The output of this sentence can be activated/deactivated according to the setting
of parameter NO (refer to table in chapter 5.1). Additional a checksum can be
applied to each sentence (MWV and MTA). This behaviour is selected by
parameter FR. If this parameter is set to 1 the checksum is appended to the end
of each sentence by use of the delimiter "*" and appears after this character as a
two digit hexadecimal value as defined in the NMEA0183 standard. The value is
calculated by XOR'ing the 8 binary data bits of each character of the sentence
between the leading "$" and the delimiting "*".
Example: $WIMTA,024,C*33
