To whom it may concern,
The serial port server 'cnhd38' has been terminated (on who's
initiative, I don't know).
It affects the users of the (at least) following nodes:
cnhd36, cnhd44, cnhd45, cnhd46, cnhd47.
The new terminal server to use is called 'msp-t01'. The port
numbers that are of interest for the nodes mentioned above are
as follows:

I am new to hardware programming.
I need to write a program for reading data from Card Reader which connects
to the PC windows 2000/XP OS through Interfacing The Serial / RS-232 Port /

Hi,
I am making a prototype system with Remoting in the bottom of the system. An
XML Web Service is using the remote object on an IIS to present data.
I am using a TcpChannel for communicating between the XML Web Service and
the host for the remote object. Within the host a port is defined and the
channel registered. It starts listening for requests. The destination port is
therefore clearly defined.

I know this is a difficult one to answer, but I am interested in opinions on
what hardware upgrades would be recommended with the following.
Access 2000 running in a split config, but all in Terminal Server. Currently
15 users. This means that all files reside on the server and all processing
happens there. Back-end is currently Access, but it will be upsized to SQL
Server . So for this question assume SQL Server back-end.
So what...

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

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....

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
