@ -208,7 +208,7 @@ By default, VFS uses simple functions for reading from and writing to UART. Writ
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``.
