VERSION 1.0

OX16C95x (standard UARTs)
4.2.1 Windows 95/98 and Windows 2000 drivers for standard UARTs
Overview
The drivers for standard ports use the same port driver as the OX16PCI954 set, therefore the same features are available:
•
128-byte receiver and transmitter FIFOs
•
Adjustable receiver and transmitter interrupt trigger level
•
Automatic flow control
•
Quad speed (using Times clock register)
•
Flexible baud rate generation up to 60Mbps (50Mbps on OX16C954)
•
RS485 half-duplex configuration
Installation
Windows will identify all COM ports as standard communications ports. Once a 95x COM port is installed as a generic port, update the
driver as follows:
1. Click on Start / Settings / Control Panel
2. Double click “System” to bring up the system properties dialog box
3. Select the “Device Manager” tab of this dialog (with the “View devices by type” option selected.
4. Now click on the [+] next to the “Ports (COM & LPT)” icon to show the list of installed COM ports (If this section is not present or
no COM ports are listed, there are no serial devices installed in Windows. To install COM port hardware, consult your Windows /
Hardware documentation.)
5. Double click on the port you want to install the new driver for to bring up the settings dialog for that port
6. Select the driver tab and click the update/change driver button.
7. Windows 95
Click on “Have Disk” and specify the location of the driver files. Click OK
The files will now be copied and the driver installed.
8. Windows 98
When the “Update Device Driver Wizard” asks what you want Windows to do, select “Search for a better driver” and then click next.
When asked where to select the “Specify Location” box and type the location of the driver files. Click ‘next’ and the driver will be
installed.
9. Windows 2000
The system starts the Upgrade Device Driver Wizard. Click ‘Next’
Check “Search for a suitable driver for my device” and click Next. Point the wizard at the driver files (on floppy disk or fixed disk) and
click Next. You may have to enter a path to the driver files.
The system will find a selection of suitable drivers. Check “Install one of the other drivers” and then ‘Next’.
Install the “Oxford Semiconductor OX16C95x Communications port”
The files are copied. Click finish to exit the Wizard (and possibly restart)
Alternatively, the driver can be installed manually for a new device without running the auto-detect routines.
4.2.2 Windows NT4 note
There is no enhanced mode driver for standard UARTs in Windows NT4.0. This is because the generic driver will detect any ISA ports and
use them itself.
