ComPort for Android USB Serial 2.9

ComPort for Android USB Serial by WINSOFT is a developer component that enables fast, reliable USB-to-serial communication in Android apps built with Delphi or C++Builder (FireMonkey). It abstracts the Android USB Host API and serial protocols, letting you connect to USB-to-serial adapters and embedded devices with minimal code.

Key features:

• High-level API to open/close ports and configure baud rate, data bits, parity, stop bits, and flow control
• Asynchronous read/write with events for data received, device attach/detach, and error handling
• Automatic device discovery and user-permission requests aligned with Android’s USB security model
• Support for multiple concurrent ports and background I/O
• Works with common USB‑to‑serial adapters and devices that expose CDC/ACM or vendor-specific serial interfaces
• Example projects and documentation to help you get started quickly

Typical uses:

• Connecting to microcontrollers and development boards (e.g., Arduino-class devices) via USB serial
• Interfacing with barcode scanners, GPS receivers, PLCs, 3D printers, and other serial instruments
• Building field service, diagnostics, configuration, and data logging tools

Compatibility:

• Designed for Delphi and C++Builder (FMX) targeting Android devices with USB Host/OTG support
• Suitable for modern Android versions and 32/64-bit builds (device and OS must support USB Host)
• Requires a compatible USB cable or OTG adapter

ComPort for Android USB Serial helps you avoid low-level USB work, delivering native performance and a clean API that integrates smoothly into existing FMX projects. For detailed platform/version support and licensing, see the official WINSOFT product page.
