Hi, Angelo!

Hmmm.... I have not tried the parallel port as an 'input' device...  But I
have made it be able to output raw bytes... like this:

FOR X = 0 TO 255
    OUT &H378, X            ' output byte to parallel port

    FOR ZZ = 1 TO 10: NEXT      ' dumb wait loop
NEXT

"&H378" is the address for the parallel port.  I have successfully played
sound files on my LPT-DAC using an algorithm like the one above...

Good luck...

Victor
