2.2 REMOTE I/O CONTROL
In the Remote I/O control the Nokia 12 GSM Module is controlled with, for
example, a compatible mobile phone. Control messages are sent as text
messages from the mobile phone to the Nokia 12 GSM Module. Based on the
information in the text message, the Nokia 12 GSM Module in turn controls a
device or machine attached to it through the M2M system connector.
