S38 56K Dial Line Rate (default 1)
There are 2 S-registers which support K56flex connections. S38 sets the maximum
56K downstream speed that the modem attempts to connect. To disable K56flex, set
S38 to 0. The S37 register is used to control the upstream V.34 rate. (ref. V.34 Data/
Fax Document). Use the S109 register to control V.90 connections.
S38 = 0 K56flex disabled - V.34 connection (see S37)
S38 = 1 K56flex autorate - maximum achievable connection

S42 Auto Rate (default 1, range 0-1)
0 = auto rate disabled, 1 = enabled.
Range: 0-1
Default: 1
This command is used for testing and debugging only. V.32bis and V.22bis auto rate
is disabled. Retrain operation is disabled or enabled in data mode, and fallback is
disabled in data mode.
S43 Auto Mode (default 1, range 0-1)
0 = auto mode disabled, 1 = enabled
Range: 0-1
Default: 1
This command is used for testing and debugging only. V.32bis startup auto mode
operation is disabled.
