Occasionally, the hardware installs correctly, but the OS fails to map a COM port number due to registry exhaustion. 16c95x serial port driver
It supports data transfer speeds up to 15 Mbps (asynchronus), far exceeding the standard 115.2 Kbps limitation of older hardware.
The driver set consists of Plug and Play (PnP) bus drivers that enumerate devices on the PCI or ISA bus and create device objects for each UART and parallel port discovered. Each UART is then managed by a single-port driver that exposes standard COM port interfaces to the OS. static struct uart_ops ops =
: Provides automated hardware (RTS/CTS or DSR/DTR) and software (Xon/Xoff) flow control to prevent buffer overruns. Flexible Configuration Fully adjustable interrupt trigger levels. Support for 9-bit data frames , often used in multi-drop industrial protocols. RS-485 half-duplex configuration support. Backward Compatibility
