When opening the CON device the underlying CreateFile call needs to use either GENERIC_READ or GENERIC_WRITE access, but not both. Currently opening for writing fails as follows:
>>> open('CON', 'wb', buffering=0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [WinError 87] The parameter is incorrect: 'CON'
If self->writable is true, it should set `access = GENERIC_WRITE`, not `access |= GENERIC_WRITE`.
This only applies to CON. It's normal to open CONIN$ and CONOUT$ with both read and write access, and WindowsConsoleIO handles that correctly.
