I think it has a problem. Hard to say if you don't tell us more.
rlogin to the remote machine (using your password), and run a command
like `w' to see what appears as the remote hostname there:
j@uriah 51% w
12:58AM up 10 days, 1:26, 5 users, load averages: 1.50, 1.39, 1.29
USER TTY FROM LOGIN@ IDLE WHAT
j p1 :0.0 15Nov96 1:11 -tcsh (tcsh)
j p3 :0.0 15Nov96 1:12 tail -f /tmp/releaselog
j p4 :0.0 8:19PM 1 elm
j p5 :0.0 16Nov96 32:15 -tcsh (tcsh)
j p7 localhost 12:58AM - w

That's what you also need in your .rhosts. Don't forget that .rhosts
files are best kept at mode 0600; they are silently ignored if they
are writable by somebody else than the owner or root.

I assume you run the csh and have some stty command in your .cshrc.
rsh or rcp sessions don't have an associated tty, hence the stty
fails. Simply protect it by:
if ($?prompt) then
stty <whatever you want>
... <other things you only want while logged in interactively>
endif
(The csh variable `prompt' is only set for interactive shells.)
