V.34
     
         An {ITU-T} {standard} {modem} serial line
        {protocol} using {symbol rate}s of 2400, 2743, 2800, 3000,
        >3200 and 3429 and up to 28800 bits per second.
     
        The official V.34 draft recommendation was titled:
     
           Modem operating at data signalling rates of up to 28 800
           bit/s for use on the general switched telephone network and
           on leased point-to-point 2-wire telephone-type circuits.
     
        During the lengthy process of approval by {ITU-T}, many
        manufacturers released 28.8 kbps modems described as "V.FAST".
        The V.34 recommendation was ratified by {ITU-T} on 20
        September 1994.  {Rockwell} and {US Robotics} both have seats
        on the ITU-T, and have both released {chip set}/{BIOS}
        combinations that they feel will meet V.34.  V.34 modems will
        also support {V.FC} if the manufacturer currently supports
        V.FC (e.g. {Rockwell}).  Some (all?) V.34 modems will also
        support {line probing}.
