It seemed a bit unnatural to me to create device nodes instead of keeping a single pointer and I decided it was supposed to do something other then keeping per-open instance. It would be great to have this event/mechanism documented for I'd found it looking through source code in /usr/src/sys. Not the worst place to get information but man pages are better :) -- Sincerely, Oleksandr Tymoshenko PBXpress Communications, Inc. http://www.pbxpress.com Tel./Fax.: +1 866 SIP PBX1 Ext. 656
