[FEATURE REQUEST] XH-HK4401 switch support over serial

[azbesthu]

There are cheap 4 port hdmi/usb2 switches available on the market. They are not supporting hotkeys, but have a dedicated port for switching inputs. As far as I understand the control port on them is a serial port disguised as a micro-usb connection.

Are there any scripting features for NanoKVM WebUI for placing UI buttons that trigger commands or scripts or gpio / serial communication?

I found this approach on a more pricier other kvm project, with more details about the hardware and serial commands:
pikvm/pikvm#1306
Using with direct UART connection

Hello, NanoKVM has reserved two sets of serial ports: "/dev/ttyS1" and "/dev/ttyS2", you can achieve this using the script tool on the webpage along with the built-in picocom.
