4 *
5 * Digiboard driver.
6 *
7 * Stage 1. "Better than nothing".
8 *
9 * Based on sio driver by Bruce Evans and on Linux driver by Troy
10 * De Jongh <troyd@digibd.com> or <troyd@skypoint.com>
11 * which is under GNU General Public License version 2 so this driver
12 * is forced to be under GPL 2 too.
13 *
14 * Written by Serge Babkin,
15 * Joint Stock Commercial Bank "Chelindbank"
16 * (Chelyabinsk, Russia)
