There is no "bullet point" in ASCII. ASCII is a text character set
with some control characters. ASCII 7 is a control character intended,
as you have ascertained, to cause an audible tone to be generated.
If you want to output something else, first you should understand that
the bullet glyph is part of the IBM Extended Character Set, not ASCII,
and that the way to display such a thing on your screen may depend on
the exact nature of your system and how you're displaying things on the
screen.
But what I advise is to either use an INT 10H BIOS call (See Ralf
Brown's Interrupt List.) or access video RAM directly.
