SMS Tunnel Send Mode controls how an SMS tunnel behaves when a outbound messages originate locally.
SMS Tunnel Send Mode can function in a number of ways:
Disabled: data read from the Serial Line is never sent in in outbound message.
Always: any data read from the Serial Line is always sent in an outbound message.
Start Character: only data read on the Serial Line following the Start Character is sent in an outbound message.
Modem Emulation:data read on the Serial Line is sent by an ATD command.
When the Start Character is received on the Serial Line, data following it is sent in an outbound message.
The Start Character may be designated as a single printable character or as a control character.
Control characters may be input in any of the following forms:
<control>J or
0xA (hexadecimal) or
\10 (decimal).
Enabling Flush Start Character prevents forwarding of a start character from the Serial Line in a message.
Disabling Flush Start Character allows forwarding of a start character from the Serial Line in a message.

Flush Serial applies at the time when a outbound message is sent to the cellular device.
If Enabled, any buffered characters from the Serial Line will be discarded when a outbound message is sent to the cellular device.
If Disabled, any characters received on the Serial Line will be buffered and sent after when a outbound message is sent to the cellular device.
Block Serial may be enabled for debugging purposes.
If Enabled, incoming characters from the Serial Line will NOT be forwarded as a message to the cellular device. Instead, they will be buffered and will eventually flow off the Serial Line if hardware or software flow control is configured.
If Disabled (the normal setting), incoming characters from the Serial Line are sent on into as a message to the cellular device. Any buffered characters are sent first.
