Functional Description
Many embedded applications use the RS-232 interface to communicate with external systems such as PCs, especially when debugging. But in the PC world, the RS-232 COM port will soon disappear from most new computers, leaving USB as the replacement for serial communication. The simplest way to migrate a device to USB is to emulate RS-232 over the USB bus. The primary advantage of this method is that PC applications use the USB connection as an RS-232 COM connection, making it very simple to debug. This method uses a standard Windows® driver that is included with all versions Microsoft® Windows from Windows 98SE through Windows XP.
