/* Hardware Protocol */
* The signals are transmitted as TTL levels (0V and 5V) (unlike +/-12V on RS232) with 5V reference voltage (unlike 0V on RS232)
* The receiver should pass the TTL signal through an Opto-Isolator
* The 31250 Hz baudate baudrate isn't a standard RS232 rate
* MIDI is one-directional (MIDI OUT implements only TX, no RX, and MIDI IN implements only RX, no TX)
* There are no control signals like CTS/RTS/DSR/DTR used
