Okay, but I don't see how to use that to solve my particular problem.
I'm not waiting passively to receive a complete string, I have to
react to whatever's sent back, character by character, either by
reporting completion, an error or sending more data. In effect, I
guess, each character is a "complete message" anyway. I don't think
the t.i.protocols offer much for that.
