For a very basic solution, when failover happens, you can have it call
this simple script (in the background most probably):
while true; do
echo -e "^G"
Note that that is a litteral ctrl-g -- you will probably need to use some
keystroke or editor command to get it in there based on whatever editor
you're using. In vi for example, you would type ctrl-v ctrl-g to insert
the litteral ctrl-g.
