Abstract
Abstract A link (10) exchanges data between a master (MC) and slave (SC) computer. Each computer has control lines (26A, 42) and incompatible information lines (26B, 26C, CA1-15, CX1-21). The master computer (MC) includes a master interface (28) connected to the information and control lines (26) of the master computer (MC). The master interface (28) has separate intercommunication lines (LA/B) and intermediate (34) lines. This master interface (28) is able to provide an intermediate signal on its intermediate lines (34) in response to signals provided by the master computer (MC) on its control lines (26A). The link (10) includes a computing subsystem (30) and a slave interface (38). The computing subsystem (30) is connected to the intercommunication (LA/B) and intermediate (34) lines of the master interface (28). The computing subsystem (30) has command lines (36) for providing thereon a command signal in response to the intermediate signal. The slave interface (38) is connected to the intercommunication lines (LA/B) of the master interface (28), to the command lines (36) of the computing subsystem (30) and to the control lines (42) of the slave computer (SC). The slave interface (38) can provide a signal to the control lines (42) of the slave computer (SC) in response to the command signal.
