I'm trying to have a node.js eval piped to a ssh2 stream. And I'm having some interesting issues. Mainly how either ssh2 or ssh clients interpret the data. Let's take a look.

when you run the node process, you get this nice prompt node prompt

so this is how my code looks calling repl

where sshStream is a ssh2 stream, now because I'm piping the stream, this is how it looks on the other side:

tty

basically the cursor is moving down below, and not staying where it used to, if I type s, then it doesn't get fixed, and the terminal gets even more messed up, does anyone know the causes? How should I fix this?

fixNewLines is basically a pipe that replaces ('\n' into '\r\n' because apparently, that's important for the ssh protocol, otherwise you don't get the desired behaviour)

The reason this happens is because processes behave differently if they're on a PTY than if they're called directly, because there is no PTY, you see that behaviour, you would have to create your own Pseudo-PTY in order to correctly receive and interpret the characters as if you were on a real shell.
