For vt consolectl is implemented in sys/dev/vt/vt_consolectl.c. It
implements two ioctls: CONS_GETVERS (which returns a constant version
number) and CONS_MOUSECTL (for mouse events, from e.g. moused). What
FreeBSD version are you running? NYC*BUG's dmesgd turns up consolectl
Giant warnings only for 12.x and 13.0.
