Subject: Agent/UDP recv callback not happening

hi all,

        I am new to ns. I like to simulate a UDP server and UDP client.

On Receiving the request from the client, the server has to send back the 
response.  I tried to incorporate in my TCL files:

 "Agent/UDP interproc recv {from data}"

But there is no call to this tcl routine. In the code, there is condition 
checking as PACKET_DATA

 else if (pkt->userdata() && pkt->userdata()->type() == PACKET_DATA)

How set the packet type to userdata?

Please, help for the same with any guidelines/pointers to any link.

thanks in advance.
regards,
stp.
