Chapter 3: AT Commands Reference
In order to limit the number of interrupts on the DTE side and reduce data sending delay time on
our side, H24 sends wakeup-out pulse when the interval between one burst of sent/received data
to the other is bigger than specified in ATS100.
Command Type Syntax Response/Action Remarks
Set ATS100= OK
or:
+CME ERROR:
Read ATS100?
OK
The set command sets the terminal
minimum time limit for entering
sleep mode.
The Read command returns the
current ATS100 value.
The following table shows the S100 parameters.
Table 3-174: S100 parameters
Description Remarks
Time interval between one burst of sent/received data
to the other before the terminal enters sleep mode.
0: Wakeup out feature isn't active. (default when +S100
set command is never used)
1 - 255: Time in seconds.
This value is saved on
power down.
Example

+MSCTS, Enable/Disable CTS During Wakeup Period
This command defines the behavior of the CTS line when the H24 is in normal mode (not Sleep
mode).
The command configures the H24 CTS line behavior always to follow the flow control
requirements, or to follow it only if the terminal initiated a serial transmission session. This saves
the terminal from following the CTS interrupt every time the H24 exits Sleep mode for internal
H24 reasons (non-terminal communication related reasons).
