Here's the situation:
I work at a scientific institution and I have a portable electronic
device which is used to take measurements. The device produces a very
small amount of numerical data, about 10 to 15 numbers per
measurement. This operation is performed frequently and I would like
to implement an automatic solution that moves this data across a
windows network and into the fields of an Access database application.
The device...

hello,
Does anybody know if Microsoft Dot Net supports the RS232
type of connection.
As far as I know Visual basic 6 supports RS232 connection
format.
Thanks,

Hi,
Do you know some good RS232C class? There is one in
VB.NET 101 Examples, but I think it is poor.
1.
I can't for e.g. read into my application all data
received. I must tell how many bytes I would like to
read. If I specify too many exception occures, if too
less there are still some data in buffer.

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

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,
how can I access the RS-232 hardware interface using C# and .NET2.0 to send
and receive messages to a hardware component?

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

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...
