Communication during idle-mode and wake up
0
Enabled (AT&K3)
ON
ON or OFF
Data sent by the DTE is correctly received by the module.
Data sent by the module is correctly received by the DTE.
0
Enabled (AT&K3)
OFF
ON or OFF
Data sent by the DTE is correctly received by the module.
Data sent by the module is buffered by the module and will be correctly
received by the DTE when it is ready to receive data (i.e.
RTS
line will be ON).
0
Disabled (AT&K0)
ON or OFF
ON or OFF
Data sent by the DTE is correctly received by the module.
Data sent by the module is correctly received by the DTE if it is ready to receive
data, otherwise the data is lost.
1
Enabled (AT&K3)
ON
ON or OFF
Data sent by the DTE is buffered by the DTE and will be correctly received by
the module when it is ready to receive data (when the UART is enabled).

Disabled (AT&K0)
ON or OFF
ON or OFF
The first character sent by the DTE is lost by the module, but after ~5 ms the
UART and the module are woken up: recognition of subsequent characters is
guaranteed only after the UART / module complete wake-up (i.e. after ~5 ms).
Data sent by the module is correctly received by the DTE if it is ready to receive
data, otherwise the data is lost.
