Automatic update of the Terminal OS
If an automatic update is configured, the following search is performed during the restart:
1) If a URL for the update server is stored in the terminal configuration, the specified URL is searched for a
valid Terminal OS image that differs from the current Terminal OS.
If this is the case, no further search is performed and the update procedure is started.
2) A valid Terminal OS image different from the current Terminal OS is searched for on connected USB
storage media.
If this is the case, the update procedure is started.
