I want to check the Ethernet port to see if a Cable is connected. If it is, I will open a socket and communicate with the client. If it is not connected, then I will just run an internal program to process I/Os.

Take a look at the pd\_havelink() function to see if you’re physically connected, and ifpending() for the status of the connection (e.g., getting a lease from the DHCP server and not completely up).

Thank you!  
That worked perfectly. I was trying to do it with a variety of status checks, but couldn’t find one that worked for me.  
Best regards,
