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! bob prohaska
