21 June 2003.  We're now using /dev/parport?, the user mode parallel
port driver, to bit bang the printer port bits.  givelp1 is no longer
needed.

Below is the old way, but it's no longer required.
---------------------------------------------------

If you're getting seg faults trying to use microtune, fm_demod2 or
other examples that twiddle the microtune eval board, you must use the
"givelp1" command to invoke them like this:

      $ ./givelp1 ./fm_demod2 102.5 103.9

The "givelp1" command gives uses the "ioperm" system call to allow the
command on the rest of the line direct access to the i/o ports for
LPT1.  We bit bang them directly to control the PLL on the tuner eval
board. 

Note that givelp1 must be setuid root for it to get it's job done.
