I'm trying to use the RS232 class that was in the Platform SDK (i think).
Has anyone else used this with events successfully? Here's what i've got:
======================
Public WithEvents bbsPort As Rs232 = New Rs232
With bbsPort
.BaudRate = baud
.DataBit = dataBits
.Parity = parity
.Port = comPort

I want to write to the pins of an RS232 without using the serial
protocol. The use would be every pin could act to complete a circuit
in customized hardware. I could use python to communicate serially to
a BASIC stamp or a Javelin stamp and then use the stamp to set however
many pins as 0's or 1's but should it be that hard to do with python.
I've looked through how python does serial with the "serial" module but
it just uses Java's...

I found the RS232 class from MS's 101 VB samples.
Writing to the port works fine. (I've got hyperterminal on the other comm
port and a crossover cable between COM1 and COM2)
The port is opened with:
Public switchcom As New Rs232
switchcom.Open(2, 57600, 8, Rs232.DataParity.Parity_None,
Rs232.DataStopBit.StopBit_1, 512)

Hi all.
I want to control two different instrtument but have simliar
functionality.
Acually the fisrt one is controlled by using serial communication, and
the other is controlled by LAN communication.
The number of instruments will be extetned by 5 or more.
So If user select instrument (ex. by selection of combo box items), I
must do right procedure of contolling proper instrument.

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...

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,...
