To disable or stop the console beep (also known as the bell) on a FreeBSD system, you can use the kbdcontrol command. This command is used to control the keyboard and console settings on FreeBSD systems.
To disable the console beep, you can use the following command:
kbdcontrol -b off
This will disable the console beep. To re-enable the console beep, you can use the following command:
kbdcontrol -b on
To make the change permanent, you can add the kbdcontrol command to the /etc/rc.local file. For example:
kbdcontrol -b off
This will disable the console beep every time the system is booted.
