Motorola AT Commands G24-L - S24, Set Number of Seconds Delay before G24-L Enters Sleep Mode; G24-L Lines When S24 > 0

Modem Configuration and Profile
3-202 G24-L AT Commands Reference Manual April 15, 2008
Two modes exist:
• Idle mode: The G24-L has no data to send.
• Wakeup mode: The G24-L has data to send to the terminal.
After the G24-L 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-L 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-L 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 3-205.)
• If +MSCTS=1, the line is switched off at the moment of entering Sleep mode and stays off
even if G24-L is awakened.
