[. . . ] If the wrong drivers have been installed or if you are not sure, follow the instructions in section 3. 3, Uninstalling the USB Serial Adapter Drivers, and reinstall the software. If you have enabled DOS Box support, make sure that no other applications are using the Windows® name for the COM port or the DOS name for the COM port (see section 4. 4 Using the USB Serial Adapter with DOS Applications). Communications Garbled If you are using the USB Serial Adapter to communicate between two computers over a serial cable, make sure that the communications settings are the same on each computer. [. . . ] You may need to do this if the USB Serial Adapter has been installed as COM5 or higher, since many DOS applications will only use COM1-COM4. For instance, if you are adding DOS Box support to COM7, you can choose to have DOS applications use the device as COM2 instead, if COM2 is not already in use. COM7 would still be available for use with Windows® applications, but both COM2 and COM7 refer to the same physical device. Therefore, while a DOS application is using COM2, COM7 will be unavailable to Windows® applications and vice-versa. 7 4. Open the "Control Panel" and double-click on "Add/Remove Programs". On the Install/Uninstall page, click on "USB Serial Adapter" software from the list box and click "Add/Remove". You can choose to uninstall the USB Serial Adapter driver and installation files, the mouse driver and installation files, or both. Choose whatever you would like to remove (a check mark will appear in the box next to each item to be uninstalled) and click "OK". Serial Plug-and-Play Device Detection A Plug-and-Play device, such as a modem, can be detected in one of two ways: 1. Unplug the cable and plug the USB B connector to the USB Serial Adapter. Click the "Device Manager" tab on the System Properties page. Click "Refresh". Your Plug-and-Play device should be detected and you may be asked for a device driver if it has not been previously installed. Follow the instructions that came with your serial device to complete the installation. 6 3. Insert the CD labeled "USB Serial Adapter Installation" into your CD drive (typically drive D:\). [. . . ] Click on the "Device Manager" tab on the "System Properties" page. One of the ports will be labeled "USB Comm Port (COM name)" where "COM name" is the name of the new COM port. Adding DOS Box Support (Optional) DOS Box support for the USB Serial Adapter is useful if you intend to use DOS applications, but not necessary for Windows® applications. [. . . ]
