Hi All,
I am writing a polling controller for an RS-485 line that has
several addressable devices connected.
It is a small access control system.
All is well- the code runs for anything from three hours to three days, then
sometimes when I get a comms error and have to send out a nak character, it
fails hard...
The traceback below pops up. - the first lines are just some debug prints.

Hi,
I am trying to access Serial Port in XP. I am using Dev-C++ IDE that
uses Mingw as a compiler. I just want to know how I can open up serial
port on COM1 and write some data. I have searched quite a bit over the
web and could not find anything useful. I don't want to use Visual C++
or Cygwin, linux, etc. If any of you guys have some little tid bit of
code that would be great to look at.

For the most part this works perfectly.However, there appears to be a problem where multiple instances of the application are running in different Windows XP environments.
It seems...

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...
