gpsd -V returns
gpsd: 3.4 (revision 3.4)


Interestingly, 

echo '?POLL;' | nc localhost 2947

does not produce the error, so I think the problem is in the perl
module.

However the line in GPSD3.pm that sends the poll request is just:

$self->socket->send(qq(?POLL;\n));

which looks fine to me and indeed seems equivalent to the echo test.


To solve the immediate problem I've written a workaround: a script that
uses watch() until the first tpv, then dies returning the results. This
emulates polling well enough for my immediate uses but isn't ideal.

Thanks -

Andy
