Advanced Settings

Serial transmission applications use names such as COM3 and COM4 to identify COM ports. Unfortunately,

most USB-to-serial products are unable to use fixed COM names on the host PC. This means the names of the

COM ports change when the USB-to-serial device is plugged into a different USB port, either on the same or a

different PC, forcing the user to reconfigure the COM names manually from within the application. Moxa’s

UPort™ 1200/1400/1600 USB-to-serial converters have two advanced features that allow them to use fixed

COM names when the user enables the COM port.

With Moxa’s COM Preserver™ function or fixed-base COM mode, the COM names remain on the UPort™ device.

Moreover, the COM Preserver™ function can even create the same COM port names on a different host PC. With

this feature, you do not need to modify application programs, or rebuild the entire project every time you install

a new operating system or upgrade the computer. Don’t worry about moving the UPort™ from one USB hub to

another, or even from one computer to another.

COM Preserver – Driver Setting Management

UPort provides one special function to help you manage the UPort settings. In the general case, you need write

down all the settings including COM number to prevent them from being lost. In some applications, to clone

multiple systems you also need to worry about how to clone the COM Port settings. Using the UPort COM

Preserver function, you just need to save all the settings into UPort device directly– just like a USB Mass

Storage device. You do not need to record it using additional paper or disk. If your host crashes, you can just

install the driver into new host, plug the original UPort and click the Restore button to restore all settings back

very quickly.

NOTE

If you want to use these settings in another PC, be sure the PC has a free COM port available. Otherwise, the

new settings will copy over the settings of a COM port that is already in use.

Save all settings to the UPort.
