prompt = the prompt to give the user. For example, `"Your name: "`. prompt = the prompt to give the user. For example, `"Your name: "`.
echoChar = the character to show back to the user as they type. The default value of `dchar.init` shows the user their own input back normally. Passing `0` here will disable echo entirely, like a Unix password prompt.
