Ernst - terminal server in Node.js

What is this

Ernst is something like getty but for Node.js.

It spends its time in the following loop:

1. Open a serial port
2. Display a welcome banner
3. If the user requests connection, sublaunch some process
4. Forward text from that process to and from the port
5. Clean up and loop back to step 2

Why?

This allows you to set up some kind of terminal, whether physical or virtual, and offer a process over it.

How to use

1. Create a config.json file (as below)
2. npm i
3. node index.js

Config

create config.json

{
    "portPath": "/dev/tty.whatever",
    "saltCmd": "/usr/bin/ssh",
    "saltArgs": [
        "…"
    ],
    "baudRate": 19200
}
