Driver: 16c95x Serial Port

// Transmit data static void transmit_data(char *data, int len) { // Write data to the transmit hold register for (int i = 0; i < len; i++) { outb(io_base + THR, data[i]); } }

// Define the serial port's I/O address #define SERIAL_PORT 0x3F8 16c95x serial port driver

Here's a simple example of a 16C95X serial port driver in C, which demonstrates how to initialize the serial port and transmit data: // Transmit data static void transmit_data(char *data, int

return 0; }

// Set the baud rate to 9600 bps outb(io_base + 0x03, 0x83); // LCR = 0x83 (DLAB = 1) outb(io_base + 0x00, 0x60); // RBR = 0x60 (baud rate = 9600) outb(io_base + 0x01, 0x00); // THR = 0x00 outb(io_base + 0x03, 0x03); // LCR = 0x03 (DLAB = 0) i++) { outb(io_base + THR
