* This is a small application that demonstrates how to make the LEDs on

* Written by Ed Okerson ([e-mail])

*
* The ixj driver uses the ioctl IXJCTL_SET_LED to determine which LED to
* turn on, you pass it a char value and each of the l.s. bits represents
* an LED.  If the bit is 1 the LED will come on, if the bit is 0 the LED
* will go off.
