Has anybody tried asking for the "echo" from user space?

That is:
  grab time
  raise modem signal
  grab time
  read timestamp over serial port

If you precede that with
  grab time
  lower modem signal
I think that will warm up most of the cache.  Another interesting experiment 
would be to see how much of a difference that makes.

These are my opinions.  I hate spam.
