There are several methods, but none of them really dependable, except to test for the accessibility of a known online resource (PING, HttpGet, etc).

The one I use is

DECLARE INTEGER InternetAttemptConnect IN WinInet.dll INTEGER
?INternetAttemptConnect(0)=0

This one initiates a DUN dialog if needed, and waits until the connection succeeds or fails. It has worked dependably for me, but others have reported inconsistencies.
