Data transfer network for variable protocol management |
December 23, 1986 |
| A 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 |

Line support processor for data transfer system |
January 15, 1985 |
| Data transfers between remote data sets, data terminals and a main host computer are controlled by a peripheral-controller designated as a Line Support Processor (LSP). The LSP manages a plurality of line adapters, each of which handles a separate data comm line. The LSP includes interna |
