16c95x Serial Port Driver -

The driver must manage bank switching carefully, restoring LCR after accessing extended registers.

For many modern Linux distributions (Ubuntu, Debian, CentOS), inserting a PCIe card with a 16C95x chip will cause the kernel to automatically identify the hardware and bind it to the 8250_pci driver. Checking if the Card is Recognized

One of the 16C95x’s most powerful features is automatic RTS/CTS handshaking. When enabled via the EFR register, the UART internally controls RTS based on Rx FIFO fill level and monitors CTS to pause transmission.

Despite its robust design, interfacing legacy serial hardware with modern operating systems can throw up a few roadblocks. Here is how to fix the most common issues: Error: Code 10 (This device cannot start)

Because the 16C95x is an interface chip rather than a standalone peripheral, installing its driver requires updating the hardware's device path. Follow these concrete steps to get your expansion card running flawlessly: Step 1: Obtain the Correct Driver 16c95x serial port driver
