See at end for logfile. As i said in an earlier mail, this are the same problems arising when using isdntest to call yourself and are caused by the inner layers of i4b not being decoupled by message queues. This will not go away until someone converts the design from synchronous function calls to asynchronous message queues (which is major undertaking). > b) my impression is, that somewhere there is an infinite FIFO. The FIFO is finite. For the ipr tx interface it is 50 mbufs fast queue plus 50 mbufs slow queue plus 50 mbufs send queue plus 50 mbufs hscx tx queue. Which is quite large. > c) I'm a bit confused about how sync ppp handles interfaces up and down and > dialing.

No idea since i still do not use PPP (which will change RSN). > d) the command window for hanging up a line doesn't react to any keystroke > I could identify. Just leaves the cursor after the last line it offers. Curses problem in NetBSD ??? This does not happen in FreeBSD.
