0.81.1 of the i4b code - namely support of the I4B_VR_REQ ioctl via the i4brbchX device. Ppp controls the phone number, but idle timers and SYNC/RAW decisions are still made by isdnd (in isdnd.rc). This involves a new datalink state machine phase. The ``wait for carrier'' phase happens after dialing but before logging in. The whole dial state should really be abstracted so that each device type can deal with it in its own way (thinking about PPPoE) - but that'll have to wait. The ``set cd'' symantics remain the same for tty devices, but we now delay until we either get CD or timeout waiting (at which time we drop the link if we require CD). For i4b devices we always insist on carrier. Thanks to hm@ for his help, and especially for pointing out that I *don't* need to re-implement isdnd (that was a huge waste of time !) :-]
