When Tunneling, instead of sending data on the network immediately after being read on the Serial Line, the data can be Packed (queued) and sent in larger chunks.
A Tunnel can be configured to use Packing Mode in the following ways:
Disable: data not packed.
Timeout: data sent after timeout occurs.
Send Character: data sent when the Send Character is read on the Serial Line.
If the number of bytes of queued data reaches the Threshold, the queued data will be sent on the network immediately.
If the oldest byte of queued data has been waiting for Timeout milliseconds, the queued data will be sent on the network immediately.
If used, the Send Character is a single printable character or a control character that, when read on the Serial Line, forces the queued data to be sent on the network immediately.
Control characters may be input in any of the following forms:
<control>J or
0xA (hexadecimal) or
\10 (decimal).
The Trailing Character is an optional single printable character or control character that is injected into the outgoing data stream right after the Send Character.
Control characters may be input in any of the following forms:
<control>J or
0xA (hexadecimal) or
\10 (decimal).
Disable the Trailing Character by blanking the field to set it to <None>.
