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).

Hello,
Someone can tell me why I dont get serial port events in a Service, I
created a separate Thread to open the port but no events are coming up (the
same happens when I use the timer component, using the System.Timers.Timer
it works fine)
tnx in advance

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...

I set up two virtual COM ports 3 and 4 using com0com. I tried to test
it with the following program. However, the DataReceived event
handlers never get called. Can anyone with SerialPort class
experience double check my code so I can narrow it down to com0com not
being setup correctly?

using System.Collections.Generic;

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

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....

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...
