I am using the RS232.vb class to talk to the serial port. The problem I am
having is when I try to read if anything is on the comm port. I call the
read method, with the number of bytes I am expecting to read. As long as I
know the length of the command that I will be getting on the input of the
port it works great.
The problem is when I don't know how long the data I am receiving is. If I
request more bytes than I know I am getting...

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

Hi!
My application uses Rs232-class, which was shipped with "101 VB.NET
Samples\Framework - Using the COM Port".
I need to sent certain kind of string into peripheral equipment attached to
COM1-port , and after receiving this string of my application this equipment
should return string back into my application.
Is it possible by using this Rs232-class to get return string after sending
string into COM-port first? I haven't succeeded...

I was reading about how to control the COM and LPT port using VB .NET.

an example program on the site of Microsoft. You can find it overhere:
http://www.microsoft.com/downloads/details.aspx?FamilyID=075318ca-e4f1-4846-912c-b4ed37a1578b&DisplayLang=en
I did found a lot about the RS232 port on the Internet, but i haven't
found the same amount of...

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...

Hello,
Just wondering if anyone can advise. I am trying to remotely control Powerpoint using a microprocessor. I am using RS232 (COM1). The idea is that the microprocessor sends ASCII strings to the PC and Powerpoint changes to the corresponding slide. For example:
01n - Go to slide 1
05n - Go to slide 5
02n - Go to slide 2, etc
I have managed to get a VBscript macro going in Powerpoint. Once the show begins I click a button to...

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...
