When the application starts, it attempts to listen for TCP/IP connections on ports 5000, 5001, 5004, and 5005. These ports are designated for communication with POS clients and cannot be changed.
If the application is unable to open these ports (possibly because they are already in use), it will notify the user of the issue and exit. You can check which application is using any of these ports and either stop it or reconfigure it. Alternatively, restarting your computer can often resolve the issue.
The configuration data discussed in the previous chapter is stored in a single file. EmuPSS must open this file upon exiting in order to function as a DOMS emulator. Initially, the application will attempt to access the last file used. If that file is not found or is corrupted, you will have the option to select a new file or create a new one with default settings. Furthermore, if you double-click any file with the ".emupss" extension, EmuPSS will try to open that file first.
Create new configuration file
Pressing this button will create a new configuration and save it to the selected location with the specified filename. It can be created either empty or with default devices and settings, depending on the "Create empty" option.
