-On Window systems it is not possible to run several BNC jobs in parallel on the same host because processing options are saved in the same Windows register. However, this is possible on Unix/Linux/Mac systems where the configuration is saved in files. You may start several BNC jobs from shell scripts, each script with its own (re-)definition of $HOME directory (e.g. export $HOME=/home/user/bnc_test) before calling BNC so that the configuration file is expected e.g. at '/home/user/bnc_test/.config/BKG/BKG_NTRIP_client.conf'.

+As an alternative, directory $HOME/.config could be overridden by the user by setting the XDG_CONFIG_HOME environment variable. Command 'export XDG_CONFIG_HOME=/home/temp' would lead to a configuration file /home/temp/BKG/BNC_NTRIP_Client.conf.
