…ndows - Properly handle `None` for `self._write_timeout` by using `win32.INFINITE`. - Use `WaitForSingleObject` to wait with timeout before calling `GetOverlappedResult`. - If timeout occurs (`WAIT_TIMEOUT`), cancel the pending write using `CancelIoEx`. - Avoid blocking indefinitely on `GetOverlappedResult` by passing `wait=False`. - Raise `SerialTimeoutException` if the write is incomplete or canceled. This prevents the serial write from hanging indefinitely when the device becomes unresponsive.
