win32all on win95: importv win32file fails

[Marie-Claude Savoie]

Hi All,

I have a similar problem but don't know if it is related.  I had some serial
IO code that was working under W95 and above and had created it with python
2.0 and pythonwin 135.  Using the same code now with python 2.2 and
pythonwin 146 I get a problem on W95 but not on W98 or later.

I have tracked the problem down to win32file.pyd using dependency walker.
The Winsock has been updated to 2.  The error message that I get is
ImportError: DLL load failed: A device attached to the system is not
functioning.

Are there any functions that I could avoid using to get around this problem?
Could I use the win32file.pyd from build 135 and use it instead of the
win32file.pyd from build 146?

Right now I am using

 from win32file import *

Can I get around this problem by only importing the functions that I need?

I need my code to work with W95 and above, and this is causing serious
problems.

Thanks

Gordon Williams
