Since use of OT is being discouraged on OS X, I was wondering what
the recommended way of managing PPP connections was these days.
Mac OS X 10.3 introduces a new API, SCNetworkConnection, that lets
you manage dialup connections properly. It's very snazzy. Give it a
try. There's no documentation (yet), but the comments in the header
<SystemConfiguration/SCNetworkConnection.h> are pretty helpful.
Prior to 10.3 all of your choices are problematic. If you can limp
along with OT, that's probably best. Beyond that, you need to
investigate PPPLib. Here's a (slightly edited to accommodate
SCNetworkConnection) quote from my previous postings on this topic.
You can use the "ppplib" code from the Darwin PPP sources. You can
find a quick tutorial on this on the following web page.
<http://www.cocoadevcentral.com/tutorials/showpage.php?show=00000026.php>
There's also been several discussions of this on the MacNetworkProg
mailing list. If you follow the links from the mailing list's web
page, you will find a searchable archive of that material.

The drawback to using "ppplib" is that it's not officially supported
by Apple. Here's a statement that the manager of our network
engineering team posted to the list just recently.
Let me emphasis the PPPLib code does not defines an API (Application
Programming Interface). This is just a sample code that is part of
Darwin but it is not part of Mac OS X. Apple is not making any
guaranty the PPPLib code does actually work now or will work in
future releases of Mac OS X.
Obviously, we are aware of the usefulness of PPPLib and we will try
to keep PPPLib working.
Use at your own risk!

Apple is aware of these problems and has introduced (in Mac OS X
10.3) a new, supported API, SCNetworkConnection, to address them.
You should only use PPPLib on Mac OS X 10.2.x and earlier. To
ensure long-term compatibility, you must use the new API where
available.
