Warning: Do not connect the TEST-PIN terminals (pin 11, 24, 29 and
30) or the modem may malfunction.
Note: The voltage range of most of the modem input pins is typically
0-3.3V, however, 0-5V can be used for compatibility with conventional
logic, unless otherwise stated.
A description of the above pins follows.
