Applications which use the UART driver can instruct VFS to use the driver's interrupt driven, blocking read and write functions instead. This can be done using a call to the ``esp_vfs_dev_uart_use_driver`` function. It is also possible to revert to the basic non-blocking functions using a call to ``esp_vfs_dev_uart_use_nonblocking``.
VFS also provides an optional newline conversion feature for input and output. Internally, most applications send and receive lines terminated by the LF (''\n'') character. Different terminal programs may require different line termination, such as CR or CRLF. Applications can configure this separately for input and output either via menuconfig, or by calls to the functions ``esp_vfs_dev_uart_set_rx_line_endings`` and ``esp_vfs_dev_uart_set_tx_line_endings``.

如果应用程序使用 UART 驱动，则可以调用 ``esp_vfs_dev_uart_use_driver`` 函数来指导 VFS 使用驱动中断、读写阻塞功能等。您也可以调用 ``esp_vfs_dev_uart_use_nonblocking`` 来恢复非阻塞函数。
VFS 还为输入和输出提供换行符转换功能（可选）。多数应用程序在程序内部发送或接收以 LF (''\n'') 结尾的行，但不同的终端程序可能需要不同的换行符，比如 CR 或 CRLF。应用程序可以通过 menuconfig 或者调用 ``esp_vfs_dev_uart_set_rx_line_endings`` 和 ``esp_vfs_dev_uart_set_tx_line_endings`` 为输入输出配置换行符。
