AFAIK dormancy applies to modems that supports data bearers.  At least
in EVDO, the terminal is in dormant state when resources exist for the
bearer (eg addresses, network side tunnels, etc), but the traffic
channel is not actually in-use because no data is being sent or
received.  QMI has a WDS event indication for dormancy, Huawei modems
have indications for it, and I've seen other command sets that have this
indication as well.
