Why do you want to do this?  Are you asking about writing Devanagari
vertically rather than horizontally?  If that is what you want, you
should be looking at mark-up such as is found in cascading style sheets
(CSS).  It is an important issue for CJK and Mongolian, and there have
been questions as to what is needed for Indian scripts.  (There's also
an antiquarian interest for historical scripts, such as Phags-pa and
even Egyptian - moves are afoot to support the hieroglyphic script as
plain text.)
