Hello to everybody,
I've done an application that draws in a frame the trajectory of a
robot. The robot position is readed through the serial port, and
several commands are wrote through the same port to change the
direction of the robot.
The trajectory frame is managed by an applet, and the project works
good when the applet is called by a html document allocated in the
same local machine under W98 where the classes and the serial port...

Hi,
I know that the System.IO.Ports.Serial port event for receiving data
(DataReceived) happens on a secondary thread, and that if there will be any
interaction of that data with the UI, it should be done through invoke.
Right now my application receives serial data and a class hierarchy is
responsible for handling it.
If I run the application, everything seems to work fine, but if I put a
breakpoint on it and try to follow, the...

Hi,
I'm writing a couple python applications that use the serial port
(RS-232) quite extensively. Is there any way I can monitor all activity
on the serial port and have it printed as the transactions occur? I'm
trying to reverse engineer a microcontroller serial routine and I'd
like to see any response the chip sends back.
Regards,
Ken

I'm a newbie that is still struggling with OOP concepts & how to make things
work they way I want. Using Visual C# Express, I have a form in which I added
a user control to display a graph, based upon data received via the serial
port. If I run the serial port in the main form code, I can get data and,
using public properties of the user control, transfer the data to be shown on
the graph. However, I am trying to add a feature that will...

Hello,
My soft passively listen to a device sending +- 300 bytes of data each
second. After several hours of work, the soft abruptly stops receiving
data without any error, (while the device sends properly, of course)
and I need to restart it (the python soft) to "reactivate" the ports.
I read that when the serial port encounters an error (frame error or
so, I imagine?) it stop receiving data until the library function...

For those who have found it impossible to get help in communicating with Wasp's WDT-2200 Barcode Scanner through a COM Port, except by using their supplied DTComm software, I am presenting what I have found through use of a Protocol Analyzer connected to the COM port, and how I have managed to upload (from Scanner to Computer) a file holding transactions recorded by others using the scanner to "Issue Parts".
Quickly though, allow me to note...

Has anybody perhaps have code to check the serialport of the PC(rs232) for data received from a a rfid scanner, and if its available, then populate it to a textbox on a form.
i currently use 3rd party logger software but it is not very stable. The hex characters received through a serial port are converted into numbers and then transmits these numbers to the app as keystrokes. i.e 0004, or 0005, etc. followed by a comma and "ENTER".
i use...

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,...
