+==== Hardware recovery unit ====
+station-supervisor daemon running on station computer should use external support device for error outputs.
+Connection management will be self controlled in device. Interface
+between hardware recovery unit and main station computer should be
+terminal based.  The terminal functionality should be provided by
+station-supervisor monitor software (if it is running, otherwise by
+standard system console) in system console mode station
+supervisor-should write debug output on this device (similarly to dmesg
+for example)
+Technically the link between main computer and hardware recovery unit is implemented on RS232 serial interface.
+==== Web monitoring interface ====
+Web access is primary diagnostic interface. Terminal is secondary as
+backup.
+Moreover web access is intended as file based. File based means that
+station-supervisor uploads an diagnostic file to webserver. Webserver
+takes this file (probably from more than one station) and serve a web
+page with stations status information. User interface in this case is
+limited only to modification of an station-supervisor configuration file stored
+on webserver. Configuration file may contain an parameter for station reboot
+request. After station-supervisor will notice change or update in the
+webserver stored configuration file, station-supervisor reboots the station and
+update its parameters according to actual config file.
+This approach is needed, because we usually have not direct IP
+connectivity from Internet to stations.
