## Description

FTDI AOA HyperTerm is a specialized Android application designed to interface with FTDI's FT311D and FT312D USB Host to UART devices. Leveraging Android's Open Accessory Protocol (available from Honeycomb 3.1+), it enables seamless communication between Android devices and UART-based hardware without additional drivers.

Key features include support for UART interfaces with RXD, TXD, RTS, and CTS pins, flow control compatibility, and selectable baud rates ranging from 300 to 921600 bps. It also offers robust file transmission capabilities through XModem, YModem, and ZModem protocols. With the FT312D's enhanced 5512-byte RX buffer, the app ensures smooth UART data streaming. USB Plug and Play with error indicators and power delivery over Y-cable configuration adds convenience and reliability. Suitable for TTL, RS232, RS422, and RS485 transceiver types when paired with compatible FTDI chips. This utility is indispensable for developers and engineers integrating Android devices with serial communication hardware.
