## Description

ZTerminal is a versatile USB terminal software designed for industrial device control. It supports USB to Serial converters based on FTDI and Prolific chips, allowing users to send and receive serial commands such as AT commands to devices like modems and PLCs without additional PC hardware. Users can log communication data, send commands manually or automatically, and choose between ASCII or HEX formats.

The extension also offers handy shortcuts for common hexadecimal control characters and supports script file usage. This enables automating command sequences for field applications directly from an Android device, streamlining industrial device management and communication workflows.
