class ReadStream
extends net.Socket
Usage in Deno
```typescript import { ReadStream } from "node:node__tty.d.ts"; ```Represents the readable side of a TTY. In normal circumstances `process.stdin` will be the only `tty.ReadStream` instance in a Node.js
process and there should be no reason to create additional instances.
isRaw: boolean
A `boolean` that is `true` if the TTY is currently configured to operate as a
raw device.
This flag is always `false` when a process starts, even if the terminal is
operating in raw mode. Its value will change with subsequent calls to `setRawMode`.
isTTY: boolean
A `boolean` that is always `true` for `tty.ReadStream` instances.
setRawMode(mode: boolean): this
Allows configuration of `tty.ReadStream` so that it operates as a raw device.
When in raw mode, input is always available character-by-character, not
including modifiers. Additionally, all special processing of characters by the
terminal is disabled, including echoing input
characters. Ctrl+C will no longer cause a `SIGINT` when
in this mode.
