I'm implementing an "all in one" PPP configuartion and dial-up tool for a

one problem,.....when I execute the dialup, I don't get back any status
message back on OTNotifyUPP function,......so my application has no idea if
or when it has successfully opened (or closed) a connection.
I know that is it possible to get status information as "internet connect"
actually reports all the information for the PPP connect started/closed by
my application.
Because you mention "Internet Connect", I'm going to assume that this
is on Mac OS X.
There is a known bug <rdar://problem/3080214> with the OT/PPP API on
Mac OS X that prevent you from getting all of the OT/PPP events.
However, you should get *some* events. Have you made sure to enable
event delivery using I_OTGetMiscellaneousEvents?
If the existing events don't satisfy your requirements, you can get
PPP events using "ppplib". Here's something that I posted to the
list a while back.
You can use the "ppplib" code from the Darwin PPP sources. You can
find a quick tutorial on this on the following web page.

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!

Manager,

Apple is aware of these problems and intends to rectify them,
probably by releasing a new, CF-friendly, PPP API in a future major
release of Mac OS X.
