Abstract
The invention relates to a method of effecting in a computer system transmission of data between a digital user unit and a computer resource, the user unit being adapted to detect positions on a base which is provided with a part of a global position-coding pattern. The invention is characterized in that a request for access to a computer resource is received, using a first protocol stack, by the computer system from the user unit, said request containing a position indication, relating to which part of the global position-coding pattern that has been detected by the user unit. The computer system gains access to a computer resource using a communication mode and a second protocol stack. The communication mode is chosen based on the position indication. Only the second protocol stack comprises TCP/IP functionality, so that only data transmitted between the computer system and the computer resource comprises routing information.
