I am using LPC1764 + TLK105 to make serial to ethernet(cice-versa) converter. I use TCP/IP stack of keil . In this project a am using tcp socket to receive data from ethernet and then send it to UART. Also to send Data receive from UART to Ethernet i am using tcp socket. I use this converter in server mode. But during transmit from Etheenet to UART and in reverse direction tcp socket automatically aborted without any request from client side. So please guide me to diagnose this problem.
What debugging have you done and what have you so far concluded?
At the very least I would hope you've used a sniffer to determine the precise traffic.
I have used keil in built debugger and found that control reaches at the call function's tcpabort case automatically without any request of either tcp_close or tcp_abort.
if i understood you well ,Presently i have not used any sniffer like wireshark or any other still now. So will you pleas guide me on this issue?
You can use wireshsrk to examine the traffic. An abort would typically be generated by the othe other side sending a RST.
