Installation:
For the easiest installation, extract the files to a floppy or a CD.  

Insert the floppy/CD that contains the extracted files, and plug the
adapter into the USB port. The New Hardware Wizard will start. If prompted,
make sure to tell the wizard to search on the floppy disk/CD. 

Note:
To verify the adapter installed property, check Device Manager under Ports. 
You should see a device listed as "Prolific USB-to-Serial (COMx)", where x 
is the COM port number that Windows assigns to the adapter. This number is
important, as this is the COM port that you will use in your serial application.
You must make sure that you select this COM port to communicate properly with
your serial device.

Troubleshooting:
Many serial devices and applications cannot work on a COM port higher than 4.
If the COM port is higher than 4, you should change it to a lower number. You
can do that through the Device properties.

To change this COM number assigned, go to Device manager under ports and find
the device, as above. Right-click the device and select Properties. Click the
Port Settings tab. Click the Advanced Button. You will see a box in the lower
left corner to assign a different COM port to the adapter. Please note this
procedure only works for Win ME, 2000, and XP users. 

If you cannot get the serial device to communicate, make sure the settings on
the Properties tab match the ones required for your serial device. Also, under
Advanced Settings (Advanced button, above) try backing down the sliders or 
disable the FIFO buffers (uncheck the box) altogether. 

Finally, if you still are having communication issues, contact your serial 
device manufacturer. If our adapter shows correctly in Device Manager (per above),
it is installed correctly and there is nothing further we can do. The problem
is with your serial device or its software settings.

Uninstall:

To remove the drivers, run the DRemover98_2k.exe file and reboot.
