Hello to everybody,
I've done an application that draws in a frame the trajectory of a
robot. The robot position is readed through the serial port, and
several commands are wrote through the same port to change the
direction of the robot.
The trajectory frame is managed by an applet, and the project works
good when the applet is called by a html document allocated in the
same local machine under W98 where the classes and the serial port...

hi,
I am using Win XP and writing an application to check POS devices
(printer and cash drawer).In the application I need to choose the port
which the device is connected to. If the port chosen is wrong or the
device is off power, a communication error message should be
displayed.
I am using FileOutputStream and FileInputStream to send and receive
data from the ports. When parallel port is used, I got the feedback
when the printer is...

Many moons ago, I took a class in embedded control at school. The
course focused on a micro-controller mounted on a small electric car
that was programmed using simple C code. The micro-controller chip had
several pins, some of which were for output and some were for input.
The crux of the project was to make the program set the ouput pins to
high or low to drive the servos and motors and read the input pins that
were attached to various...

the serial port accessible via a web service.
The web service and the legacy application would be running on the same
machine. The mobile application would access the web service via a network

I've done a fair amount of Googling for information on reading the serial
port in C++ (and in Linux). Unfortunately, out of every 4 hits, 1 seems to
be an unanswered question, 1 is someone saying, "That's easy, there's a lot
out there, Google it,", 1 is a discussion on it without examples and the
other is who knows what.
I did find some info on it and have been experimenting. The one example
that I liked the best in terms of...

You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
