We have some equipment that communicates at 57600 baud RS232. The path from
the PC is USB to a Phillips USB hub, then off of that a TUSB3410 USB/Serial
converter. The driver for the 3410 chip creates a "normal" comm port (like
COM3). There is a C++ program that has no problem talking to the equipment,
but two Python programs have trouble. One is a big, scary, controller
program, and the other, since that is the one I'm having trouble...

I wrote a program that communicate with SerialComm. In every 300
milliseconds, my program continuously send & receive data via the serial
port once the program starts.
My program is once in a while, the serial port seems corrupted because when
my data is sent, it doesn't go through the serial port, so as same to
receive process. In order to fix this, I have to close the port and reopen
the port again.
Why?!! Is there any way to fix...

Hello there,
I've got a strange problem using the readline method in vb2005 for
reading the serial port.
If I use the readchar method I can receive one character from
serialport. This is the code I use:
Function ReceiveSerialData() As String
' Receive strings from a serial port.
Dim returnStr As String = ""

The sub below reads the value of position from my serial write
command. However i need to read only the (3) and (4) index of the byte
array and then need to convert it into a integer. When i get to the

How can i only grab position (3) and (4) and then return there values

A baffling end to my week! I open my serial port on my Debian PC (Debian version 5.0.1) I have a decent Null Modem lead going to another PC (I'll call it PC#2), with its port open with the same parameters. I send a series of bytes from the Debian PC which comes through, no problem.
I reply from PC#2, but the read buffer of the Debian PC's port shows nothing. What's more, the message gets sent directly back to the PC#2, with certain bytes...

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
