Nope. There is no inherent X11 support. You need to use the Display
Postscript Extension, implement a text rotation extension, find a
library which implements rotated text, or rotate it yourself. To
rotate it on the client side, requires that you first be able to
read the glyph definition into a bitmap, which is then easily rotated
by 90� by simple special-case logic, and then drawn using PUT_IMAGE
to the screen.

| Re/ .1:
When you say "draw character strings vertically," do you mean with the
individual characters upright
L
i
k
e
t
h
i
s
?
Or do you mean with the characters rotated?
If you want the characters upright, you just have to figure out where
to position them, and draw the characters individually. If you want to
rotate the individual characters, then you will have to do as Fred
suggests in .1. Display PostScript is the easiest route.
