Using USB with DOS Applications
Using the USB Serial Adapter With DOS Applications
To enable the USB Serial Adapter to work with DOS applications, follow the instructions in Adding DOS Box Support. 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.
