uIP做TCP客户端出现 got reset, aborting connection等问题的可能原因

AMeT

这几天在用原子的mini+enc28j60+uIP做以太网通信的学习，单片机做客户端，PC端用NodeJS写了服务器，用于打印接收的数据（我本来在服务器上开的3000端口，这就是问题所在）

var net = require('net');
var HOST = '192.168.1.101';
var PORT = 1400;
// Create a server instance, and chain the listen function to it
// The function passed to net.createServer() becomes the event handler for the 'connection' event
// The sock object the callback function receives UNIQUE for each connection
net.createServer(function(sock) {
    // We have a connection - a socket object is assigned to the connection automatically
    console.log('CONNECTED: ' + sock.remoteAddress +':'+ sock.remotePort);
    // Add a 'data' event handler to this instance of socket
    sock.on('data', function(data) {
   console.log('DATA ' + sock.remoteAddress + ': ' + data);
    // Write the data back to the socket, the client will receive it as data from the server
    sock.write('You said "' + data + '"');
    });
    // Add a 'close' event handler to this instance of socket
    sock.on('close', function(data) {
    console.log('CLOSED: ' + sock.remoteAddress +' '+ sock.remotePort);
    });
}).listen(PORT, HOST);
console.log('Server listening on ' + HOST +':'+ PORT);[/mw_shl_code]

结果实验的时候ping/web server/tcp server全无问题，唯独client在服务器端显示连接然后就没有下文

我用wireshark抓包得到
client->server SYN
      <-           SYN,ACK
      ->           ACK
后面用于数据传输的数据包根本就没有出现（显示为PSH，ACK），一段时间后串口输出一个关于ip header length 的问题或者 got reset, aborting connection.事实上在wireshark里没有出现IP报头长度不符合20bytes的数据包，也没有哪一方产生RST
后来死马当活马医，把单片机程序和服务器端口都改成1400

似乎是uIP不支持太大的端口号？顺便求讲解一下具体的原因
