Not really. We need to have the sio buffering so that there'll be a
continuous stream of data to send (while ppp's doing other things).
I would think that the default max queue size (2248 bytes?) would be
sufficient for good response with a reasonably fast modem - a 33.6k
modem should send 2248 bytes in about .53 of a second.
