Description Ed Maste freebsd_committer 2015-11-27 00:16:16 UTC
Documented as:
     -b duration.pitch | belltype
             Set the bell duration in milliseconds and pitch in hertz.  If a
             belltype argument is specified, it may be one of normal which
             sets sound parameters back to normal values, off which disables
             the bell entirely, or visual which sets the bell to visual mode,
             i.e., flashes the screen instead.  If belltype is preceded by the
             word quiet., the bell will not be rung when the ringing process
             is in the background vty.  The visual bell, when chosen, applies
             to all vtys; other bell types can be set individually for each

in vt(4) mode kbdcontrol -b has no effect (and does not produce an error).
