Abstract
The multitude of computer input-output devices currently
marketed, and their decreasing cost, often raises problems of transfer of
information between different media. These are aggravated by the ready
availability of low-cost processing power in the form of mini- and
micro-computers, which encourage the development of many separate
computer configurations, each with their own input-output facilities.
Processor-processor links using existing input-output channels
constitute a cheap and simple way of overcoming these incompatibilities.
This paper discusses the software and hardware technology for handling
such links, placing emphasis on simple, easily-implementable protocols
and hardware rather than on maximum bandwidth utilization and
automatic error correction.
