V32R ... V.32 / V.32bis available rates
V32R determines the rate signal (specified in ITU V.32bis) that is used in the start-up, retrain
and renegotiate procedures. The coding is the same as in the above mentioned
recommendation, however some of the most commonly used codings are given below.

The selection of the modulation scheme is contained from the 2nd to the 6th parameter.
If automode is selected, any modulation which is masked (set to "0") in one of the parameters, is not
tested/used in automode operation.
For non automode the permitted modulation parameters are used to select the data modulation. If
more than one modulation is permitted, the highest data rate is selected.
