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 Tunnel Packing Mode:
1. Select
Tunnel > Packing Mode
at the top of the page. The Tunnel 1 Packing Mode page
appears. Depending on the Mode selection, different configurable parameters are presented
to the user. The following figures show the display for each of the three packing modes.
