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 am working with a simple Java program which communicates over the
serial port with a GSM modem.
Using Hypertermial, I can send messages and need to press control-z to
process the messages. I have created a PrintStream over the serial
port, but I do not know how to send control-z from the program!
I fin in another Google- thread that control-c equals decimal 3:
But what is then the equivalent of control-z, and how should it be...

Many moons ago, I took a class in embedded control at school. The
course focused on a micro-controller mounted on a small electric car
that was programmed using simple C code. The micro-controller chip had
several pins, some of which were for output and some were for input.
The crux of the project was to make the program set the ouput pins to
high or low to drive the servos and motors and read the input pins that
were attached to various...

Hi there
I'm trying to find part serial numbers between 2 numbers. The user selects a
part number from a combo box and then enters a range of serial numbers into
2 text boxes and the resulting query should find every machine that has that
part number between the serial number range.
The problem is that the serial number stored is a text field and the results
are not what they should be.

Hi All,
I'm trying to connect to a virtual port (COM19, OUTGOING, "Bluetooth
Serial Port") using VS2005 System.IO.Ports.
When I ran the ff code below here's what happens.
1) VS2005 Compiles w/o errors
2) My Nokia 6600 prompted me the message "Accept Connection request
from DEMON?"
note: DEMON is my computers name.
3) Using my Nokia 6600, I hit the button that refers to the "Yes"

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...

Hi all,
I am fairly new to python, but not programming and embedded. I am
having an issue which I believe is related to the hardware, triggered
by the software read I am doing in pySerial. I am sending a short
message to a group of embedded boxes daisy chained via the serial port.
When I send a 'global' message, all the connected units should reply
with their Id and Ack in this format '0 Ack' To be certain that I
didn't miss a...

please help me! I come across a problem.
Now I develop a finger print management system which is based on B/S.When
users click a button in the web pages, a device connected to the COM1 serial
port of the client machine starts to work.
Now I wrote the code which is in charge of serial communication in the

server's serial port that starts to work,not the clients!!

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:

Here is the code in...

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,...
