Hi all, I've just noticed bug 1999, "Remove PMOTG output sentence from Type-20 driver".
I've found a use for the PMOTG message output, which I've started to use as a heartbeat from ntpd in my bespoke nav software which forwards RMC messages to the ntpd via a virtual serial port on Windows. I find this to be a useful mechanism to determine if the panic threshold has been exceeded and ntpd has aborted, as my software can generate an alert to the user that they should set the system clock to UTC, at least within the tolerance of the panic threshold. Whilst I agree that ntpd probably doesn't need to send this by default, and also have no imminent concern as we're using the new stable release 4.2.6p4 which still sends the PMOTG messages at the poll interval, I'd like to know that ntpd can still be built with this mechanism enabled for refclock 20 in future versions. I note that NMEA_WRITE_SUPPORT is defined in refclock_nmea.c and wonder if instead of the option being buried there, it could instead be enabled more conveniently (for Windows ports and regular builds) at build time without resorting to patching code. I also appreciate that this is a real corner case and that I'm a little fish in a big pond, so I could understand if there was no desire to accomodate my needs, but it would be good to know what the future holds in this regard before I pack and ship my nav sw.
