Events done on the serial console does not get recorded via the auditd

the events done on the serial console does not get logged. I am using BSM audit.

I have enabled all audit flags. Is there anything that im missing?

Please help!!

Please provide details on what you mean.

A serial console is a "Craft terminal for telecommunications equipment" as mentioned in this link : Why use a serial console?

Here I log into the console so the terminal will be "/dev/console" .
Now, any kind of activity on this terminal does not get recorded by the audit log.
