Unfortunately two things come together: I do not always have enough
time, and communication with Hellmuth, my mentor, is also a little bit
tough. Currently I am waiting for an answer to my proposal to make the
next, real integration step for c4b.

Regarding these sources my far goal is to let all i4b parts base on CAPI
and the CAPI manager. But this requires to transform the D-channel
sources stack to fit as a driver under the CAPI manager. A CAPI layer
module is already available. But the passive D-channel stack will take
some time, if no one helps. As of other inquiries my current work is to
implement drivers for Eicon DIVA Server ISDN boards, besides integration
of c4b into the source tree.
