If an application is reading data from a serial port, How can I open the
same serial port with another application?

I am having trouble with "ACCESS DENIED" error messages in a VB.NET 2003
application when attempting to open
serial comms ports.
The application has 2 ports that connect via serial cable to 2 different
hardware devices to transfer binary data to the application. The setup
screen enables the user to select COM1 -- COM8 via combo boax for each port.
Then they click "Apply" to open the ports.

I'd like to write a program in VB.Net that handles serial communications to
several devices. VB.Net 2003 does not have adequate built-in serial
communications. I heard that 2005 will have that. Has this serial
communications functionality been built into 2005 Beta yet? If so, is there
any reason I can't get the Beta and create the program with serial
communications now?

Hi All,
I've written an ASP.NET application (webservice) that does simple serial
communications via the .NET 2.0 SerialComm object.
The application runs fine on my development machine. The problem is when we
try to deploy it to another machine we receive: ACCESS IS DENIED TO COM1 PORT.
We have tried unsuccessfully to get this to work. We have tried the following:
1) Assign the IUSR.... account to Administrators

Hello,
Is there a way, in .NET, to determine what are the avialable Serial
(Communications) Ports on a Windows OS and is there a way to determine
that port isn't being use other than attempting to opening the Serial
Port and catching the associated exception? Thanks
If there isn't a way to determine the Serial Port within .NET I would
be willing, I guess, to use a WinAPI is that was the only way.

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,...

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...
