Custom solutions & drivers for the OX16PCI954
VERSION 1.0
4.1.2 Windows NT4 driver for OX16PCI954
Overview
The Windows NT4 driver creates a Device Object for each port, and registers this with the operating system. The serial port driver enables
the following 16C95x features:
·
·
·
·
128-byte receiver and transmitter FIFOs
Optimized receiver interrupt handling – uses readable fill levels and thresholds
Automatic clock speed detection
Memory-mapped operation for efficient throughput
A separate parallel port driver is provided, which creates the device Object and registers it with the Printer class driver.
The Windows NT4 driver searches the PCI bus for the VendorID / DeviceID combinations specified in the oxser.inf file. If the chip has been
reconfigured with the EEPROM (e.g. DeviceID reconfigured as 0x950A to be a two-serial port solution) the oxser.inf file will need to be
modified (see application note “Custom Drivers” for more information).
