[ntp:questions] ntp version 4.2.7p257-o

Thanks for pointing out the nodebug/debug confusion for the p257
binaries for Windows.  I've renamed the .zips to repair.

I suspect the rest of your problem will be fixed soon once a release
comes out that has Juergen Perlinger's improved emulation of line
discipline serial input in the Windows port of ntpd.  In the meantime,
you can potentially work around it by cranking your serial line rate
to the minimum 4800 bps, which may require configuring the GPS to emit
fewer sentences each second.

As for ownership of the NMEA driver, quite a number of us have had our
fingers in it, including Juergen Perlinger, Hal Murray, Venu Gopal,
Danny Mayer, myself, and others whose names don't appear in commits
because they submitted patches integrated by Harlan or someone else.

Cheers,
Dave Hart
