Need to improve the command list and handler

• 1-9 to set the target Voltage/Current in multiples of 1000mV/100mA
• c to switch to Constant Current Mode
• v to switch to Constant Voltage Mode
• + to increase the target Voltage/Current depending on mode, in 50mV/25mA increments
• - to decrease the target Voltage/Current depending on mode, in 50mV/25mA increments
• Konami code makes the unit self distruct. Removed due to misuse.
