S33 10
Sleep Mode Timer: S33 determines when the modem enters sleep or power-down
mode. When enabled (S33
≠ 0), the controller enters sleep mode whenever the mo-
dem has been inactive for a user-programmable time delay (S33). The modem is
considered to be in an inactive state when:
1) No internal processing is being performed;
2) No activity occurs between the host and the modem within a
specified time period;
3) The modem is off-line.
The modem exits sleep mode whenever the host reads or writes to the
modem or when a ring signal is detected.
Sleep mode is disabled by setting S33 to “0”.
Range: 0–90 seconds
S37 0
Maximum Line Speed Attempted: This S-register selects the maximum line speed
allowable (that is, the modem attempts to connect at this speed or falls back to a low-
er speed). Settings for Bn, +MS=m, Nn, and S37 determine the allowable modem
connections. S37 provides the same information as the +MS=m <max rate> param-
eter. Changing the +MS=m <max rate> parameter automatically changes the value
of S37. For example, setting +MS=m <max rate> to 0 sets S37 to 0. Note that S37
has no effect during V.32 bis retraining/rate negotiation.
