ftpclient ascii transfer mode not the same as ascii ftp from unix box

I am trying to use the ftpClient class to ftp a file in ascii mode to a windows machine.
 But, the file size is different than when I use Hummingbird ftp or unix ftp.
 I guess, other ftp command creates an additional character at the end of each line (carriage return or line feed) for windows systems. I think that the ftpClient does not do that. The file created by ftpClient is smaller than the ones created by humming bird or unix ftp.

Here is my sample java code:
import java.io.*;
import java.util.*;
import sun.net.ftp.FtpClient;
import sun.net.TelnetInputStream;
public class FtpUpload {
  static String ftpaddress;
  static String ftpusername;
  static String ftppassword;
  static String ftpfilename;
  static String ftptransfermode;
  static String ftpremotefilename;
  static String ftpdirectory;
public static void main(String[] args) {
try {
   ftpaddress      = args[0];
   ftpusername      = args[1];
   ftppassword      = args[2];
   ftpfilename      = args[3];
   ftptransfermode = args[4];
   ftpremotefilename      = args[5];
   ftpdirectory      = args[6];
   System.out.println(ftpaddress);
   System.out.println(ftpusername);
   System.out.println(ftppassword);
   System.out.println(ftpfilename);
   System.out.println(ftptransfermode);
   System.out.println(ftpremotefilename);
   System.out.println(ftpdirectory);

    FtpClient ftpClient = new FtpClient();
    ftpClient.openServer(ftpaddress);
    ftpClient.login(ftpusername, ftppassword); // login
    if(ftptransfermode=="A")
      {
      ftpClient.ascii(); // change to ascii mode transfer
      }
    else  
     {
    ftpClient.binary(); // change to binary mode transfer           
     }
     
     if(ftpdirectory!="")
      {
       ftpClient.cd(ftpdirectory); // change directory
      }
 
    BufferedOutputStream out = new BufferedOutputStream(ftpClient.put(ftpfilename));
    BufferedInputStream in = new BufferedInputStream(new FileInputStream(ftpfilename));
    int b = -1;
    while ((b = in.read()) != -1) {
       out.write(b);
    }
    in.close();
    out.close();
    ftpClient.closeServer();
  } catch (Exception e) {
    e.printStackTrace();
    System.exit(1);
  }
}
}

Any suggestions??

Thanks
