Modem Configuration and Profile
3-294 AT Commands Reference Manual August 5, 2008
Two modes exist:
Idle mode: The G24 has no data to send.
Wakeup mode: The G24 has data to send to the terminal.
After the G24 changes the line edge to Wakeup mode, there will be a delay (the default is 30 ms)
sent by the ats102 command before sending any data to the terminal (using RS232 protocol).

S24, Set Number of Seconds Delay Before G24 Enters Sleep Mode
This command activates/disables the Sleep mode. The terminal sends ATS24=5, and if there are
no radio and UART activities, the G24 enters sleep mode in 5 seconds.
If terminal has some indication of the CTS pin activity, it can see:
If +MSCTS=0 (default), the line changes its state periodically. (For more information refer to
“+MSCTS, Enable/Disable CTS During Wakeup Period” on page 3-296.)
If +MSCTS=1, the line is switched off at the moment of entering Sleep mode and stays off
even if G24 is awakened.
