External Interrupt (~INTR)
The WISMO Quik Q24x6 Series provides an external interrupt input (not
managed in the standard AT commands firmware). This input is very sensitive
and an interrupt is activated on high to low edge. If this signal is not used it
can be left open. If used this input has to be driven by an open collector or an
open drain.
This input is used for instance to power OFF automatically the module.

For this, the application has to send AT↵. If the application manages hardware flow control, the
AT command can be sent during the initialisation phase. Another solution is to use the +WIND
command to get an unsollicited status from the module.
