Serial Card supportted for EXi 6.7

Hi there,

Wherer can i find a supported PCI-Express Serial Cards with for example 8 or 16 Ports to allow me passthrough to different Guests.

example:      COM1 to Guest 1

                    com2+3 TO Guest 2

and so on.

I searched the VMware Compatibility Matrix but found nothing.

So which PCI Express Serial Cards are supported in ESXi 6.7.

Thanks you!
