I'd like to write a simple application that interfaces with the parallel port, and changes the data on it according to keyboard input. I hope I can get it to run under windows xp and / or windows 2000.
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've heard that with newer versions of windows don't let you communicate with the port directly,...

Hi All
I want to use my parallel port of my PC to control some external devices. I
am writing a program in ANSI C using the PacificC compiler. What I need to
know is how to access the parallel port ie to send data and to read the
state of the parallel port including the control lines. Can anyone
help/point me in the correct direction? I have tried the help files and the
internet but am unable to find anything relevant.
Thanks in...

I would like to know how one can use the parallel port through
c/c++.Also, how does one determine what port is
installed(EPP/ECP/SSP/PS2)?
What is the differnece between these?
What are the current sinking/drawing capacities of these ports?
If possible, please give examples in C/C++.
Thanks
I would be grateful if any ebooks/tutorials could be provided at

or anything.

Basically, I'm thinking about building a robot which can be controlled by
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 don't particularly want to :-) , instead I'd like to use Python. I'm
wondering, is there any way I...

I'm trying to make a Java program access a parallel port. Java's comm
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
people know a good solution? I'm trying to use JNI and create my own
library, but building the library gives me these errors:
ld: warning: cannot find entry symbol _start; defaulting to

hello people.
i've been trying to send an 8 byte string to my parallel port under
freebsd. the purpose is it to control a relay board.
the board simply responds to the output byte coming from the port. eg.
00000001 will set pin 1 high and flick the relay open.
todate i've attempted this with merely open() on /dev/ppi0 and numpy for
the byte array, but i just can't seem to get it working.
i know the parallel port works and i know the...

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 tried doing this? What are my options for controlling
parallel connections on a laptop with no parallel...

Hi,
Using the UserPort program that changes permissions in XP so that I am
able to write directly to the parallel port using assembler..
I'm trying to send out square wave pulses for x number of seconds. I'm
able to write and read from the parallel port, but after a few reads
and writes it crashes... how many reads and writes before it crashes
is not always the same.. sometimes it crashes at the first write or

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
