打开端口23以使用Node.js读取数据

Question

On my windows laptop there is a program with a TCP/IP server on port 23. I can open it with a telnet terminal and see the data streaming. I need to get that data into a node.js program I'm working on. Should be easy but I haven't found any code examples. Searches come up with lots of examples of how to make a server on port 23 with Node.js.

Thanks

This is a high level TCP/IP socket implementation in node. See: Node net API

var net = require('net'),
    port = 23, 
    host = 'localhost',
    socket = net.createConnection(port, host);

socket
  .on('data', function(data) {
          console.log('received: ' + data);
      })
  .on('connect', function() {
          console.log('connected');
      })
  .on('end', function() {
          console.log('closed');
      });
