Barry, Thanks for the info. A couple of follow ups, if I may.
2) This is what I figured. I will probably define a PS global and store the button which was clicked, and kick-off a scheduleAfter timer to clear it after, say, 300ms. If it hasn't been cleared, and is the same button, then I know. Thanks for the tip.

4) So you would recommend setting up a timer to detect no response as expected? if I don't get a response after, say, 2 seconds, I can assume the connection is dead, close the port, and reopen. Right?

5) Thanks for this information. I will setup a timer and track the real-time clock. Can you explain a little more about the 57 seconds thing? You're saying the pronto partially wakes once per minute? Are network connections held open during this time? (This may be a good time to gracefully close the IP connection.) And, by go back to sleep when you do nothing, you mean the user clicks nothing, right?

Thanks for all the info. If anyone has additional suggestions on these or the other two questions, that would be much appreciated.

- Mike
