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 weirdest things happen. For example,
sometimes it gives error messages, sometimes the application just stops
(vanishes is the correct word) and some other times VS IDE halts and
completely goes away. That usually happens if I put the mouse over any
variable and try to inspect its value.
For me it smells like threading problems (and if it smell like a duck and
walk like a duck...).
What is the best practice on handling the received data once it arrives (and
triggers the event) on the serial port? Do I have to synchronize it with the
main app thread?
Cheers

If you have data that both are accessing yes you have to synchronize them.

The think is that right now, no, there's no thread concurrency. The problem
only happens in the debugger, and it happens very uglyly. So I was wondering
if I'm doing things the correct way.

Hi,
I need to write binary data to a serial port. I am using this function:
#include <unistd.h>
ssize_t write(int fd, const void *buf, size_t count);
I am able to write a alpha-numeric character to the port using this:
write (filedescriptor,"a",1);

I have a class that creates an instance of the seril Port.
Every thing works fine except whenever I receive data I cannot display the
recieved data. I get no errors but the recived data seems to just go no
where.
I can see the recived data in my serial receive function but when I either
raise an event
with it or try to display it in a text box nothing happens. I do use
beginInvoke on the text box.
If I trace the code through it all...

I have a class that uses the serial port class
Private SerialPort as New SerialPort
When I receive the asyncronous serial port response it appears that data is
on a different thread than my UI.
When I try to raise an event in my class my frmMain doesn't get the
callback. i think this is a threading issue.
Question is how do I get the serial port response from my vb class to my
main form.

Hi,
This apparently is a common problem and I've yet to read a solution that
actually works for my specific situation.
I have a Zebra RW220 printer that I connect to via Bluetooth connection
mapped to a serial port. The application I'm writing runs on a Windows Mobile
5 device, so there's no built in printer support and I have to use a serial
port.

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
