If i recall correctly you can pass through USB ports if needed. Also given that serial/parallel ports are very simple you can often just write a driver or use the super powerful socat to massage things if needed. I once used socat to serve autopilot simulators that spawned on socat's socket accept and piped to actual serials. I could then serve serial over the networks. Really if I was a poet i would write an ode to socat Anyway, peripherals were non the wiser on the nature of the piping. A bit of annoying plumbing but can be done and enables you to have scalable CIs for embedded devices.
