3.1.2 Testing the Serial Interface<br />
Functioning of the interface and of the connected GSM module can<br />
be tested after entering the data required for the serial interface.<br />
Place a check-mark in the "Protocol..." checkbox and then click on<br />
the "Open" button.<br />
Illustration 3-7: SMS Register Card<br />
While the interface is being opened, the red field under the "Open"<br />
button will blink. The "Open" button is then re-named to "Close".<br />
The address of the SMS Service Center and the IMEI number (refer<br />
to "About" register) are selected and displayed. If the interface has<br />
initialized properly, then the signal display field changes from<br />
blinking red to continually green.<br />
