S24 - Sleep Inactivity Timer
S24 sets the length of time, in seconds, that the modem will operate in normal mode with
no detected telephone line or DTE line activity before entering low-power sleep mode.
The timer is reset upon any DTE line or telephone line activity. If the S24 value is zero,
neither DTE line nor telephone inactivity will cause the modem to enter the sleep mode.
Range:
0-255 seconds
Default:
0
