Here's my problem.
I'm using Visual C# 2005 Express for a small project that requires simple AT
modem commands to be sent to an external serial device. The device requires
2400 baud, no parity, 8 data bits, and 1 stop bit. Should be easy enough,
except that I cannot get the SerialPort component included with C# Express
to talk with this box.
I know the box itself is working correctly because a Visual Basic 6.0
application that I...

I posted this question in another forum, but realized I would probably want to port this to .net if it was possible. So, does anyone know how to control a camera using VISCA/RS-232C Commands with VB or VB.Net

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 all,
Does anyone have an example on how to implement the new SerialPort Class in
VB.NET? I have been able to create the class, send (.WriteLine) to the port
and Read from the port but cannot figure out how to use the Events to tell
my program that data is available in the serial port buffer.
I have searched the internet and MSDN and there doesn't appear to be any
full example on how to do this simple task.

Hi everybody,
i have a question concerning the serial communication over USB.
Im using the serialport to send AT commands to a Wavecom GSM modem.
When i'm sending the commands via my RS232 (COM) port to the modem, all
is working fine. But if i'm using the USB port i'm confronted with a
weird problem...
I can send the commands, but the modem is not answering at all.

I'm trying to use an external USRobotics USB modem (Model 5633B) in
Vista - and talk to it via AT commands from my C# application (using
VS2008 + .Net 2.0). Downloaded the Vista drivers, and it comes up as
COM12. I also have a built-in modem in this laptop (COM3).
I started off using CRT4 (old terminal app like Hyperterm) and can open
and use both the modems, sending AT commands to...

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;
using System.IO.Ports;

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,...
