  These are not modem speeds, but port speeds.  You
need your port speed to be higher than modem speed
else your modem will be constantly sending "wait"
signals while it decompresses buffered data.
  If your modem speed and port speed are both set at
56kbps, your throughput will be considerably deoptimized.

  Of course.

  I can't answer about the dialer section since I don't
really have one, but I *believe* the ATZ / ATFx modem 
initialization string sets your modem to its maximum.  
Then during negotiation with the remote modem, the 
highest reliable speed will be determined and used.
  Generally you don't get a 54kbps connection if your 
telephone office is more than about a quarter mile away.
In that case, the modems will negotiate the speed down 
to 48 or even 42 kbps.
