S109 (default: 1) | K56flex and V.90 Selection |
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=0 | This 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 upstream rate limited to 21.6K bps.
at&fs38=1s109=2 This 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 connection 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
