Interfaces/Peripherals
The RS232-CTS and RS232-RTS signals are not used in this configuration. Sierra Wireless
recommends the use of hardware flow control, but if not needed, the AT commands
AT&K0
and
AT&W0
can be used to disable the flow control function on the embedded module.
Note:
A 2-wire serial link implementation is not possible if
AT+KSLEEP=0
.
