Due to DMA-based transfers, the rx buffer can receive a large amount of data at once. The previous character-by-character processing approach was inefficient. Modify character-by-character read to block read of the entire buffer. This improves throughput and reduces CPU overhead, especially for high-speed serial communication or other DMA-based transfers.
