Hi there,
I'm developing an application to catch OBD sensors' data from my car.
I connect it via a RS232 interface.
Now.
with HyperTerminal I can connect and send/receive data, but I'd like to do
this from inside my C# program.
Anyone can write down a very small (or tell how to do it myself) application
containing methods like WriteToSerialPort(string what) and
ReadFromSerialPort(what).

I'm trying to convert from a lot of invoked code to c# 2.0 SerialPort code.
I can't find a way to set fOutxCtsFlow to true (maybe CTSEnable?) and
fRtsControl = RTS_CONTROL_HANDSHAKE (RtsEnable?). Also, do I need to set
the handshaking? Below is the old and attempted new (that continually gets
a timeout error on read. I upped the read timeout, but it's way too long
NOT for it to be a handshaking or other issue than the readtimeout...

Hello,

same happens when I use the timer component, using the System.Timers.Timer
it works fine)

When I try to use a System.IO.Ports.SerialPort object to read from a serial port, half of the time I have no problems. However, after I successfully read from the serial port, then close the connection, either when re-opening it (in the same instance or a new instance of my program) I get either an IOException "The Handle is Invalid" exception or an ArgumentException "The portName is invalid.
Now, I get the port name by doing this:

Hi Everyone,
I'm using the System.IO.Ports.SerialPort component to attempt to kill
an existing component opened by another application.
I use the following code:

I'm trying to send some printer commands (ZPLII) to an attached USB printer
using the SerialPort component. I didn't get very far at all. In fact I
haven't gotten anywhere.
The first problem I encountered is that a call to SerialPort.GetPortNames()
returns an empty string. In other words, NO port names are returned. I'm
not terribly knowledgable about ports but from the Hardware Manager I did
notice that I don't have the Ports and...

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...

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...
