Re: [gpsd-users] Earthmate and the Zodiac Driver

[Scott Nolde]

My cvs tools weren't built when I built my last world for FreeBSD so I'm fixing that to get portdowngrade to work properly.  As for git, no, I'm not familiar with it.  I do have -D4 debug info from before if it might help (below):

The Earthmate reliably worked before the 3.x change.

Thanks for the reply.  I think it was 2.96 when it last worked, and perhaps the one before that.  I've not yet had the chance to downgrade the port.

Well, first, tell us what version of gpsd was working for you.

Do you know git well enough to run a bisection?  If we could pin down
what commit caused the problem I could probably solve it very rapidly.
