16c95x Serial - Port Driver

To understand the driver, you must first understand the hardware. The 16C95X (including models like the 16C950, 16C952, and 16C954) is an advanced UART standard developed to succeed older standards like the 16C550 and 16C750.

The 16C95x can be configured for RS485 half-duplex operation. In this mode, the driver can automatically control the DTR (Data Terminal Ready) pin to enable the transmitter only when data is being sent. This simplifies the creation of robust multi-drop serial networks. 16c95x serial port driver

The 16C95x’s 128-byte FIFOs drastically change the interrupt strategy compared to legacy UARTs.

What is the of your serial card/adapter? To understand the driver, you must first understand

To understand the driver, you must understand the hardware it controls. The 16C95X family (primarily built around the Oxford OX16C950 or StarTech/Exar variants) represents the pinnacle of standard hardware serial ports. It is fully backward compatible with the older 16C550 and 16C450 standards but introduces massive performance upgrades. Key Hardware Capabilities

Traditional UARTs require specific crystal frequencies to generate standard baud rates. The 16C95x adds a fractional divider, allowing precise baud rates with any reference clock. The 16C95x can be configured for RS485 half-duplex operation
