: These chips feature much larger 128-byte FIFOs (First-In, First-Out buffers) compared to the tiny 16-byte buffers in traditional 16550 UARTs, which significantly reduces the risk of data loss during high-speed transfers.
If you are setting up this hardware, let me know you are using and the specific error message or behavior you are seeing so I can provide the exact steps to fix it. Share public link
This guide explains how to install, configure, and troubleshoot the 16C95x serial port driver. Understanding the 16C95x High-Performance UART 16c95x serial port driver
// Define the serial port's I/O address #define SERIAL_PORT 0x3F8
The driver then simply writes to THR; the hardware handles the turnaround delay. : These chips feature much larger 128-byte FIFOs
Many 16C95x chips support automatic direction control for RS-485 communication, which the driver must toggle.
