A computer system comprises a host computer coupled to a wireless module via a digital interface. The wireless module permits the computer system to communicate with a wireless network. The host computer repeatedly polls the wireless module to determine whether it has received any incoming data from the wireless network, but preferably does not poll the wireless module all of the time. Periodic cessation of polling advantageously helps to extend battery life in the case of a host computer that operates off battery power. This concept, however, can be applied and is useful in the context of desktop electronic systems that operate from AC power.
