What you are doing above is correct.

I just tested, using your commands;

echo -e -n "\xB5\x62\x06\x00\x14\x00\x01\x00\x00\x00\xD0\x08\x00\x00\x00\xC2\x01\x00\x07\x00\x03\x00\x00\x00\x00\x00\xC0\x7E" > /dev/serial0
echo -e "\xB5\x62\x06\x08\x06\x00\x64\x00\x01\x00\x01\x00\x7A\x12" > /dev/serial0
stty -F /dev/serial0 115200

And did a cat on serial0, filtered on RMC and it works.

pi@raspberrypi:~ $ cat /dev/serial0 | grep RMC
