Yes.  As noted at the top of the ":help t_SI" paragraph:

  Added by Vim (there are no standard codes for these):

http://invisible-island.net/xterm/ctlseqs/ctlseqs.html has information
on the sequences necessary to control this behavior with xterm.  For
example,

  " Switch to underline on insert
  let &t_SI="\<Esc>[4 q"
  " Back to block when leaving
  let &t_EI="\<Esc>[2 q"

Setting it interactively works for me when running in xterm.  I'm not
sure why it wouldn't work, since Vim sends this every time it
enters/leaves insert mode.
