Here in nstar we lock all the modems at 19200 baud and enable hardware
flow control.  Then the modems all handle the stepping down to 2400 and
1200 baud - but the DTE is always set to 19200.  This results in transfer
rates in excess of the carrier (if both ends are using MNP5) - plus
excellent transfer rates at high speed (1700cps on the HST, and 1400cps
on the Trailblazers)..
