推荐答案

答案终于简单：

 Socket client = new Socket(_IP, PORT);

 oStream = new PrintStream(client.getOutputStream(), true, "UTF-8");

 oStream.println("-------------------------------------------------\r\n");
 oStream.println(" NAME     : DEMO CLIENT\r\n");
oStream.println(" CODE  : 00000234242\r\n");
oStream.println(" ADDRESS   : Street 52\r\n");
oStream.println(" Phone : [phone]\r\n");
oStream.println("-------------------------------------------------\r\n");

oStream.flush();

oStream.close();
client.close();
