## Description

### USB Serial Terminal Chrome Extension

USB Serial Terminal is a specialized tool designed for seamless serial communication via USB-OTG on Android devices. It supports a variety of serial devices including CP210X, FTDI, PL2303, CH34X, and CDC/ACM devices, enabling users to debug hardware effectively by sending and receiving serial commands.

Key features include customizable baud rate, data bits, parity checks, and stop bits settings, separate panels for input and output, and options to send and receive data in ASCII or HEX formats. Users can also create custom buttons for frequently sent commands, choose end-of-line characters like \r or \n, and easily copy sent data. Additional conveniences include a send log file functionality, screen on/off toggle, font size adjustment, and an option to remove ads. Note that the Android device must support USB Host mode to use this extension effectively.

Ideal for developers and engineers working with serial devices, this extension offers a streamlined interface to communicate directly through USB-OTG cables on mobile devices.
