- None - no outputs.
- Screen - diagnostic outputs are displayed only on the screen (in the window of process the D2000 KOM process).
- Screen & Disk - diagnostic outputs are displayed on the screen and they are saved in LINE.LOG text file, where LINE is the logical name of a particular line. The output file line_name.log is placed in the directory TRACE, which is a subdirectory of the application directory. This directory is created automatically and the maximum size of the file is 10 MBgiven by the "Maximum trace file size" parameter. The oldest logs are deleted, new diagnostic logs are stored at the end of the file. Error logs are saved into this file automatically, although the "Monitor & Disk" radio button is not enabled. Error logs are saved automatically, together with the time and date of their occurrence.
- Disk - diagnostic outputs are saved only into a file on disk (see "Monitor & Disk"). Error messages are also displayed also on the screen.on the screen.
Note: Diagnostic outputs written to disk were originally written line by line, i.e. opening the file - writing a line - closing the file. This behavior caused the file modification time to change constantly, which was a problem on some SSDs and caused them to wear out. From 04/03/2024, they are written in such a way that the file is open for a long time and is closed only once every 60 seconds. Subsequently, the file size is checked to see if it has exceeded the size given by the "Maximum trace file size" parameter (if so, it is renamed as described above). Subsequently, the file is opened again (after renaming, a new file is created). The original behavior can be turned on with the start parameter /E+RTM.KOM.FLUSH_LOGS or while the process is running by activating the debug category (Debug info) RTM.KOM.FLUSH_LOGS in the D2000 System Console.

The name of the tab depends on the communication protocol selected for the station. It contains special parameters of the communication protocol and they are described in the documentation of the respective communication protocol.
...
Selection of line communication device. For asynchronous communication lines on the Windows platform, there are used the device names COM1, COM2, etc are used, on Linux /dev/ttyS0, /dev/ttyS1, etc.
Line modes
The table displays the parameters of individual modes of a particular communication line. These parameters are transferred into the communication process as parameters for the setting and behavior of the communication channel. Line, in dependence on category, allows defining several different sets of parameters for communication (up to 4). The choice of particular sets of parameters (mode 1, mode 2, mode 3, or mode 4) that are used for the communication depends on the value of the Line mode spin button in the configuration dialog box of a Station object, that uses the communication line. This procedure enables the communication of stations, which communicate with the use of various parameters of the communication line (Baud rate, number of bits, etc.) via one physical line. Parameters of line modes are configured in the dialog box, which is opened after double-clicking the numerical level of a particular mode in the displayed table.
