[lwip-users] about lwip socket() and connect()??

[xcb]

lwip-users:
        I use lwip's ppp and a wireless moderm run in window,(gprs)link is up,i 
want to test socket connect to a server(IP:61.154.4.200 ,port :5906 listen),As 
connect() is return ERR_OK,but server dont accept any ip connection 
immediately, when execute send(), server machine can accept an IP 
connection(61.154.4.200),and recv "test tcp socket",that code is down,hep me to 
rosolve it

                        sprintf(strIPaddr,"61.154.4.200");
                        memset(&ListSvAddr,0,sizeof(ListSvAddr));
                        ListSvAddr.sin_family=AF_INET;
                        ListSvAddr.sin_port=htons(5906);
                        ListSvAddr.sin_addr.s_addr=inet_addr(strIPaddr);
                        
                        sock = socket(PF_INET, SOCK_STREAM, 0);
                        iNet = connect(sock,(struct sockaddr *)&ListSvAddr, 
sizeof(ListSvAddr));
                        
                        sprintf(sendStr,"test tcp socket!!!");
                        send(sock,sendStr,strlen(sendStr),0);
