S30 Sleep Mode Timer
S30 determines when the modem enters sleep or powerdown mode.
When enabled (S30 0), the DSµP 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 modem whenever the host reads or writes
to the modem, or a ring signal is detected.
