1 /*
3 plipconfig.c: plip-ifconfig program for the Linux PLIP device driver
4 Copyright (c) 1994 John Paul Morrison (VE7JPM).
6 version 0.2
8 Changed by Alan Cox, to reflect the way SIOCDEVPRIVATE is meant to work
9 and for the extra parameter added by Niibe.
11 plipconfig is a quick hack to set PLIP parameters by using driver
12 ioctls. plipconfig will no doubt be revised many times as the Linux
13 PLIP driver and Linux 1.1 mutates.
