http://www.eecis.udel.edu/~mills/ntp/html/drivers/driver20.html states:
"The driver will send a $PMOTG,RMC,000*1D<cr><lf> comand each poll
interval. This is not needed on most GPS receivers because they
automatically send $GPRMC every second, but helps a Motorola GPS
receiver that is otherwise silent. NMEA devices ignore commands they do
not understand."
That should surely be a flag, not a default. To send out sentences by
default that you know most units do not understand is irresponsible.
There is not guarentee that all others devices will ignore it. It is
also an ugly kludge which in 20 years should have received a better
solution.
(And are there any Motorola devices that still behave that way?)
Agreed, it should not be sent by default.
However, this does still not explain the difference I see between 4.2.7p97
and 4.2.7p206.
Cheers,
