Communication with the PC is done via COM3 with special telegrams. The
PC sends a lamp telegram to the keyboard controller and receives back a
key telegram. All keys that have been pressed since the last lamp telegram
are marked on this key telegram.
Lamp Telegram (Receiving telegram)
After receiving the lamp telegram, all coded LEDs switch on.
