Tunnel – Packing Mode
Packing Mode takes data from the serial port, packs it together, and sends it over the network.
Packing can be configured based on threshold (size in bytes, timeout (milliseconds), or a single
character.
Size is set by modifying the threshold field. When the number of bytes reaches the threshold, a
packet is sent immediately.
The timeout field is used to force a packet to be sent after a maximum time. The packet is sent
even if the threshold value is not reached.
When Send Character is configured, a single printable character or control character read on the
Serial Line forces the packet to be sent immediately. There is an optional trailing character
parameter which can be specified. It can be a single printable character or a control character.
To configure the Packing Mode for a specific tunnel:
1. Select Tunnel on the menu bar, if you are not already in the Tunnel web page.
2. Select a tunnel number at the top of the page.
3. Select Packing Mode. The Packing Mode page for the specific tunnel appears.
