The 'data shunt box' an easy, inexpensive way to transfer text files between computers

摘要

A simple, low-cost mechanical switch is used in transfering text files between computers of widely varying size, architecture, manufacturer, and geographic location utilizing standard serial interfaces, typically at 300-1200 baud. No special software is required since the standard utility programs of each computer are used to transmit and receive the text. The only requirement is that the effective rate of character transmission must be slow enough to allow the receiving system to process a character before the next one arrives since no hand-shaking interlock is provided. With the data shunt box, direct 'media-free' data transfer between different systems is within the budget of any user of small systems.
