The above works functionally, but when I telnet from windows and run command ls, the output is a mess: 

..
plit
    str
       strref
             swig.txt
                     system
                           tax.perl
                                   test.gif
                                           test_graph
                                                     test.txt
                                                             time
                                                                 tk
                                                                   tmp
                                                                      tty
                                                                         typeglo
b
 url
    use
       vt100
..

The above is what I get after run the command ls.

Seems windows prompt can't display vt100 correctly, how to fix this issue?
