@gabe - are you thinking a generic RFC 2217 serial-to-telnet (ser2net) style approach or something more device specific?
I am slightly nervous about suggesting improvements, so in the meantime I’ll continue to use the HW Group’s HW Virtual Serial Port RFC2217 driver. It appears to Windows/Voyager like a COM port but provides a telnet link back to a ser2net server running on the Raspberry Pis connected to the devices.
Works fine for both my Flat Panel (and my Nexdome) - all connected via Ethernet - no more long serial cables hanging off the mount, yay!
