Serial Input Support

The Serial Input Support component, in conjunction with a communications-aid interface device, allows the user to control the computer using an alternative input device. Such a device needs only to send coded command strings through the computer’s serial port to specify keystrokes and mouse events, which are then treated as if they were standard keyboard or mouse input.
