Some of these also use mpd. I can not say how many plan to keep using this in the future but it may be that the simplest answer is a completely separate sio driver that just has netgraph hooks. I haven't talked with Ed yet but there may be may ways to solve this problem. One that comes to mind is tha tthe way netgraph hooks to other modules assumes a possible queueing of data, and that decoupling could make it a lot easier to connect tehm that was required for slip and ppp. > > If, contrary to my expectation, that you can show a real market > here, then we should make a better interface than linedisc for > such hooks into serial ports. >Received on Tue May 27 2008 - 06:12:41 UTC
