It seems that your shell profile executes stty(1) even
for non-interactive shells.  That is wrong.  Make sure
that you shell profiles and rc files do not call stty
or produce any output for non-interactive sessions.
Such output confuses scp.

That is, when you enter this command:
$ ssh tony at admin true | hd
then you should not get any output from it.  If you do
get output, you need to fix your shell profile on the
remote host.

Best regards
