Hi, I am using embedded Visual C++ on WinCE with Winsock API calls and
want to detect if my Ethernet card is connected to a switch or not
without actually making a connection to another socket. A bit like how
your computer 'knows' when connected to a switch, without actually
requiring DHCP, etc. (just plug in an RJ45 and the on-board link light
comes on). Thanks for any help. Mark.

The link state should be provided in the dwOperStatus:
