    XDemo23: Echoes all data (include "23") to specific clients.

    23  -> Any command will be accepted.
    
    This demo Uses VcomSendSocket to echo all data (including "23") 
    to specific clients.
    Xserver will echo all data (inclued "23") to client.

    Hardware: 7188E 

    Refer 7188e\TCP\Doc\[Big5|Eng|Gb2312]\Vxcomm.htm 
          7188e\TCP\Xserver\Xserver.htm
          7188e\TCP\Xserver\Function.htm   
    to get more information.
	
	Because the kernal of Xserver used InstallCom() function.
	Please use printCom1() instead of Print() if you want to send formatted output from COM1.

    Received data is stored in the TCPREADDATA structure.

    The TCPREADDATA is declared as below:    
    
        Type define t_TCPReadData{

            int Socket;
            int Length;

    user can get the following message:
    p->Socket : The index of datas. the socket number that receives the command
                when the user function wants to return a message to the client, 
                just use the socket to send data.
    p->ReadUartChar : the buffer stored the command data(include "23")
                      Maximum length of p->ReadUartChar is 32767 bytes.
                      so, the data needs triming "23".      
    p->Length : the command data length(include the two byte "23")
