I can run the program in Eclipse and telnet successfully to a Windows host.

 

But when I export to .exe file by py2exe:

 

python gen_exe.py py2exe

 

 

File gen_exe.py:

 

from distutils.core import setup

import py2exe

 

setup(

    options = {

            "py2exe":{

            "packages": ['wx.lib.pubsub'],

            "dll_excludes": ["MSVCP90.dll", "HID.DLL", "w9xpopen.exe"],

        }

    },

    console = [{'script': ‘my_program.py'}]

)

 

When I run my_program.exe, this error is displayed:

 

UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal not in range(128)

 

at line:

 

       connection.write(username + '\r')
