- * SYSMON test
- *
- * This test performs the system hardware monitoring.
- * The test passes when all the following voltages and temperatures
- * are within allowed ranges:
- *
- * Temperature -40 .. +90 C
- * +5V +4.50 .. +5.50 V
- * +5V standby +3.50 .. +5.50 V
- *
- * LCD backlight is not enabled if temperature values are not within
- * allowed ranges (-30 .. + 80). The brightness of backlite can be
- * controlled by setting "brightness" environment variable. Default value is 50%
- *
- * See the list of all parameters in the sysmon_table below
