247    * Emacs on a tty switches the cursor to large blinking block.
248    
249    This was reported to happen on some GNU/Linux systems which use
250    ncurses version 5.0, but could be relevant for other versions as well.
251    These versions of ncurses come with a `linux' terminfo entry, where
252    the "cvvis" capability (termcap "vs") is defined as "\E[?25h\E[?8c"
253    (show cursor, change size).  This escape sequence switches on a
254    blinking hardware text-mode cursor whose size is a full character
255    cell.  This blinking cannot be stopped, since a hardware cursor
256    always blinks.
257    
258    A work-around is to redefine the "cvvis" capability so that it
259    enables a *software* cursor.  The software cursor works by inverting
260    the colors of the character at point, so what you see is a block
261    cursor that doesn't blink.  For this to work, you need to redefine
262    the "cnorm" capability as well, so that it operates on the software
263    cursor instead of the hardware cursor.
264    
265    To this end, run "infocmp linux > linux-term", edit the file
266    `linux-term' to make both the "cnorm" and "cvvis" capabilities send
267    the sequence "\E[?25h\E[?17;0;64c", and then run "tic linux-term" to
268    produce a modified terminfo entry.
