ML> Another question: on a 28.8k modem, if the connection is made at
ML> less than 28.8k (eg 21600), can the modem pick up and renegotiate
ML> a higher speed from this point onwards if the quality of the line
ML> improves? (Personally I don't think so but you'll never know).
ML> I know that the modem can retrain up and down from the connection
ML> speed (eg 21600 -> 19200 ->21600) but I'm not sure about the above.

DK> The connect speed is the highest speed the modem will
DK> go too. It can move anywhere down from this speed. If you
DK> want a higher speed, you have to hang up and ring again.

RB> Only with a 14400 or below V.32bis modem or a VFC modem.....

RB> V.34 will either retrain or speed shift
RB> to a higher speed as conditions improve.

So will any decent V32bis modem too.
