A fault tolerant communication apparatus provides redundant links between at least two computers. The apparatus includes a first set of links connected to a first computer, a second set of links connected to at least one second computer, and a communication controller between the first set of links and the second set of links. The communication controller ensures communication between the two computers if there is at least one active link between the computers for data communication. USB/Firewire based serial links can be used.
