Dear all,  
I m facing problem with sample codes in TCP/IP on RCM 3400 target board with Dynamic C 9.21 version. I tried pingme.c,pingyou.c, pingled.c could not get any response on the command prompt.How I can identify socket is initialized and open.Any ideas on what I m forgetting?  
I change the IP address of my pc to 10.10.6.102 and RCM3400 board is with 10.10.6.101.  
Netmask is 255.255.255.0.
