Hello

from the ikbd's doc :

The special codes 0xF6 through 0xFF are reserved for use as follows:
     0xF6            status report
     0xF7            absolute mouse position record
     0xF8-0xFB       relative mouse position records(lsbs determind by
                      mouse button states)
     0xFC            time-of-day
     0xFD            joystick report (both sticks)
     0xFE            joystick 0 event
     0xFF            joystick 1 event

So, this waits for an event on joystick 0
