Requset a valid result during INIT_ROM process through serail port 0

I connected tini with PC via a LAN cable, while I could not grap a packet 
by using ethernet tools.  Could anyone offer me a valid result during the 
init process, I doubt that I had not passed the rom and network init.  I 
use a realtek PHY chip and using the phy address #1, I can read and write 
the chip's register with "eth_readmii" and "eth_writemii" when I set phy = 
#1.  However, I am confused about the INIT process.  I do not know how TINI 
work when it INIT.
Thanks a lot!!
My Result as below:

DS80C400 Template Project
About to perform an init of the rom...
DS80C400 Initialization Library Version 13

Dallas Semiconductor DS80C400 Socket Demonstration

Set network parameters result: 0
Network params result: 0
IP    : 192 168 110 244
Subnet: 255 255 255 0
Prefix: 16
Gate  : 192 168 110 1
Create a network socket handle: 0
Connect a TCP socket to host result: 70
Create a network socket handle: 1
Connect a TCP socket to host result: 70
Close socket result: 0
Close socket result: 0

The program will now freeze.

My code as below:
    printf("DS80C400 Template Project\r\n");
/*
 * Perform an init of the rom
 */
    printf("About to perform an init of the rom...\r\n");
	init_clearXSEG();
	init_copyivt();
	init_redirect();
	init_clearSystemRAM();
    init_mm(RAM_START, RAM_END);
	init_km();
	init_network();
	init_eth();
	init_sockets();
	init_tick();
	task_genesis(ROM_SAVESIZE);
	init_enableinterrupts();
	task_settickreload(RELOAD_18_432);  // Necessary for accurate timing.
    clear_param_buffers();

    // let's print out a little version information...
	printf("DS80C400 Initialization Library Version %d\r\n", init_version());
/*
 * Allocate Static IP address, Get Network config params
 */    
    printf("\r\nDallas Semiconductor DS80C400 Socket 
Demonstration\r\n\r\n");
	do_static();
    network_config();
/*
 * Try build a socket and connect to server, send sample data
 */
    for (i=0;i<100;i++)
    {
        data1[i] = i;
     //   data2[i] = i;
    }
    for (i=0;i<18;i++)
        address.sin_addr[i] = 0;
    address.sin_addr[12] = HOST_IP_MSB;
    address.sin_addr[13] = HOST_IP_2;
    address.sin_addr[14] = HOST_IP_3;
    address.sin_addr[15] = HOST_IP_LSB;
    address.sin_port = 33333;

    socket_handle1 = socket(0, SOCKET_TYPE_STREAM, 0);
	printf("Create a network socket handle: %u\r\n", socket_handle1) ; 
    result = connect(socket_handle1, &address, sizeof(address));
	printf("Connect a TCP socket to host result: %u\r\n", result);
    socket_handle2 = socket(0, SOCKET_TYPE_STREAM, 0);
   	printf("Create a network socket handle: %u\r\n", socket_handle2) ; 
    result = connect(socket_handle2, &address, sizeof(address));
	printf("Connect a TCP socket to host result: %u\r\n", result);
//	send(socket_handle1, data1, 55, 0);

    result = closesocket(socket_handle1);
	printf("Close socket result: %u\r\n", result);

	result = closesocket(socket_handle2);
	printf("Close socket result: %u\r\n", result);


	printf("\r\nThe program will now freeze.\r\n");
	while(1)
	{

	}
