.\"O Before 1.1.54, the LEDs just reflected the state of the corresponding
.\"O keyboard flags, and KDGETLED/KDSETLED would also change the keyboard
.\"O flags.
.\"O Since 1.1.54 the leds can be made to display arbitrary
.\"O information, but by default they display the keyboard flags.
.\"O The following two ioctl's are used to access the keyboard flags.
