Older devices sometimes do not implement NMEA0183 correctly by omitting CRC. It would be nice if there would be way to make parser ignore CRC mismatches for certain sentences.
We are retrofitting 2005 built vessel that has GPS device sending sentences without CRC. Our navigation engineers say it is not very rare to have older devices like that. So for example devices reading/receiving NMEA0183 sentences have sometimes option to disable CRC checks because of this sad reality.
