Is it possible to read the KVM state over the serial console?

KVM Model:

HDMI 2.1 KVM w/EDID & Serial Control - Single Monitor - Four Computer

USB Interface (5-gigabit or 10-gigbit):

10-gigabit


Problem:

I would like to be able to retrieve the state of the KVM over the serial console.

Are there any other serial console commands than those listed in the manual?
