Clear message

Not much to see here. If you want to know something about the machine, plug in 9600 8N1 serial and type 'help' at the prompt. Tada!

Have a look at Dispense for more user-friendly instructions.

The MIFARE reader inside the machine talks hex codes not ascii, so you will only get gibberish on serial programs like minicom. It speaks 19200 8N1 serial.
