Have you read the ctypes docs? http://starship.python.net/crew/theller/ctypes/tutorial.html You have to read the Microsoft docs too, search what dynamic libraries to use and what functions to call. Study the example I posted, you have to call these functions using ctypes: (openfile, readfile, writefile...) Don't know if somebody has implemented serial access using ctypes as to post an example, read the docs, first you need to understand how ctypes work -for that you should know or learn what C variable types are and understand it almost a little bit, then the codeproject example will come in handy- otherwise could be hard to code... Though any ctypes example handling file or stream data may help you. Though pyserial uses ctypes too, so you could have a look to the sources. The differences are you have to use straight windows api calls, and pyserial calls a helper library wich should use windows api's for windows platform. I have to code serial access too in the next weeks, but don't have the time now to get my hands in it. If you are not in hurry I could post an example when done. Gonzalo.
