AT Commands Affecting ITU-T V.90 Operation
There are 3 S-registers which support K56flex, V.90, and V.34 connections. S38 sets
the maximum downstream speed that the modem attempts to connect. To disable
V.90, set S38 to 0. The S37 register is used to control the upstream V.34 rate. Use the
S109 register to select between K56flex and V.90 protocols.
