Great emphasis was placed on documentation and process tracking.

The difference between the new GUI and classic applications is in its behavior, it's not possible to accidentally touch the device to increase its performance. User interface with all its elements was designed to fulfill all the needs of the user. The application was tested on Linux and Windows platforms.

The main task of the project was to test French library ALIZE by building an application for voice identification. The project objectives were met, 16 speakers tested the application which demonstrated 100% reliability (Fig. 3 - upper left corner). The application was tested on three platforms.

The application was used to diagnose and debug protocols that use the serial port. It displayed incoming messages and allowed messages to be sent to the chat window. All port parameters were configurable with the ability to view multiple ports at the same time.
