Can anyone tell me ? You need HDLC before anything else, the D channel runs on HDLC and LAPB. You should probably not bother with emulating the HSCX at all, rather try to provide the functions at the right level of the stack in isdn4bsd. You should be able to find some LAPB code if you look in the 'sys/netccitt' directory of a 2.2.X release (probably have to go back to 2.2.2 or so) or you can resurrect it from the dead using a CVS tree. -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
