2） Serial port: the serial port uses RJ11 port. The developers can control the peripherals
by sending data from the serial port. The RJ11 of iMin equipment is four-wire and does not support hard-flow control (some peripherals turn on hardware-flow control by default, and these devices can not connect iMin mainframe through RJ11).

Open the cash box
1IminSDKManager.opencashBox();
Scan
For iMin devices, if you use the camera to scan the code, iMin provides a scan code Demo for developers to use, which can identify QR codes and barcodes faster.
