A number of people have reported this, and looking at it, I think it's a bug in bhyve. nmdm attempts to simulate modem control (not quite correctly - run back-back cu's to see some of the behaviour), but also bhyve doesn't open the device non-blocking. This results in the open() syscall waiting for simulated carrier-detect to arrive, which doesn't happen until the other end of the nmdm is opened. A fix should be showing up shortly. later, Peter.
