Description

Basic import of ExceptionResponse or ModbusException does not work. I found closed issue about three weeks old (#1906). I tried to reinstall pymodbus (does not help), also I tried this simple code snippet on windows and got exact same output.

pymodbus init defines

all = [ "ExceptionResponse", "Framer", "ModbusException", "pymodbus_apply_logging_config", "version", "__version_full__", ]

and both our examples as well as our tests import these without problems, however be aware, this is with the current version. Version 3.5.4 is relative old, and I am not sure if the symbols exported have changed.

As I suspected in v3.5.4 init defines:

all = [ "pymodbus_apply_logging_config", "version", "__version_full__", ]

Please use the appropriate documentation when looking for how the code works.
