Luup connectivity

What are connectivity options in Luup realm?

Can it communicate with other networked devices on LAN - what protocols supported?

you have full ethernet/socket control in Luup. And we’ve written daemons that take /dev/usb and /dev/tts devices and make them a listening port. So you should be able to talk to anything that has a linux driver.
