Art:
That would be helpful.... I looked in my archives for the code and could not
find it.
Thanks.

Carl:

I had sent you that simple program that monitors the QTCPxxxx message queue
and extracts the IP address assigned from the message received when the
dialup connection is made.

Would you like to see that CLP again?  It's not an API call, but it does
work.

Peter:
I have not seen a command that lets you extract the IP address assigned by
the remote DHCP server.  I am willing to bet there is an API for it.  Having
never written code using an API, I was hoping to avoid that.  It seems that
there should be a rather simple solution to this problem.  We can do it with
CISCO routers by allowing the router to sense the primary T1 is down and
using a secondary default route to connect over an ISDN route.
Any one know if there is an API to extract the address assigned during a
dial up PPP session?

Hi Carl,

Is there any way to determine the IP address assigned by your ISP's DHCP
server after you connect?  If so, I'd think you could use that to update the
default route when you dial up.
