In the Linux kernel, the 16C95x is supported as a subtype of the generic 8250 serial driver. It is identified by the PORT_16C950 type, which triggers special handling for the chip's advanced features, such as its unique baud-rate generation logic, allowing the serial port to achieve speeds up to uartclk/4 instead of the typical uartclk/16 . Step 3: Force the Driver Installation In the

Instead of one interrupt per byte, the Rx FIFO triggers an interrupt when a programmable threshold is reached (e.g., 112 bytes). The driver can then read up to 128 bytes in one ISR loop.
