Terminal adapter for an existing Erlang I/O device, such as an SSH shell's group leader. The device must support character reads, writes, and the :echo and :binary I/O options. Geometry queries are optional.

terminal = Termite.Terminal.start(
  adapter: Termite.Terminal.IODevice,
  device: Process.group_leader()
)

The adapter disables echo while active and restores the previous I/O options when stopped or when its owner exits. It sends input, :winch, and :hup messages through the standard Termite reader reference. Geometry is checked every 250 ms when the device supports it.

This adapter does not switch a physical terminal into raw mode. Use the default adapter for a local terminal. Stop the adapter with Termite.Terminal.stop/1 after restoring any screen modes enabled by the application.
