HybridDog has taken over maintaining this mod https://github.com/HybridDog/digipad The digipad allows you to enter a number 1-10 digits, which will be sent down a digiline. You can select channels 1-3 with buttons in the formspec. channels are prefixed with "keypad" so Channel 1 transmits on "keypad1" etc. The hardened digipad shares the same functions, but has different physical properties. It is a full 1m wide, so it can cover a wire channel in a wall completely. It also has the same digging properties as a steel block, so some random noob with a stone pickaxe can't steal it. The keyboard allows arbitrary strings to be entered. It sends only on channel "keyb1" right now. The terminal allows entering strings, and receiving responses. It's channel prefix is "tty" and the suffix can be set with /channel <suffix>. Default suffix is "1", making the channel "tty1". "/help" will display a help text. See also - https://github.com/lordcirth/minetest-wireless adds wireless transmitters/receivers - excellent for passworded doors with no traceable wire. Just link a digipad to a wireless transmitter, and a receiver to the luacontroller for the door.
