+Forwarding valid NMEA-GGA messages to the NTRIP broadcaster is required for receiving VRS streams. Thus, in case your serial connected device is not capable to provide them, the alternative for VRS streams is a 'Manual' simulation of an initial NMEA-GGA message. Its contents is based on the approximate (editable) latitude/longitude from the broadcaster's source-table and an approximate VRS height to be specified.
