Epoch vs Emacs : cursor-in-echo-area

I recently wrote an emacs-lisp function that reads in a password
without echoing.  This function uses the function call:

        (setq cursor-in-echo-area t)

to move the cursor from the buffer window to the minibuffer window
(actually the echo area -- same physical location as the minibuffer).

When I evaluate my function from EMACS (epoch -nw), everything works
fine.  When I evaluate the same function from EPOCH (using X Window),
it still works except that the cursor never moves to the echo area.

Does EPOCH use the global variable cursor-in-echo-area in the same
way that EMACS does?

Also, as a test, I set cursor-in-echo-area to `t' in EPOCH.  The cursor
did not move out of the buffer window.  But when I created a *Buffer List*
[C-x C-b] and moved the cursor to that window, the cursor did not behave
correctly.  It stayed at the end of the first line.  The cursor also stayed
at the end of the line in RMAIL mode.

Could anyone explain what is going on in EPOCH when cursor-in-echo-area
is `t'.  Also, is there a way to move the cursor to the echo area in 
EPOCH?
