Maybe this will help. The path is

workstation> Ethernet > terminal server:usb-serial > serial wires> GPIO 8/10

I hesitated to use the words "terminal server" because that has implications
(distinct IP address, multiple serial interfaces) that don't exist here. 

The workstation is a RasPiOS Pi4, the Pi3 host called pelorus is the terminal
server and the GPIO pins are on the Pi3 host named www.zefox.net .

The Ethernet connection works well enough for all the other hosts  that I think 
we can disregard whether it's wired or WiFi and LAN or WAN or all four. 

Thanks for all your help!
