[hpsdr] Parallel port replacement - help needed

[Bob McGwier N4HY]

Actually Frank Brickle has done that port and is waiting on me to stop 
getting pulled in twenty two directions to finish off the SDR-1000 
hardware code.  One second after testing positively,   we will know Phil 
H's request can be met.
