I can no longer connect using ISDN and ML-PPP. It worked just fine in
RedHat-5.2.
I reverted back to the RedHat-5.2 version of ppp:
ppp-2.3.5-1.i386.rpm, but that didn't help. RedHat-6.0 has
ppp-2.3.7-2.i386.rpm. Obviously, the problem lies in the Linux
kernel: in kernel-2.0.36 ppp-2.3.5-1.i386.rpm worked fine. In
kernel-2.2.5-22, neither ppp version works for ISDN.
I have no problem to connect with my slow regular modem.
My ISDN TA modem is a ZyXEL omni.net plus where I am using the asynch
to synch conversion (atb40) with ML-PPP (at&j3).
As you can see from the logs below, I do get a hw connection. The PPP
negotiations fail, however.
Has anyone experienced this and found a solution?
With Kindest Regards
Bertil
