Hi Gary,
Currently I was setting baud rate to 4800bps and using ' gpsd -b'.
I am getting output when I use 'cat /dev/ttyS0 '.
Still need to connect Data In pin of GPS?
Thanks,
Lokesh
Yo lokesh!

Obviously no data Out means nothing can talk to your GPS to change
settings. That will be a PITA as you need to change things like
the serial speed. 4800bps is just not good enough.
If you have upped the GPS speed on another host, and use 'gpsd -b'
then no data out would not cause this.
Too low a speed could cause this (input buffer overflow). Or voltage
mismatch on the Data In can cause this.
Which is why I suggested you try a USB GPS to eliminate those as
causes.
