ntpdc> help addserver
function: configure a new server
usage: addserver [ -4|-6 ] addr [ keyid ] [ version ] [ minpoll|prefer ]

If you look at the code in ntpdc/ntpdc_ops.c:doconfig(), it shouldn't be
hard to figure out that a) the usage line is actually correct in this
respect, i.e. there is no way to pass in a maxpoll value, and that b)
the ntpdc<->ntpd protocol actually seems to allow for it - and then it's
just a SMOP to implement the functionality in ntpdc...
