8 Bit Data Transfer By Parallel Port Connection

Abstract

This paper presents a design and performing a special protocol. Using outlet parallel port from EPP’s kind does not used before [1,2] for the operation of data transmission between two computers using 8 bits data transmission.A program was designed using especial protocol for data transmission from and to the computer without dependence on any of the used protocols in the world [1,2,3]with the least possible error. This program was designed using Qbasic language.This program consist of several functions such as window function to indicate whether the computer in reception or transmission or exit case, transmission function, reception function and a function to open the file to be send, bits check function on parallel port. This enables us to determine the transmission and reception time and its status. This program work after providing data cable, which is, depends according to established program
