Hello Rani,
There are 2 methods that I know of:
1. Can GPSD use this NMEA stream? If it is possible then you can then just
use GPSD. Not sure if GPSD supports NICs.
2. Develop INDI driver to read and process the NMEA stream. This is a lot
of work of course, but if the GPSD option does not work then this is the
only option.
