A C++ middleware solution designed to modernize industrial hardware integration. This service continuously listens to legacy serial interfaces (RS-232, COM ports, USB-to-Serial adapters) and forwards the captured data—such as barcode scans or weight scale readings—to modern cloud infrastructure (Odoo ERP) via REST API or simulating keyboard input.

• Manufacturing: Connecting 20-year-old heavy-duty digital scales to a modern Odoo Inventory system.
• Retail: Bridging legacy handheld serial barcode scanners to a web-based POS.
• Logistics: Reading data from conveyor belt sensors.

• Low-Level Access: Uses native POSIX termios for direct hardware control without heavy external libraries.
• Configurable Protocol: preset for standard 9600 baud, 8N1 (8 data bits, no parity, 1 stop bit) communication.
• Buffering Engine: Intelligent accumulator handles fragmented data packets to ensure complete messages are processed.

• OS: Linux (Ubuntu / Debian / Embedded Linux)
• Hardware: A Serial device connected via /dev/ttyUSB0 or /dev/ttyS0.

bash g++ -std=c++17 serial_bridge.cpp -o serial_bridge

Edit serial_bridge.cpp to match your specific hardware port: C++

const char* SERIAL_PORT = "/dev/ttyUSB0"; const int BAUD_RATE = B9600; // Options: B9600, B115200, B38400

Connect your device.

Grant permissions (if not running as root):
Bash

sudo usermod -a -G dialout $USER

Run the bridge:
