Could you, please, try the following patch (untested):

stty's "-oxtabs" seems to exist for BSD only, that's why I have added the
check. It might not be sufficient for all cases; MACOSX (which is also
BSD-like) might return another string for "uname -s". Do you know what
it returns (you run it on your local machine).

Be careful when applying the patch; I have created it on top of Tramp
2.1.19-pre.
