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...

I don't know if jdbc/java code requires this, but when I use two gui admin tools I found, and I insert a row into the table using their row editor feature, both require me to enter a number for the Serial type. I thought this type was used to auto-increment an id field and that I would not need to enter anything into it? Basically we need the normal indexed ID field for each table, and we want it to auto-increment. The serial shows a function of...

I am working on device that utilizes a Motorola 68HC16 microcontroller. I am
using an old unsupported piece of crap Whitesmith's / Intermetrics / Tasking
compiler. The embedded compiler business was quite insestual for while
wasn't it? I need to write putchar so that printf can function properly.
Anyway, the compiler comes with just a shell of a putchar routine. It
literally returns the character you passed to it and nothing else. That is...

TRYING TO GET TO: I don't think polling serial port every millisecond is a good approach....

I have written an application in VB.NET 2003 that uses the SAX serial
component for RS232 communications with hardware.
The program sets up 2 serial ports so that it can talk to 2 different
hardware devices simultaneaously.
When I run the program on a desktop running Windows 2000 it works fine. When
I run it on a Laptop using XP I start having problems.
It seems that when the ports are initiated, either one will work but not the

Dear All,
I made an app in c# that uses several serial ports.
For the serial ports I use a pnp Sunix board, some with 8 serial ports
other with 4 or even 2 serial ports.
Whenever I use the development computer I don't have ay problem with
my application.

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
