Flush Mode (Buffer Flushing)

Using this parameter, you can control line handling and network buffers with connection

startup and disconnect.

FlushMode ( 0) ? _

You can also select between two different packing algorithms.

Note: All bit positions in the table that are blank represent “don’t care” bits, for that particular

option, which can be set to either a 0 or 1 value.

Table 7-11. Flush Mode Options

Function

Input Buffer (Serial to Network)

Clear with a connection initiated from the device to the network

Clear with a connection initiated from the network to the device

Clear when the network connection to or from the device is disconnected

Output Buffer (Network to Serial)

Clear with a connection initiated from the device to the network

Clear with a connection initiated from the network to the device

Clear when the network connection to or from the device is disconnected

Alternate Packing Algorithm (Pack Control)

Enable

Pack Control

The packing algorithms define how and when packets are sent to the network. The standard

algorithm is optimized for applications in which the unit is used in a local environment,

allowing for very small delays for single characters, while keeping the packet count low. The

alternate packing algorithm minimizes the packet count on the network and is especially

useful in applications in a routed Wide Area Network (WAN). Adjusting parameters in this

mode can economize the network data stream.

Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not need

specific functions.

Note: All bit positions in the table that are blank represent “don’t care” bits, for that particular

option, which can be set to either a 0 or 1 value.
