Attorney, Agent or FirmInternational ClassG06F 13/38 (20060101)AbstractA data transfer network uses an I/O subsystem to support a main host computer in managing data transfers to and from remote data terminals. The I/O subsystem may constitute one or more units called a Line Support Processor. The Line Support Processor uses internal processor means to control a plurality of line adapters each of which has a data-comm line to a data set or data terminal. Control operations by said internal processor permit selected line adapters to operate selected types of protocols using synchronous or asynchronous transmission. Data communication information and commands in high level language data are loaded into auxiliary memories in the internal processor means and into each line adapter where the internal processor means acts to convert this language data into usable protocols. | |
