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,

# Makefile -  to make a modified terminfo entry for "linux".

# 113 = 0x71 = 0x01 (set hardware cursor invisible)

I didn't reply on Usenet because I am not yet setup to do so.

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.
