COMPUTER INTERFACE WITH BOTH WIRED AND WIRELESS LINKS

摘要

Computer and peripheral interfaces that have both wired communication and wireless communication interfaces are provided (see figure 1). In one implementation, one of the two communication interfaces may be activated while the other interface is inactive and is used as a backup. When the operating interface fails, control logic detects the failure and activates the backup interface to maintain the communication. In other implementations, the user can select which of the two types of communication interface is desired.
