Re-attach screen when using input/output stream

[eirikb]

When using input and output on Screen is it possible to attach another stream later?

I'm using ssh2, and want to re-attach to existing Screen when a user re-connect with same public key.

My connection code currently looks like this:

session.on("shell", (accept) => {
  const stream = accept();

  const screen = blessed.screen({
    input: stream,
    output: stream,
  });
  ...

});

I've tried replacing the input, but it seems it must be set like above, can't be changed.
Then I tried attaching a top level Box, but it fails when being added to another Screen.
Then I tried creating a re-attachable Duplex stream, but it closed when the ssh session closed.
