[. . . ] Check to make sure no other applications are using the COM port. 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. For instance, if one computer is set up for 9600baud, 8 data bits, no parity, one stop bit and hardware handshaking, errors can occur if the settings on the other device do not match. [. . . ] You can choose a different name for DOS than what is used for Windows®. 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. Uninstalling the USB Serial Adapter Drivers 1. Unplug all USB Serial Adapter devices from the USB ports. 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". Right-click the "My Computer" icon on your desktop. Click "Properties" from the menu that appears. Click on the "Device Manager" tab on the "System Properties' page. Click on the "+" next to "Ports (COM & LPT)". One of the ports will be labeled "USB Comm Port (COM name)" where "COM name" is the name of the new COM port. This name will be used in applications. 3 3. 2. Insert the CD labeled "USB Serial Adapter Installation" into your CD drive (typically drive D:\). Insert the flat (type A) connector into an available USB port on your PC or USB hub attached to your PC. Insert the square connector (type B) into the USB Serial Adapter device. You will see "Add New Hardware Wizard". When asked "What do you want Windows® to do?", choose "Search" for the best driver for your device (Recommended).
