Is there any point to it without the matching kernel driver?
Tom added echo functionality to the LPT PPS client. (not yet in the
kernel but we can test...)
Maybe you can test, I have no way to test.
So if we can have ublox data via USB, we can have PPS/ECHO via LPT.
I'm lost, what does USB have to do with anything?
The ublox module https://www.csgshop.com/product.php?id_product=240 has
USB via e.g. this breakout board
https://www.csgshop.com/product.php?id_product=239; USB provides power
and data connection.
Else, we have to enable some NMEA messages on the ublox and do
similar with NMEA and PPS clocks.
I'm still lost... But that is not a problem. Go forth, test, code,
repeat. When it works for you, and the PPS patches are in the kernel,
tell us how it works and we'll patch ntpd.
OK great news!
Kind regards,
Udo
