Well this is what I have been thinking about when using asynchronous but could not see the benefit of the single thread issue. I say this because all the emulator instances can interact at different times not just in one and only one. For instance I have a query running on one terminal and it updates the screen while I am on another terminal waiting for the other to finish. I can still work on the other terminals and the interaction is still going on in the others. There are also timing marks that are sent and heartbeat-keepalives that still have to be used between the other terminals as well. I apoligize for my blindnes for all those out there that understand the asynchronous better than I do but do not see how to handle this situation in the channel switching code. Will this work? If it will then it is an option for me to continue with. I would really hate to tear all of that code apart again just to find out it will not work. Like I said have only used the asynchronous in a small server part but my mind will not wrap around putting this to use on the client side. Maybe I am not seeing the forest for the trees in front. Thanks for the feedback Wim.
