I have Python 2.4.4 and 3.1.3 on my Windows 7 machine. I would like to use PySerial.
I heard that it was built-in, so I tried import serialin both versions. Both called Import Error.
Then I downloaded the win32 installer from this page . I ran it and installed for 2.4.4. (He said he found it in the registry.) I did not have the opportunity to upgrade to version 3.1.1.
Then I got the following error in 2.4.4:
>>> import serial
Traceback (most recent call last):
File "<pyshell#0>", line 1, in -toplevel-

import ctypes
ImportError: No module named ctypes
I look up ctypesand see that he was a bullet with 2.5.5. Good.
Download ctypesand run python setup.py install. (2.4.4.)
I get the following:
