Abstract: The inventive device for controlling a computer mouse-type cursor relates to computer engineering and consists of a unit for reading out an identifier coding data, a mouse controller and control keys connected to the first and second outputs thereof. Said read out unit is provided with a channel for a multicoordinate identifier. The device is provided with a control key for code reading connected to the third output of the mouse controller and to an additional controller which is connected to the read out unit and to the thirst and second controller outputs and comprises a serially connected sequential code-to-signal converter, storage unit, code readout unit and a decoder. The control input of the code readout unit is connected to the third output of the mouse controller and the control output thereof is connected to the control input of the storage unit, all said keys being connected to a power source.

Abstract: In one embodiment of the invention a method includes receiving at a server a packet from an application including information associated with the application in a sender field and a numeric representation of a connect function in a command field. A response packet is created and can be sent to the application. In some embodiments, the server creates a failed authentication notification packet and sends it to the application.
