Subject: [ANNOUNCE] eppio v 0.1 -- EPP Command Line Utility
The 'eppio' utility provides a command-line interface directly to
enhanced parallel port hardware on a PC running Linux.
Developed to support a research group that needs to transfer data to and
from a FPGA circuit-prototype board, this utility may be useful to other
researchers, engineers, developers, students or hobbyists who want to
drive a peripherial device which communicates using IEEE 1284 EPP
protocol.
The command-line interface allows users to easily prototype and debug
higher-level device communications manually, or with a scripting
language.
Example Usage;
'eppio --write-address=1 --read-data --write-data=02ab --read-data=100'
'eppio -wa: 1 -rd -wd: 02ab -rd: 100'
Both example commands do the same thing. They begin by writing a hex '1'
byte to the EPP address channel. Then they read a byte from the data
channel, and output it in hex to stdout. Then they write a hex '2' byte
to the data channel, followed by a hex 'ab' byte. And lastly, they read
hex 100 bytes from the data channel, with output again in hex to stdout.
System Requirements:
To use 'eppio', you will need a PC compatible machine (Intel x86
architecture) running the Linux operating system. In addition, you must
have a hardware EPP port, either on the motherboard or on an adapter
card.
To compile the source, you will need a recent version of GNU gcc, and
GNU libc version 2+.

Tech Note:
'eppio' uses ioperm() and inb(), outb() to communicate with the parallel
port in user space. It does not use the parport device driver.
