S109 K56flex and V.90 Selection (default 1)
Use this register to disable 56K connections or to choose between K56flex and V.90
protocols. The default setting (S109=1) will attempt K56flex and then V.34 depend-
ing upon the central site modem being called and your phone line conditions.
S109 = 0 Disable all 56K connections
S109 = 1 K56flex only, V.90 disabled (default)
S109 = 2 V.90 only. K56flex disabled
Examples
at&fs38=0s109=0This will disable ALL 56K connections
at&fs38=1s109=1s37=14 This will disable V.90 connections. The modem will
try to connect at K56flex rates with the V.34 up-
stream rate limited to 21.6K bps.
at&fs38=1s109=2This will cause the modem to attempt a V.90 connection only.
If V.90 is not achieved, it will fall back to V.34 rates.
at&fs38=10s109=2 This will cause the modem to attempt a V.90 con-
nection at 40K bps. It will fall back to slower speeds
if it cannot achieve or maintain this rate.
As a suggested “init string” in your communications program, use:
