rn reads news from the local machine, rrn uses the NNTP protocol to a
remote news server machine.

This is the wrong thing to do.  Rn uses the termio(7) style ioctls
just fine.  The only catch is that the latest patchlevel of rn (pl 44,
which I assume you are using) has a bug in the Configure script, where
it tries to figure out whether to use termio ioctls or stty/gtty.
Apply the patch below.

(The bug (IMHO) is in the use of test at line 1284. "test something"
doesn't run "something" and check its exit status, it checks that
"something" is a nonempty string...)
