Abstract
Abstract An improved method for cabling of data communications between data terminals and data sets in which the present invention is a cable designed to replace conventional cables that are individualized (or customized) as male/female and/or null modem cable configurations. The present invention consists of a plurality of individual wires wherein each wire is assigned an individual use and meaning whereby a minimum of two wires are assigned to each lead wire from a data terminal which does not have a corresponding lead wire on the receiving data set. The second wire is electrically connected to the first wire allowing continuity in a null modem configuration while allowing a direct connection in a straight cable configuration. With the instant invention, the use of an appropriate second wire is all that is required to create all possible combinations of male-female, straight-null cables.
