Associated article: The Enhanced Parallel Printer Port for Fast I/O
Published source code accompanying the article by Dhananjay V. Gadre and Larry A. Stein in which they discussed the Enhanced Parallel Printer Port protocol, which was developed to provide a high-performance parallel-port link compatible with existing parallel-port peripherals and interfaces. Our authors examine this specification, and present routines for implementing high-speed digital I/O using EPP BIOS calls.
