@Andrew It uses ITE8786E. Where could we find drivers for this?

@olivierlambert We are trying to migrate from VMWare to XCP so we want to enable those two on-board serial ports, the goal here is to be
able to communicate with them.

Hey all. We are trying to enable two serial ports on a machine we are trying to migrate to XCP. The machine in question is a MOXA DA820 that has two on-board RS-232/RS-422 ports. We have not been successful on utilizing these ports to send or receive data. We are able, however, to utilize serial ports when passed through PCIE, USB or Ethernet.
We have been reading that XCP is simply not able to utilize physical serial ports and that the only alterntives are the ones we already tried. Is this true? We would like to know more.
