TiniLet

This is a good solution in order to read the data by a serial port from some devices such as balances, barcode scanners or some measure tools.
TiniLet is a Java program, which runs on some industrial machines, which are fanless and have no hard disks, so they can work well in hard environments too.

Plugin

At boot time, the firmware in those devices downloads some plugins from a server and these plugins are the application logic, which is about the communication by the serial ports with the connected devices. The configuration is centralized in the server.
