Ray Duncan's book says that the blink is generated by the hardware.
You can set the scan lines which the cursor occupies by an interrupt,
but not the blink.

I have been told that there is a package that provides a non-blinking
cursor, I think by Nostradamus.  Supposedly what it does is specify
that the system cursor occupy no scan lines, thus making it be
invisible, and then it provides a cursor of its own.  The claim was
that it is slow, because it is managing its own cursor and also that
screen output must write twice as much (the invisible system cursor
and then the software cursor).  I haven't seen it myself so can't say.

If you just want to change the shape of the cursor (or get rid of it),
the code to do so is given in many books.
