Hi, I'm using LWIP 1.4.1 and I'm facing an issue with "brutal" raw socket disconnection.
Imagine the following scenario: - Create a TCP_PCB listener (server) - On connection from a remote host (a Windows PC), accept it, with all callbacks - Now, I remove the Ethernet cable from my application - I also exit (brutally) the remote client application - Now, I wait 1 minutes and connect back the Ethernet cable - LWIP never signals the connection is lost, not the state of the PCB tells me (Still ESTABLISHED)! How to detect this kind of disconnection ? Thank you Fred
