3) If the device is properly installed, 'Serialio.com USB Serial Port' or 'Prolific USB-to-Serial COM Port' will be displayed.
The software driver is properly installed, but the USB-RS232 adaptor does not work as expected
One of the common reasons that software may not work as expected with a USB-Serial adaptor when the devcie is properly installed, is many older programs (and even some new ones) only support a limited number of COM ports (e.g. only COM1 - COM4)
If the USB-RS232 adapter is installed as COM5, it may need to be reassigned to COM1 - COM4 to work with some software.
The following outlines how to to reassign the COM port on Windows XP/2K/Me/98SE
Windows XP
1) Follow steps 1-3 of 'Check the software driver installation'above.
2) Right-click on the 'Prolific USB to Serial Port', then click Properties
3) Click on the 'Port Settings' tab. Click the 'Advanced' button.
4) In the 'COM Port Number' drop-down select the desired port number. For example if the software requires COM2, select COM2. Note the COM port must have '(in use)' listed next to it, if it does then another device with that name is already installed in the system. After selecting the desire port number, click 'OK.'
5) Click 'OK' again, and the device will show up as being on the same COM port that it was before (i.e., COM5), but should show up on the selected port name when the Device Manager dialog is closed and opened again.
6) Close the Device Manager. Launch the software to use with the new COM port.
Windows 2000, Me, and 98 SE (Second Edition)
1) Follow steps 1 2 of 'Check the software driver installation'above.
2) Right-click on the 'Prolific USB to Serial Port', then click Properties.
3) Click on the 'Port Settings' tab. Click the 'Advanced' button.
4) Uncheck 'Use automatic settings'.
5) Select 'Input/Output range'. Click on 'Change Settings'.
6) Type '02E8-02EF' in the Value box. This value will change the port to COM 4. If COM 4 is in use, you must choose another port. The values for each port are.
7) Enter the value, then click OK. Click OK again, then click Yes when the 'Creating a Forced Configuration' window appears. Click OK.
8) Restart the computer. The Device Manager can be checked, to see the COM port change.
Note: Adaptor may not be exactly as pictured above.

The Serial Adapter /Serial Converter - Generally
A serial adapter, also referred to as a serial converter is a small electronic device which can convert one type of data signal into a different type of data signal. The difference between an adapter and a converter generally is that an adapter usually only adapts the physical interface of a device to match a different type of physical interface of a different device whereas a converter converts the actual data stream between two devices. Therefore we will use the term 'converter' in the following.
A serial converter typically converts data between either RS232, RS485, RS422, USB or TCP signals, however some converter designs have other special conversion features. Even the RS232 standard is an older communication protocol it is still used by many modern devices in both business and consumer markets and is also often used for personal and office devices. Actually many new devices designed today are designed with a RS232 serial port, often because RS232 is a very robust and reliable protocol which is fairly easy for program writes to integrate into their system.
Serial converters are used a lot in industrial applications as a way to communicate with factory machinery or to interface with test equipment, however in one particular area the serial converter has also become very useful for consumers who need a serial port in their personal computer. Most new computers today does not have a RS232 COM port which makes the use of a USB to serial converter useful for connecting equipment such as serial printers, scanners, scales and GPS devices, but also many types of business, office and laboratory equipment. A USB to serial converter typically can convert USB to either RS232, RS485 or RS422 signals.
