Hi, there is a new I4B driver available at: http://home.c2i.net/hselasky/isdn4bsd/privat/temporary/ that compiles with FreeBSD 5.3-RC1 Hence I have made so many changes to the I4B subsystem, my driver will not get distributed. Is there anyone that agrees, it is time to upgrade the ISDN- subsystem of FreeBSD? -HPS
