Serial to Ethernet Connector - UDP connection settings
To configure advanced connection settings, please, activate Advanced mode by enabling the corresponding button on the main toolbar. Now switch to "Connection prefs" tab (stands for Connection preferences) in the main window, you will be shown the following set of features:
When using UDP/IP connections, you are able to configure the following settings:
Connect to remote end only when local virtual port is open checkbox specifies whether connection attempts should be made only after virtual port is opened for communication by your application.
Do not buffer size data for fast response checkbox is used for disabling "Nagle algorithm", to achieve maximum speed of response if small packets are transmitted over network, note that this will cause traffic increase. If you are not sure, please, do not modify this option.
From this list
you are able configure the following:
Add pause between packets option enables you to set a pause (in msec) between transmitted packets. It is necessary when packets transmission is frequently used in UDP connection and the consequence of that can be data losses through their queue overflow. Thus by adding pauses you can prevent this from happening.
Before sending data wait for option is used for setting a pause (in msec) after which all received data is sent to remote end.
Send data when block reached the size of option is used to send all received data to remote end when block reached the size of the specified value.
Send data when received char with code option is used to send all received data to remote end when char received with specified code.
Default port settings option is located below, which allows you to either manually assign predefined serial port settings (for instance you have legacy serial port device that has specific parameters) or fetch them automatically from the remote end. Please, note this option is not available (grayed) if you are creating virtual serial port since communication parameters are fetched during handshaking process.
You can refer to Connection settings (server) section for more info about these parameters.
If Use raw data transmission algorithms checkbox is used, you are able to specify the client's access rights to the local COM port which lets you manage communication direction. You can enable or disable port read/write access rights.
