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: at&fw2s109=2s38=1s37=14
