Hi Folks
Now that I've got a computer ready to be a time server, I am now
fiddling about with my GPS modules, checking that they are working and
the like.
As I have yet to build and interface board for my Trimbles (requires a
very fine pitch IDC connector, which is on backorder), I am testing

Ah, thanks. That must be in another chapter - the wretched PDF is split

I had a similar problem a while ago.
I wrote a simple python hack to compute the checksum. The manual probably
has an example you can test it on.
I sent individual commands with things like this:
echo -e -n "\$PSRF103,0,0,0,1*24\r\n" > /dev/tty

I haven't got around to writing an oncore driver yet. There was one in
the works but the pe

gpsd can't
