Page 40

One special value of S38, S38 = 251, is used for back-to-back (factory) testing of V.34 rates, with DSP code running in external memory. Set S38=251 on both originating and answering modems. (This feature is not valid with ramless solution.)

S42 Auto Rate (default 1, range 0-1)

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. In K56flex mode, S42=0 forces connection at the rate specified by S38 (even if the rate cannot be sustained), without fallback to V.34.

0 = auto rate disabled, 1 = enabled.

Range: 0-1

Default: 1

S43 Auto Mode (default 1, range 0-1)

This command is used for testing and debugging only.

V.32bis startup auto mode operation disabled.

0 = auto mode disabled, 1 = enabled.

Range: 0-1

Default: 1

S48 = 7 Negotiation enabled

S48 = 128 Negotiation disabled; forces immediate fallback options specified in S36
