let device = new DeviceController();

device.UART.write("LED1.set();\n");

eval​

eval<T>(expr: string, cb:Function): void

This function uses a call back to return a calculated value, similar to write you can run code on the device, this method has the addition of returning a response.

let device = new DeviceController();

device.UART.eval("LED1;\n", (val) => {
  console.log(val);
});
