up and which types of packets
can hold the line up. I haven't used these (yet) so I can't advise.
