From time immaterial, personkind has searched for a way to stop that
dad-dratted blinking cursor on PCompatible machines. I tried
everything, but every TSR turn-off-the-cursor-and-put-a-replacement-in
program didn't work with something in my system, be it NANSI.SYS or
something else. Then, late, late one night as I was perusing the
Video Seven V7VGA Tech Ref I stumbled onto a revelation. The Video
Seven engineers had built in HARDWARE SUPPORT for a non-blinking
cursor!!! Joy... rapture!! The program V7CURS exploits this far-
sightedness; needless to say, its for V7VGA chip VGAs ONLY, as far as
I know that includes the FastWrite VGA and the VRAM VGA.
V7CURS sets the cursor to non-blinking, XOR mode. XOR mode allows you
to see what's under the cursor. Some will be disappointed to learn
that I make no attempt to regulate the size of the cursor, this is
because lots of programs change it and if I try to stop them, I'm back
into a complicated TSR again. V7CURS is simple: just stop the
blinking and allow one to see under the cursor (especially important
if its full block size).
This is a "terminate-and-stay-resident" program that takes up
approximately 350 bytes. It can be unloaded with TSR utilities, such
as the excellent MARK/RELEASE.
USAGE
Just type V7CURS to load. Of course, you can put this in your
AUTOEXEC.BAT file to use it all the time. Place V7CURS.COM somewhere
on your PATH.
TECH STUFF
V7CURS hooks INT 10H, the video services interrupt, in order to
restore the non-blinking cursor after a mode set. It shouldn't cause
any trouble; there are no hot keys or anything like that. The cursor
is set by reading and writing registers on the V7VGA chip.

attacks of euphoria induced by not having to look at that blinkin'
cursor anymore.
