Nit exactly. The only recent change to the PPS logic that wasn't from
you was a change by Miroslav Lichvar intended to handle longer PPS
intervals.
It had an error which I fixed. After the fix, I lived-tested it with the
GR-601W and it seems to work.
You mentioned in a previous mail that autobauding is failing for you.
I dimly recall that you've had this problem before and it was a local
config issue. That code has been stable/working for a long time.
