AT Commands Reference S-Registers (continued)

S89 Timer to Control Sleep Mode
This command displays the number of seconds of inactivity (no characters sent from the DTE, no RING) in the
off-line command state before the modem places itself into standby mode. A value of zero prevents standby
mode.
Note: If a number between 1 and 4 is entered for this register, it will set the value to 5, and the inactivity before
standby will be 5 seconds. This is done for compatibility with previous products which allowed time-outs
down to 1 s.
