This is from Karen Leuther at Realmed...
It would be helpful in the near future that I.E. updates
the TEREADYWHEN documentation section with good
explainations and examples. We are all really struggling
to understand the new commands. Even after you sent me
this email, it still did not explain all the types or how
to have a timeout and a settletime in the same statement
(which I could not figure out).
