Re: [gpsd-users] Binary protocol using

[Anthony Stirk]

I note it *should* work (I did read the man pages) however I don't think its calculating the check sum correctly. I'm not entirely sure its creating the command correctly at all. Please correct me if I'm being dumb here (wouldn't be the first time) but the command I'm requesting isn't the one being issued to the GPS module as far as I can tell. I'm open to suggestions.

Regards,

Anthony

It already does.  That's what the control-send method is for; you give
it a payload, it wraps the load in the right checksum for the selected
device type and ships it.  This is even documented. :-)
