How to send NMEA sentences to a configurable receiver?

[GPS_man]

I know which NMEA sentences I want to send to my GPS-Receiver but I have never used the GPSD Deamon. All I found out how to do is polling to the NMEA sent by the receiver.
My problem is: the PPS output of my Garmin is disabled by default. I would like to set it on enabled.
I have the NMEA sentence I need but I don't know how to send it.

I would be very glad if someone is able to answer my question.

Which model of Garmin GPS do you have?

My device is a Garmin 16x LVS

The user manual (technical spec.) for the 16x here :-
https://support.garmin.com/support/manuals/manuals.htm?partNo=010-00258-62&language=en&country=GB

Shows MNEA sentences that can be sent to the 16x and NMEA sentences that can be sent from the 16x.

It looks like GPALM, PGRMI, PGRMC, PGRMC1 and GPRMO can be sent to the 16x and 13 NMEA sentences can be sent from the 16x (only 5 are sent from default), GPRMO is used to select which sentences are sent and it is also used to enable / disable NMEA output from the 16x

The PPS output is enabled / disabled by the PGRMC NMEA sentence (sent to the 16x), see the user manual section 4.1.3

Thank you for your reply. I already read the documentation of these configuration sentences. But my main problem is that I don't know how how to send them using GPSD.

Do you need to send the setup configuration sentence to the 16x using GPSD?, as this only needs to be sent once, couldn't you connect to the 16x using an RS232 terminal emulator?

Yes, that's what I did in the end. But I'm still wondering how it works with GPSD..
Does someone know?
