-The 'VALUES' params separated by a space indicate the order of the values in the CSV string. The 'NULL' value indicates that the value is not going to be sent, but discarded when the CSV comes into the program. The 'NEWLINE' param indicates the character that separates the CSV strings, the usage of '\n' is not currently supported. The 'SEPARATOR' param indicates the character that separates the values in the CSV string. The 'BAUDRATE' param indicates the baudrate of the serial port. The 'UDP_PORT' param indicates the port of the UDP server. The 'SERIAL_PORT' param indicates the serial port to use.
+The 'VALUES' params separated by a space indicate the order of the values in the CSV string. The 'NULL' value indicates that the value is not going to be sent, but discarded when the CSV comes into the program. The 'NEWLINE' param indicates the character that separates the CSV strings, the usage of '\n' as a NEWLINE can be achieved via the 'LF' symbol and the '\r\n' via the 'CRLF' one (ex: NEWLINE=LF). The 'SEPARATOR' param indicates the character that separates the values in the CSV string. The 'BAUDRATE' param indicates the baudrate of the serial port. The 'UDP_PORT' param indicates the port of the UDP server. The 'SERIAL_PORT' param indicates the serial port to use.
