Hello, I'm wondering how to detect that a TCP connection has been closed? Also, if a connection were to get disconnected via a power outage (simulated by disconnecting the ethernet cable from the device)? Currently I transmit a byte of data every 15secs of no activity and when I get an error I close the connection. I need a better way since the application on the other end has to process the byte that I'm sending which causes problems. I'm using lwIP with the xilinx tools (S3ADSP1800A eval board). Just a note, I'm using lwIP in non blocking mode so the read command either returns -1 or the number of bytes read. Any help would be appreciated.
Regards, Gurpal Gill
