+Self-made chiller control system
+
+UART: 115200N1, not more than 100ms between data bytes in command
+To turn ON human terminal (without timeout) send "####"
+
+Protocol: [ command line ]
+'[' clears earlier input
+'\n', '\r', ' ', '\t' are ignored
+All messages are asynchroneous!
+
+Commands:
+Ax - turn on(x=1)/off(x=0) external alarm or check its value
+Cx - set cooler PWM to x
+d  - (only when EBUG defined) go into debug commands
+F  - get flow sensor rate for 5s period
+Hx - set heater PWM to x
+L  - check water level sensor value
+Px - set pump PWM to x
+R  - reset MCU
+Tx - get NTC temperature for channel x
+t  - get MCU temperature
+V  - get Vdd value *100V
+
+Debugging commands:
+A - show raw ADC value (next letter is index, 0..5)
+F - get flow_cntr value & PB state
+T - show raw T values
+w - test watchdog
+
+
+Messages:
+MCUTEMP10=x     - mcu temperature * 10 (degrC)
+SOFTRESET=1     - software reset occured (msg @ start)
+VDD100=x        - Vdd*100 (V)
+WDGRESET=1      - watchdog reset occured (msg @ start)
