RTC Sleep
In this mode, the modem is off except for its Real-Time-Clock. When put into this mode, the
modem can wake itself up at a designated time/interval. See Section 4.10 of the Enabler III AT
command manual for details
Serial Interfaces & Handshake (Pins 11, 13, 15, 17, 19, 21, 23, 25)
The pin naming for TX/RX/RTS/CTS/DTR/DSR is referenced as a DTE .The DTE device
should match their input pins to the Novatel Wireless M2M outputs and vice-versa.
Additionally, there are AT commands that may need to be executed in order to insure proper
operation. See the chart below.
