The TCP_SERVER issue

Dear all

I am working on Device MCF52235 in which I am using Ethernet as communication channel. Along with the communication I need to detect the Proximity card in weigand mode. The problem I am facing is whenever the Port is connected the TCP communication is ON , I am not able to process the Proximity card reading. I need to read 50uSec pulse. I am using the Coldfire_Lite_tcp_server code as is with out modification. I am calling the card reading function in TK_ENTRY .

When the TCP communication is not in progress and socket is disconnected the card reader works fine. But once the socket is connected and tcp communication is ON card doesnot read.

TK_ENTRY(tk_emgtcpsrv)

{

   int err;

   while (!iniche_net_ready)

      TK_SLEEP(1);

   err = freescale_tcp_init();

   if( err == SUCCESS )

   {

      exit_hook(freescale_tcp_cleanup);

   }

   else

   {

      dtrap();                                                                   // emghttp_init()  shouldn't ever fail

   }

   for (;;)

   {

            ReadCardReaders();

      freescale_tcp_check();                                 // will block on select

      tk_yield();                                                    // give up CPU in case it didn't block

      if (net_system_exit)

         break;

   }

   TK_RETURN_OK();

}

Please let me know whether I am calling the function in right place?
