Refclock 38 (the Hopf 6021 serial driver) was redundant with a mode of refclock 8, the parse drive, that also supports the 6021. I also removed the Hopf 6039 refclock due to a proprietary-driver dependency. This takes us just over 60% of the NTP Classic code removed. -- <a href="http://www.catb.org/~esr/">Eric S. Raymond</a>
