7.1.2 Serial Modes
 PPP Mode: The RLXIC-SG uses PPP to communicate with a device or
computer connected to the serial or USB port.
 SLIP Mode: The RLXIC-SG uses SLIP to communicate with a device or
computer connected to the serial or USB port.
 UDP and UDP PAD: Any data received on the serial port is assembled into
UDP packets, and sent to the session's associated IP address and Port
(described later). Any responses received from the associated IP address
and port destined for the Device Port are unwrapped, and sent out the serial
port.
 TCP and TCP PAD: Any data received on the serial port is packaged into
TCP messages, and sent to the associated connection's IP address and Port
(described later). Any data received from the TCP peer is unwrapped and
sent out the serial.
7.1.3 Data Communication
 Public and Private Modes: The method used by the RLXIC-SG to pass an
IP address to a connected device.
 Keepalive: How the RLXIC-SG maintains its connection to the cellular
network.
7.2 Basic Modes
7.2.1 Start up Mode
The serial port of the RLXIC-SG can be configured to enter any of the modes
automatically on power up (in most cases, this is also after it has registered on
the cellular network). This is done by setting the Startup Mode Default to the
desired mode. If this setting is non-zero, the modem will enter the specified mode
after 5 seconds. If you want to cancel this behavior, the ATMD0 command can
be used before the 5-second time-out expires.
You can configure the Startup Mode in AceManager at part of the UDP
group.
