Yes, the latter.

In that case, I've misunderstood to think you want to run a local
shell. (You mentioned Bash that comes with Git, which led me to that
conclusion.)

AFAIU, plink doesn't assume it will run in full-screen mode, it's
basically a batch-mode ssh client. So indeed it doesn't care about
the devices it is connected to.

See above. PuTTY does this, but I won't expect that from plink.

Right.
