Fellas, he has a fix.
If this is a terminfo description bug too, then somebody please report it.

I have a fix for this problem,

    Gentlemen, in good old tty mode, outside of X windows,
    I have in .bashrc
    if test $DISPLAY$EMACS; then :; else
        #VGA-softcursor.txt says to get red non-blinking block prompt
        echo -e '\033[?17;0;64c'
    fi

One must create an edited terminfo entry, so run the attached
Makefile from your ~/.terminfo directory,

Re: emacs doesn't restore one's non X windows prompt

[Dan Jacobson]

I got another view on this which i paste below.  Anymore views please
send directly to the list. I noticed the problem but I only use this
part of the system once a year hence...

I'd say it isn't a terminfo bug.  If you want cnorm etc. to restore a
modified cursor, then you have to modify them; that's all there is to
it.

emacs doesn't restore one's non X windows prompt

[Dan Jacobson]

Gentlemen, in good old tty mode, outside of X windows,
I have in .bashrc
if test $DISPLAY$EMACS; then :; else
    #VGA-softcursor.txt says to get red non-blinking block prompt
    echo -e '\033[?17;0;64c'
fi

however, after entering emacs, one gets a prompt blinking at a rate
that says "I've got to go to the bathroom now, please".

The unfairness in our story is that after exiting emacs, our solid red
cursor that says "Ommmm" is replaced by the emacs 'where's the john,
urgent' prompt for the remainder of our shell session.

Ok, maybe that was the original login prompt. In that case I sort of
apologize to emacs...
