The method of claim 3, further comprising, in response to the indication action, receiving a selection confirmation input, wherein in response to the selection confirmation input being positive causing the selected modular unit to perform the process, and wherein in response to the selection confirmation input being negative receiving a new selection input for selecting one of the displayed modular units to perform the process. 5. The method of claim 1, wherein each of the wireless communications ports is operable to communicate using at least one of an infra-red transmission protocol and a radio frequency transmission protocol. 6. The method of claim 1, further comprising transmitting an acknowledgement message to the wireless communication port of each of the modular units from which an existence response message was received. 7. The method of claim 6, further comprising the wireless communication port of each of the modular units repeatedly transmitting an existence response message at a randomly determined interval until receipt of an acknowledgement message. 8. The method of claim 7, further comprising randomly determining the randomly determined interval following each transmission of the existence response message. 9. The method of claim 6, further comprising applying a predetermined increase to the response interval following each transmission of the existence response message. 10. The method of claim 9, wherein the predetermined increase comprises at least one of a multiplication factor and an increment. 11. The method of claim 9, wherein the predetermined increase is determined randomly following each transmission of the existence response message. 12. A service device for a computer system including a plurality of modular units, wherein at least one of the plurality of modular units is a computer system carrier having removably received therein at least one removably mountable information processing cartridge, the service device comprising: a wireless communications port operable to transmit an existence request message to a wireless communications port of each of the plurality of modular units and to receive an existence response message including an identifier for the modular unit from at least one of said plurality of modular units; and a display operable to display a list of the modular units from which an existence response message was received; wherein the service device is operable to receive a selection input for selecting at least one of the displayed modular units to perform a process. 13. The service device of claim 12, in response to receiving one or more existence response messages the wireless communications port of the remote service device is operable to transmit an acknowledgement message to each of the modular units from which an existence response message was received. 14.
