[lwip-users] PPPos does not detect modem disconnection

[vinimac]

Hi all,

I am simulating a signal loss by removing the antenna from the modem and it
keep sending packets to a server using TCP socket. After remove the antenna,
the function send wont fail() and error number is not set too. 

I was expecting TCP layer to detect the lack of TCP ACK or PPP should have
some timeout? 

I am running Lwip 2.0 from ESP32 SDK.
