Defining a New Mode for a Communications Path
To define a new mode for a communications path:
- Select Admin > Netmap to open the network map.
- Right-click the CommPath box and click Insert.
- Type the name of the communications path in the Name field.
- Click New.
- Type the name of the new mode in the Name field.
- Select TCP/IP, APPC, or UDT to identify the protocol to associate with the mode.
- To add TCP/IP settings, click the TCP/IP tab.
Refer to the following table for the name, definition, and valid values
for each field.
Field Name Description Valid Values Buffersize
The buffer size for transmitting data to and from the remote Connect:Direct® node. This value overrides the value in the initialization parameters file.
A numeric value from 256–65536.
The default is 65535.
Pacing Send Count
The number of send operations to perform before automatically waiting for a pacing response from the remote Connect:Direct node. A value of 0 indicates that there is no pacing. This value overrides the value in the initialization parameters file.
A numeric value from 0–63.
The default is 0.
Pacing Send Delay
The amount of time Connect:Direct waits before sending each outbound data buffer to the remote node. This can prevent flooding the network. A value of 0 indicates that Connect:Direct sends each data buffer as soon as possible. This value overrides the value in the initialization parameters file.
An integer from 0–86400.
The default is 0.
CRC
Specifies whether CRC checking is turned on.
The default value for the local node is OFF. The default value for the remote node is blank.
The remote node defaults to blank to simplify the use of the crc.override parameter. When crc.override is enabled in the initialization parameter, only the nodes that require a different configuration need to be changed.
OFF | ON | blank
- To add UDT settings, click the UDT tab. Refer to the following
table for the name, definition, and valid values for each field.
Field Name Description Valid Values Buffersize
The buffer size for transmitting data to and from the remote Connect:Direct node. This value overrides the value in the initialization parameters file.
A numeric value from 256–65536.
The default is 65535.
UDT33 CRC
Specifies whether UDT33 CRC checking is turned on.
The default value for the local node is OFF. The default value for the remote node is blank.
The remote node defaults to blank to simplify the use of the crc.override parameter. When crc.override is enabled in the initialization parameter, only the nodes that require a different configuration need to be changed.
OFF | ON | blank
- Click OK twice to close Mode Properties and Path Properties.
