How can I do this? What do I need to know? It doesn't look like the standard library (the one under my pillow) has that feature. In addition,...

I would like to know how one can use the parallel port through
c/c++.Also, how does one determine what port is

programs which I write, I'm going to interface to the robot through the
parallel port (like in this tutorial here:
linuxfocus.org/English/May2001/article205.shtml). However, I know that this
will probably need to be done in low level C. Now, although I can code in
C, I...

API does not provide me with the control I need. I need to be able to
write to the data and control pins and read the status pins. Any Java

Hi,
I want to control some motors using the parallel port.. however, my
laptop does not have any parallel ports (very few do). What I do have
is a USB->Parallel converter... I thought about using PyParallel, but
the USB->Parallel converter doesn't actually map to the LPT port ..
and PyParallel only looks for LPT ports?
Has anyone...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
