AW: Steppers via the Parallel Port?

["Till Franitza" <xfa-at-isw.uni-stuttgart.de>]

Hi Adam!
Yes. This (to give pulse and direction for up to 6 steppers via parallel
port) works very well.
But to detect encoder Feedback directly via parallel port whould put a too
heavy load on the processor. I do not think it would even work with
reasonable resolution.
