Greetings
I saw same sort of question in the Discussion list but I didnt get the
answer properly.
I have ported the TCP/IP stack it is running from FLASH no redboot. When I
ping from other windows machine to my boards ip address the ping is
resulting in 60 or some times 50% packet loss.
* I have not enabled any prints or debug messages.
* But when I see in ethreal each packet is replied.
* I dont know which TCP/IP stack I am using old or new.How to know this???
Suggesstions please....
With regards
Khasim..
