3. The "Max temperature since cartridge loaded" value is ASCII encoded in bytes 22 29 of the
incoming data.

4. Translate each character received from ASCI to hex numbers.
For the example above: 30 30 30 30 31 41 37 34 = 00001A74h
5. Convert this number to decimal = 6772
6. Divide this number by 256 to give the temperature in °C = 26.4°C
