Full Description

Scope

The packet protocol described by this standard allows a device to carry on multiple, concurrent exchanges of data and/or control information with another device across a single point-to-point link. the protocol is not a device control language. The protocol provides basic transportlevel flow control and multiplexing services. The multiplexed information exchanges are independent and blocking of one has no effect on any otherre. The protocol shall operate over IEEE 1284-1994 interfaces and may operate over other point-to-point interfaces.

Purpose

Define and describe an updated PC parallel interface by adding multiple modews of operation which provide for higher speed, bi-directional communication between devices. The IEEE 1284-1994 stgandard does not provide anything beyond a physical protocol. The 1284.4 standard specifies a point-to-point protocol with one or more layers above the physical interface and below the application. These layers take on the functions and characteristics of the transport and session layers of the OSI model.

Abstract

New IEEE Standard - Inactive-Withdrawn. Administratively Withdrawn February 2006 A device to carry on multiple, concurrent exchanges of data and/or control informationwith another device across a single point-to-point link allowed by the packet protocol is describedin this standard. The protocol is not a device control language. The protocol provides basictransport-level flow control and multiplexing services. The multiplexed information exchanges areindependent, and blocking of one has no effect on any otherre. The protocol shall operate over inter-faces such as described in IEEE Std 1284-2000.
