Expand description

@brief Set the line endings to sent to specified UART

This specifies the conversion between newlines (‘\n’, LF) on stdout and line endings sent over UART:

  • ESP_LINE_ENDINGS_CRLF: convert LF to CRLF
  • ESP_LINE_ENDINGS_CR: convert LF to CR
  • ESP_LINE_ENDINGS_LF: no modification

@note this function is not thread safe w.r.t. writing to UART

@param uart_num the UART number @param mode line endings to send to UART @return 0 if successed, or -1 when an error (specified by errno) have occurred.
