This\n * is necessary for compatibility with, for example, the\n * `attach.js` addon.\n *\n * - event `zmodemDetect` - fired on Zmodem.Sentrys `on_detect` callback.\n * Passes the zmodem.js Detection object.\n *\n * - event `zmodemRetract` - fired on Zmodem.Sentrys `on_retract` callback.\n *\n * Youll need to provide logic to handle uploads and downloads.\n * See zmodem.jss documentation for more details.\n *\n * **IMPORTANT:** After you confirm() a zmodem.js Detection, if you have\n * used the `attach` or `terminado` addons, youll need to suspend their\n * operation for the duration of the ZMODEM session.
