Great!

If you need to get a quick report and then close, you might want to 
forget about the 'with message' parts and do it all in a function.  
Your app will freeze during this function, though.  You might want to 
consider setting the timeout and then using 'until numToChar(13)' or 
something similar.

If you need other things to keep running, then you might want to use 
'with message'.  In that case, you will want to have a handler to get 
things started (open).  The open callback would do the write.  The 
write callback would do the read until some char (or start a cycle of 
'read until empty' until some time has past or all data received).  The 
read callback would process the response and then do the close.

A compromise would be to do the first but use 'with messages' in the 
wait.  You may need to avoid repeated nested queries.
