I think the SOCKET procedure would be your only platform independent option.
Try connecting with a reliable http host:

socket, 1, 'www.google.com', 80, connect_timeout=5, error=e

Or maybe some other creative use.

Reimar,
I thought this one is easy: Network not available -> IDL starts in demo
mode, Network available -> Flexlm finds the license and IDL starts. :-)
Ok, I am just kidding! I am afraid that I dont have the answer you are
looking for.

Greetings,
Haje

Neat; I hadn't used 'socket' before.
IDL 5.6 help says socket is only implemented on UNIX and Windows
platforms.

Does anyone know if 'socket' exists in IDL for Mac OS X? (I know OSX
is unix underneath, but am unsure if RSI considers OSX a 'unix
platform'.)

Thanks!
-Henry
