In general once you’re connecting over SSH the connection itself is always in raw mode and then the remote host deals with its pty normally (which can be in line or raw mode). Terminals with special shell integrations usually need them installed on the remote host too (some have support that does that somewhat transparently though).

This is why mosh can have better behaviour than pure SSH over high latency connections. However this feature isn’t going to apply to mosh.

I wonder if SSH can honor line-buffered mode. It should be able to detect it, but then if it incorrectly switches to line buffering then random stuff might deadlock.
