From cb3824bade2549d7ad059d5802da43312540fdee Mon Sep 17 00:00:00 2001 From: Karsten Keil Date: Wed, 8 Jul 2009 14:21:12 +0200 Subject: ISDN: Make isdnhdlc usable for other ISDN drivers isdnhdlc is useful for other ISDN drivers as well. Move the include file to a central location and the source to the central isdn location.
