S28-S29 Reserved (none)
S30 Sleep Mode Timer: (10)
S30 determines when the modem enters Sleep or Powerdown Mode.
When enabled (S30 <> 0), the DSuP will enter Sleep Mode whenever the
modem has been inactive for a user-programmable time delay (S30). The
modem is considered to be in an inactive state when:
1) No internal processing is being performed;
2) There is no activity 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 rems or writes to the
modem, or a ring signal is detected. Sleep Mode is disabled by setting
S30 to zero.
Range: 0-90 seconds
S37 Maximum Line Speed Attempted: (0)
This S-register selects the maximum line speed allowable (i.e., the
modem will attempt to connect at this speed or fallback to a lower speed).
Note that S37 has no effect during V.32bis retraining/rate negotiation.
