Although few of the Codes of Conduct have already been point out by the author but still few more can be added as under,
1. Be a good listener
2. Meetings ought to be interactive and allow the participants to come up with their suggestions and valuable feedback. A question answer round must be kept at the end in order to clear their doubts.
3. Follow a professional dress code.
4. Keeping notepad and pen ready before meeting starts.
5. Should follow a professional dress code.
Lastly but not the least that minutes of the meeting or MOM needs to be prepared and circulated across all departments for them to take necessary action.
Lectures, seminars, conferences, workshops etc. are also various forms of meetings.
As far as etiquette of meetings is concerned, most of the basic points have already been covered in the responses above. However, punctuality, prior in-depth study of the subject matter and recording of important points in writing are more important aspects of meetings. One should not raise voice while talking or try to belittle others. One should speak only when his/her turn comes and should not unnecessarily poke nose while others are talking. The other participants should be addressed respectfully and politely and at the end of the meeting the proceedings should be recorded in the form of minutes.
Let us encourage each other in sharing knowledge.

Even this challenging situation would ease
Without repeating what others have mentioned, With regards to etiquette, I would personally give more importance to the way the meeting is conducted with regards to the purpose and expected outcome.
There is little point in coming smartly dressed, on time, having the snacks and the cup of coffee and nodding the head, staying neutral most of the times ( I've seen all this happen in high level meetings) but not contributing meaningfully.
For me closed door meeting etiquette would involve
No hidden agenda, No posturing
Information and facts should be shared among all, if it can't be then don't invite the people who cannot be given information.
Have a clear crisp agenda, preferably in the form of specific questions within the time limit.
Have relevant facts and figures in hand so that the members can consider and give their opinions.
Each one's contribution should be valid and not just for the reason to say something.
At the beginning, the chair or the convenor should list out the agenda and importantly the questions for which the people in the room should have a reasonable answer so that the meeting is productive.
Strict hierarchy negates new thoughts and ideas. Age and experience is valuable to in many meetings but mere chronological increase in number in a lethargic mind cannot contribute positively and in the true spirit of the meeting.
Last but not the least, based on the gravity of the issues to be discussed, appropriate time and presence should be mandatory. For instance, the sales and growth plan for the next financial year, this meeting should have the relevant heavy weights and adequate time with the provision of another follow-up meeting.
