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).
Installation
Install the hardware by following system instructions. Power up the system. Then follow the instructions below depending on which
functions are required. To upgrade the NT4 driver, simply install over the existing version.

2. When the install application starts, click Next to continue
3. Ensure ‘install’ is selected, then click Next.
4. Click OK to accept the licence agreement.
5. The system will install the driver and start it. The ports are immediately ready for use
Parallel driver
1. Run “Install_Parallel.exe” from the \NT4_Parallel subdirectory on the disk.
2. When the install application starts, click Next to continue
3. Ensure ‘install’ is selected, then click Next.
