I think I need to clarify my procedure when I run the code from inside a PRG. I insert SET STEP ON right before the ot.output = lqout. When the program stops at that line, I expand the ot object in the watch window. I then step into the next line (ot.output = lqout). I can see something flash in Input in the watch window and then immediately disappear before moving to the next line.

I thought stepping through one line at at time would be the same as typing into the command window as far as timing and waiting for a response goes.
