16C95x Serial Port

The refers to a high-performance UART (Universal Asynchronous Receiver/Transmitter) typically found on Oxford Semiconductor based PCI or PCIe expansion cards. These ports are common in industrial equipment, modems, and legacy hardware interfaces due to their large 128-byte or 256-byte FIFO buffers. Quick Fix: Installation Guide

• struct uart_driver – top-level registration
• struct uart_port – per-port hardware abstraction
• struct uart_ops – callback functions (tx, rx, start_tx, stop_tx, etc.)
